How to cut a mineral wool insulation

Mineral wool is popular and effective thermal insulation used for internal and external work when arranging residential and household buildings. A feature of the material is its unique spatial structure that provides high operational qualities. Violation of the location of the fibers leads to an increase in thermal conductivity of the product, which requires the choice of a special technology for cutting plates.

Characteristics and properties of mineral wool

Cut the insulation with tools that are best suited to its type and technical characteristics.

For thermal insulation work, such varieties of mineral wool are used:

• Stone. Consists of integrated fibers of mountain dolomite rocks. Basalt, characterized by high strength, is mainly used for manufacturing. The material is used as a heater for the manufacture of acoustic panels. Cutting stone cotton wool is easy, as it is soft and suppleted.
• Slag. It is made from waste of the steel industry. It is used more in the decoration of outbuildings, as it contains impurities of toxic materials, has a sharp unpleasant odor. It is difficult to cut mineral wool in the slabs, as it is fragile and unstable to the pressure.
• Glass. Raw materials for production are fiberglass, lime and stone baby. Consists of many intertwined glass fibers that easily break. On sale is delivered in tightly twisted rolls. It is easy to cut glass wool, as the material lends itself to any sharp tool.

The convenience of its styling and the quality of the final result depends on the quality of cutting the insulation.

Proper transportation of the material

Since the material is characterized by porosity, fragility and hygroscopicity, you need to handle it accordingly.

When transporting and storing mineral wool, it is recommended to follow the following rules:

• During loading and unloading, do not throw packaging, but gently lay, avoiding their falls and strong compression.
• Transport bales in covered trucks, laying them horizontally on a flat bottom. Fix the insulation so that it does not beat on the walls of the body.
• Store products in dry closed rooms. If this is not possible and it is stored on the street, cover with a film or tarpaulin to protect against precipitation.
• Take the slabs from the pack right before their laying. This will prevent moisture absorption and reduce the risk of random damage to the material.

The technology of insulation involves the installation of dispersal slabs, with compression for 1-2 cm on each side. Based on this, it is necessary to cut mineral wool with an error in size of not more than 0.5 cm.

Cutting tools

In the production process, to cut the material into fragments of the desired configuration, special stationary equipment is used.

At home, you can use the following tools:

• Stationery knife. Simple and inexpensive device with interchangeable blades that are easy to change as it is abrasion. Thin steel is well included in the basalt and glass material, but almost powerless in front of slag slabs. The downside is that such a product can only be cut by mineral wool up to 50 mm thick.
• Kryazuvka for metal. A great solution if you need to cut slag or stone wool with a thickness of up to 100 mm. On sale there are unilateral and bilateral canvases with small and large teeth. You can easily choose the most convenient option.
• Special knives. Products have narrow blades up to 34 cm long with teeth without wiring. The handles are specially adapted for sawing at the optimal angle. In various models, the canvases are made of cold stainless or carbon steel.
• Bukhankaya knife. The device is a good analogue of a special tool. For work, you need to choose knives with a gear, not a wavy edge. The length of the blade should be more than 15 cm.
• Cutting machine. The equipment is quite expensive, but productive. Allows you to make accurate and even cuts. Buying a machine makes sense if there is a large amount of insulation work.

The choice of a device for cutting mineral wool is determined by its own priorities, building skills and financial capabilities.

How to cut mineral wool

The main technical condition for the process is the preservation of the structure of the material. the fibers should remain intact and maintain their position in the space. In order for the division lines to be accurate and even, you should first mark with a marker using a tailor’s meter or rule. Cut the plates you need to put them on the table so that the fishing line for the cutting is on weight. After that, it should, avoiding excessive pressure, make progressive movements with the tool.

You need to finish the sawing, holding the cut fragment by weight so that it does not break under his own weight.

Safe working conditions

The main component of mineral wool are thin and sharp fibers. In the process, they come off the base and rise into the air. The ingress of these particles on the body causes a burning skin, a carving in the eyes and irritation of the respiratory mucosa.

In order to prevent harm to your own health, it is necessary to create the following conditions for work:

• exclusion of accidental penetration to the place of work of outsiders;
• removal of people and animals to a safe place if cutting is carried out on the street;
• the use of overalls, masks, respirator, hermetic glasses and rubberized gloves;
• high.quality ventilation in the room, the exclusion of flying substances in the neighboring rooms;
• cutting across the fibers in order to reduce the number of volatile compounds;
• wet cleaning with pre.cleaning surfaces with a vacuum cleaner;
• Closing the insulation by plaster, vapor.permeable or windproof film with the aim of complete isolation.

Mineral wool. multifunctional material with unique properties

Mineral wool is a fibrous material that is obtained from rocks of rocks, as well as metallurgical slags and their mixtures. Most often, global manufacturers of mineral wards use rocks as raw materials. Thanks to this, the mineral wool is of high quality, it can be operated for a long time. Когда необходима долговечная и надежная работа зданий и строений, применяют именно ее.

Mineral wool, which is obtained from domain slag, is not enough durable in conditions of temperature changes, the action of loads and deformations, increased humidity. Therefore, it is successfully used in summer cottage construction, as well as in the construction of temporary structures.

Mineral wool has unique properties:

Fire resistance. Minvata is achieved through the use of non.combustible silicate melts of rocks in the production of non.combustible. Even at high temperatures, there is no deformation of mineral wool plates, all properties are preserved. The material resists the spread of combustion in a fire, which is why mineral wool is used for insulation of rooms where various fire hazardous substances are stored. It is used even in conditions of prolonged contact with high temperature, however, without further mechanical exposure. This property is obtained due to the difference in the melting temperature of the stone fibers and used in the binder.

Biological and chemical resistance to various aggressive substances, immunity to fungi and the effects of rodents. In this case, mineral wool is fully consistent with the current sanitary and hygienic standards and quality standards.

Insignificant degree of thermal, as well as natural shrinkage. The dimensions and form of materials from mineral wool do not change for the entire time of operation. This helps to exclude the passage of the cold in the butt places. This happens when the material is seated over time.

Negigroscopicity. The ability of the material to prevent moisture penetration is quite high. So the level of water absorption is about 0.5%, which is much lower than that of other materials. To reduce the risk of moisture penetration into the material to a minimum, it is produced and stored in dry rooms or impregnated with water.repellent substances.

Vapor permeability. This property is indispensable when creating a microclimate in the room and regulating humidity level. Due to the vapor permeability of the material, unhindered removal of water vapor and condensate is possible. Stability of volume and shape in any conditions.

Low thermal conductivity. This material is characterized by high thermal resistance. So to ensure the same value as in 10 cm of mineral wool with a density of 100 kg/m.cube. It will take 25 cm of dry wood, 200 cm of silicate brick, 117 cm of hollow ceramic. This property helps to save money in repair.

The thermal conductivity of mineral wool depends on the geometry of the fibers of the material. The direction of the fibers also affects the strength. An ideal choice is material with randomly directed fibers.

High sound insulation. Mineral wool is a strong barrier for sound waves.

High strength and corrosion stability. High.quality mineral wool is a chemically inactive environment and does not cause corrosion of metals in contact with it. The more vertical fibers in the material, the higher its strength. In the presence of a large number of fibers of this type, you can use a less dense coating.

Environmental friendliness. The material is absolutely safe and harmless to a person.

Easy installation. It is easy to cut any mineral wool to give the desired shape: soft. with a knife, and a denser. a hacksaw. It can be easily placed on any surface with different configuration, since it easily acquires any form.

Durability. The service life of mineral wool, provided that the proper operation is at least 70 years. Such durability is achieved through the use of rocks of basalt stone.

Mineral wool cutting than and how to cut mineral wool in a roll and plates

A distinctive feature of mineral insulation is a structure consisting of fibers, which should be solid to ensure thermal insulation. In this regard, special attention should be paid to the cutting process. You can not use scissors for cardboard or fabric for cutting material, or ordinary dining rooms. These tools are not intended for such material, since they can spoil its appearance and worsen the beneficial properties. It is very useful for novice repairmen and builders to find out what tools are suitable for this case.

Characteristics and properties of the material

Before starting construction or repair work, the owner of the premises is conceived about what criteria you need to choose materials. Currently, the range of sales is replete with a variety of canvases that differ from each other in raw materials, price, scope of application, and operational characteristics.

The term “minvata” implies three types of materials, namely:

Glass wool (from fiberglass) is characterized by low density and high hygroscopicity. The material does not have the properties of moisture resistance, and heat resistance should not be expected from it: when a high heating temperature is reached (about 300 degrees), the fibers of the cotton wool are melted, and the material is no longer performed by the isolation function. Wolon is sold in rolls.

Glass wool is produced by a fiery way: an industrial centrifuge creates air flows that go directly to the raw materials. Due to the air flow, fibers from threads appear, and they can have different lengths, orientation and thickness.

Mineral wool has small thermal conductivity, passes steam due to cells in the structure and almost does not absorb water. In addition to the basis, there are few connecting elements, which allows it to withstand high temperature rates. The material is widely used as sound insulation and insulation for various foundations and surfaces. Produced by canvases that vary in terms of strength.

Slag wool for insulation of rooms

Slag wool is the cheapest option for insulation. The material consists of fibers that are waste operations of domain furnaces, it is not dense and does not differ in good indicators of heat resistance. If you overheat the slag cotton, it rises. Therefore, the material is not suitable for insulation of premises adjacent to thermal sources, and is also not recommended for the construction of houses.

The structure of the horizontal layer of any type of mineral wool is created in the direction of the fiber. The formation of vertical sites occurs due to elements that are randomly located. Each type of material has its own characteristics and external differences.

Are there any nuances in transportation and storage?

Manufacturers recommend storing mineral wool in a holistic package, and it is better if the pack is on a flat surface. Each pile of packages should not be higher than 2 meters. The optimal storage conditions are closed rooms resistant to moisture. It is not recommended to store insulation on the street, but if this happened, then you need to cover it with a tarp or film.

Store cotton wool only in a horizontal position

When transporting, it is worth observing the same rules: transport cotton horizontally and in a dry body of a truck. It is also necessary to provide material protection against mechanical influences and atmospheric precipitation. When loading and unloading the material, it cannot be strongly compressed.

Unpacking mineral insulation also requires certain nuances. The material should be removed from the package only before starting work, which will minimize various risks associated with damage to the insulation. By laying out the material for cutting, use its packaging as a litter. Thus, the product will not get dirty. Also, packaging can also be used to collect other garbage at a construction site.

The better to cut mineral wool?

Professionals use a special machine to separate paintings and rolls. But many are wondering: “The better to cut to mineral wool in the boards of the house to save money?””

Important! For cutting, minvates use a hacksaw for metal or wood.

In everyday life, to cut the canvas, a mounting knife is involved. This tool has one drawback, due to a small blade, it is difficult for them to cut thick plates. Therefore, I recommend applying a chancellery knife only for thin sheets. If this condition is not observed, then the canvases may become unusable.

Cutting mineral wool with a knife

Tools best suitable for cutting mineral insulation:

• A knife whose blade is made of carbon steel. It is very easy to cut such a product, in addition, its blade is well and quickly sharpened. This knife needs careful care to avoid rust. The main rule of care is to wipe the blade after washing.
• A knife whose blade is made of stainless steel. On each side there are teeth of different lengths, so it is very easy to do cutting of mineral insulation of different sizes and thicknesses. The blade quickly plunges into the stove and cuts it qualitatively. A sharp tip can make not indirect cuts.
• Special machines. Such tools are able to draw canvases along a flat line and bending. Such a function is very appreciated in industry. If you need to cut cotton wool once, then it makes no sense to purchase expensive equipment. a tool that is in the house is suitable.

Cutting mineral wool with a special saw

note! Scissors for cutting wool cannot be used.

To cut a cotton wool, it is advisable to use a special hacksaw for insulation or metal. It is used to cut material, the thickness of which does not exceed 5 cm.

The blades of the tool that you use to cut cotton wool should always be well sharpened. In this case, fibers from cotton wool will be stretched minimally. Manufacturers advise cutting cotton wool before turning the roll.

Recommendations on how to work with insulation

Before starting work, they study the instruction manual. It is required to cut and lay the layers correctly to improve thermal insulation, maintain safety for the user.

When working with insulation components, the following recommendations are used:

• Prior to use, the product is stored in a dry place without direct sunlight;
• packaging is removed only before the work;
• Professional tools are used for cutting, in their absence, you can use sharp, not blunt objects, for example, knives;
• If the product has a fibrous structure, it is additionally put on protective gloves so as not to cause allergic reactions, irritation and other dermatological problems;
• They pre.measurements do not make a mistake with the cut, otherwise it will be impossible to return the pristine type of product;
• If a part of the material remains after the work, it is placed back in the package, especially if mineral wool is used, since its fibers may fall out.

The listed rules will help make work better and easier.

Neat execution

It is important to create safe conditions

If you adhere to safety rules, you can save the health of the employee and the people around.

• It is forbidden to have cutting tools in free form, especially with direct access for children;
• If the mineral wool is used, a protective suit, gloves, glasses, a respiratory mask are pre.prepared;
• To use other products, only gloves may be required, inside which rubber spraying is applied, and fingertips are covered with silicone;
• Cutting tools should be sharpened if dumb devices are used, the cut will be uneven, when pressed, the user can damage the limbs;
• It is recommended to cut the surface in the open air, the balcony and in other non.residential premises;
• Small surpluses are immediately thrown away so that their fibers do not spread through the air, floor;
• the cut is made carefully so as not to accidentally cut the fingers or other parts of the body.

If you do not observe safety precautions, you can not only cut, but also harm the body. For example, the penetration of mineral wool into the respiratory tract can cause athletes, bronchial asthma, halflenosis and other deviations.

Safe slicing

Cutting tools

To understand how to cut the insulation of mineral wool, foam, other products, preliminarily reveals their structure and thickness. It is best to adhere to the advice of manufacturers, as they take into account these components.

In the presence of thin materials with a thickness of not more than 5 cm, you can use recommendations than cut the basalt insulation:

• a kitchen knife that has cloves at the edges (usually it is intended for loaf);
• construction knife for installation work;
• A knife for the office.

The listed items are suitable in cases where the user is trying to find out how to cut mineral wool in a stove 50 mm. They successfully cut the structure, do not cause laying, completely penetrate the thickness of 5-10 cm.

Preliminary measurements play an important role

If the thickness of the product exceeds 50 mm, more serious cutting tools are required.

• Knives for cutting insulation with a thickness of more than 30 mm. Most often they can be found in construction stores, sellers recommend that they be purchased together with the purchased material for insulation. This is a good option, since the manufacturers have already made a check for the quality and the ability to cut such a thickness.
• Saw. Before buying, they carefully inspect it, as only a tool with undamosed teeth is suitable.
• Cutting machines. They are required for professional masters. The machines are designed to cut complex shapes, for example, circles, ovals, various figures.

It is easier to cut sheets of foam or extruded polystyrene foam. For this enough kitchen or stationery knife. The situation is more difficult for users who have purchased rolled heaters (mineral wool).

How to cut a mineral plate: a review of knives and drank

To figure out how to cut to mineral wool, find out its thickness. The tool used depends on it.

• Stationery knife. Suitable only for products with a thickness of not more than 5 cm. It is better to break off the upper part of the blade to use the sharp area. The blades should be enough for it to penetrate through the entire structure, it goes out another 2-3 cm.
• Kitchen knife. Suitable products with zazubins, which are usually used for bukhankaa. Even if the tool has dulled a little, the little calls will successfully cut the material.
• Construction knife. This is a universal tool that is suitable for different products, including rolls or mats of mineral wool with a thickness of more than 10 cm.
• Kryazuvka for metal, hand saw. It has similar qualities, like a kitchen knife, as it also has a zabina.
• Stab for heater cutting. The set contains different blades that are suitable for thickness up to 30 cm.
• Professional tools. This includes machines, batteries with a cost of 3,000 more often they are used only by professional builders, masters.

Having found out the advantages and disadvantages, you can successfully select the required tools that will be needed in the future.

average cost

The basalt plate in the regions costs from 450 for a package of 0.288 m3 (sometimes you can buy with a discount of 20%), a product in rolls: 150 1 kg. 1 m3. Packaging 0.3 m3, with foil coating from 295 1 m2.

What will we cut

You can do this with different devices, depending on the thickness of the mineral wool.

• a kitchen.bukhank knife with a gear edge;
• mounting construction knife;
• stationery knife.

• Special knives about 300 mm long. Often they are offered by manufacturers of warming materials. Such a tool has teeth of different sizes for cutting mineral wool of different thickness and density;
• saws with undamosed teeth;
• Kryzuvka for metal;
• Cutting machines. Used when cutting elements of complex shape. However, for independent construction of your own home, that is, for single use, it is impractical to purchase such expensive equipment. you will have to adapt to the possibilities of other tools.

Stone wool or glass wool?

Water should be laid in gloves and in a shirt with a long sleeve.

Despite the rather similar technical characteristics, the basalt insulation has a number of significant differences from glass wool. These differences will help us understand what is better. glass wool or stone cotton wool.

First, take the plate of the basalt insulation around the corner and try to shake.

Now we will do the same with glassy. The result differs radically.

The corner could not stand the glass wool and came off.

Now we put a leaf of basalt wool double.

Put the basalt plate in half. it is good.

We produce the same manipulations with glass wool. The result is strikingly different from the previous experience.

Remember how we walked our feet on stone wool slabs? Let’s go on glass wool stoves. The result is different again.

Traces of the legs are clearly visible on the glass wool.

In addition to this visual demonstration, you can recall the well.known feature of fiberglass insulation:

• This material causes severe itching in contact with the skin;
• When getting into the eye, the help of a doctor is necessary;
• If you breathe dusty glass, you can get sick with bronchitis or asthma, and in some cases, lung cancer.

If we take a slag or minvat based on a basalt with impurities of dolomite and limestone, we will see that the basalt insulation exceeds all these types in almost all indicators.

Fireplite mat from basalt fiber.

The difference in insulation based on fibers can be very significant. One turns out to be a safe and durable tool that demonstrates unexpected properties, the other. source of disease and simply poor.quality material.

How to cut

Cutting mineral wool, it is important to maintain the shape and density of the material, not get injuries and do not cost too costly purchases. Therefore, it is important to follow the following tips:

• With independent construction, when workers do not have sufficient experience, it is advisable to consult with specialists before the start of cutting, especially if the presence of pieces of complex shape is assumed. This will help prevent unjustified insulation consumption;
• The cutting tool should be well sharpened so that the mineral wool is not torn on the fibers and less “dust”;
• When cutting the insulation, it should be borne in mind that in order to ensure a tight overlap of the mineral insulated space, it is necessary to leave the allowances of about 2 cm;
• It is better to cut roll mineral wool until it is expanded;
• Mineral boards must be removed from the package and cut one at one;
• It is not recommended to cut the mineral wool “for the future”. immediately for the entire amount of work. This increases the risk of random damage to its shape when additional transfer from place to place or folding pieces on top of each other.

Cutting minvata video

On the video. cutting mineral wool with a special tool.

Today, a method of obtaining a special type of insulation. stone cotton wool made from basalt has been developed today. Twenty years ago, such mineral wool was used exclusively for the needs of the defense industry, and today this insulation is widely used for thermal insulation of any buildings.

Mineral wool does not contain components such harmful to the environment as acrylic and phenol-formaldehyde resins. It consists only of natural binding substances, therefore it is safe for humans. This thermal insulation material not only perfectly retains heat, but also allows you to create reliable soundproofing of the premises. Minvata from Basalt is becoming more popular and already tested by time, but people still have a lot of questions regarding the technological points on which we will try to focus on this article.

How to fix mineral wool correctly?

In this case, it all depends on the type of insulation and on the type of structure on which thermal insulation is mounted. Light brands of the mineral wool are installed in the frame structures of the display. Hard mineral wool slabs are fixed with special dowels or fixed using special adhesive compounds.

When fastening, mineral wool is fixed very tightly in a wooden frame pre.collected from the racks and bars. The thickness of the frame should correspond to the thickness of the insulation. Between the rails, the interval is maintained less than the width of the mineral wool by 1.5-2 cm, which does not allow the material to slide during operation. Mats are mounted starting from the bottom of the structure, and the rolls on top. At the same time, whole pieces are laid first, and free space, for example, near doors or windows, is filled later.

Mineral wool of high density is often mounted without intermediate/supporting bars. It is fullyed for the frame and pressed without a gap to the supporting structure, after which it is fixed with dowels with a wide hat, that is, the so.called “raids” dowels for safety. In such a system, the elements of the frame are located on top of the insulation layer and crush cotton wool to the wall, in addition, brackets that pass through mats help to keep the insulation in place.

When using the method of fastened thermal insulation (wet method), the frames are not used at all, so adhesive compounds must be used as fastening. In this case, you will have to purchase a dry mixture, but necessarily designed for gluing mineral wool insulation. Recently, polyurethane glue in cylinders has become increasingly popular, which allows you to mount dense mineral wool for any reason, including wooden, metallic, polymer. This technology also involves the use of plate dowels. We considered the features of gluing the insulation in more detail in articles on adhesive compositions and wetting of the facade.

The better to cut mineral wool?

It is recommended to cut heat.insulating materials from stone wool with a hacksaw for metal or specifically for this with an intended sharp long knife, the blade of which. In any case, the equipment should be well sharpened so that the fibers burst as little as possible. Many companies producing insulation also offer their customers a cutting tool: knives about 300 mm long, as well as saws with teeth without a divorce, about 60 cm long. For lack of special devices for such purposes, kitchen loaves with small teeth and a wavy edge show themselves well for such purposes. Thin soft slabs and mats (50 mm) can be cut with an ordinary mounting knife.

Minvata, produced in rolls, is best cut before unfolding. And mineral wool plates are taken out of packs and cut one at a time. It should be remembered that during the installation of thermal insulation, the insulation should fill all the isolated space very tightly, so the allowances should be left before cutting: for plates. 0.5 cm; and for mats-about 1-2 cm.

Is it true that Minvat needs to be protected from moisture and wind?

During the operation of insulated buildings, their walls, roof and other structures should be protected from increased atmospheric humidity and from blowing with strong winds. Therefore, mineral wool insulation after installation on the outside is covered with canvases from vapor permeable moisture and windproof membrane. This allows you to prevent the penetration of cold wind and drops of oblique rain into the thickness of the wall. At the same time, water vapors from the interior, through diffusion passing through the walls, will be able to go out without obstacles.

The undoubted advantage of mineral wool is its vapor permeability, and this property should be used to the maximum. When installing mineral.water thermal insulation materials, it is not necessary to lay vapor barrier between the load.bearing wall and the insulation, since such sealing will negatively affect the climate inside the building. The lack of artificial ventilation in this case will lead to an increase in humidity and the formation of condensate, which, in turn, will cause mold and fungi formation.

The vapor barrier film is necessarily used when installing thermal insulation indoors. in this case it is installed on the warm side of mineral wool. This allows you to protect the insulation from water vapor from the premises. As a vapor barrier, reinforced polyethylene can be used, which is located between the insulation and facing.

If the design allows, between the insulation and outdoor trim, it is necessary to provide a ventilated air gap. This will help maintain mineral wool in a dry state, while without reducing the vapor permeability of the building.

What to do if you need to use cotton wool with a layer of 15 or 20 cm, and the insulation supplies 5 or 10 cm thick?

There is nothing complicated here. It is necessary to calculate the necessary thickness by formulas or using an online calculator (we talked about this in a last article), and then you can easily dial a insulation barrier from several layers. In addition, this method allows you to easily eliminate the problem of the formation of cold bridges and blowing joints. To do this, when installing the insulation, sheets of the outer and inner layers should be shifted relative to each other by 20-30 mm to reliably block the seams.

Is it necessary to use protective equipment? What kind?

Minvata is considered safe heat.insulating material, both during operation and installation. However, with prolonged work with this insulation, it is better to protect yourself, using individual protection items.

How to transport insulation correctly?

Mineral wool is one of the best, simple and common materials for insulation and sound insulation of walls and ceiling today, and is also known in some other areas of application. In addition, it is easy to mount, that is, you can independently insulate the premises.

Many people do not know how to cut mineral wool correctly without violating its structure, in this material we will consider all methods of proper cutting of mineral wool, as well as advise tools that are best suited for this.

It is customary to classify mineral wool according to the principle of material from which it is made. This follows that the mineral wool made of different source materials differs in structure. fibers, and, accordingly, and according to the type of cutting. So there are the following types of mineral watches:

• Glass minvata. Consists of glass melts.
• Stone Minvata. It is most often made from various melts of rocks.
• Slag Minvata. Source material. domain slag.

In fact, you should pay attention to the fact that sometimes mineral wool is harmful. This is due to the fact that it has dust and phenol.formaldehyde resins in it. Therefore, it is necessary to refer to this material selectively, although mineral wool cannot be attributed to carcinogens for humans.

Mineral wool cutting can be carried out both independently at home and using various equipment. Equipment for cutting mineral wool plates can be different. The question is in scale. Mineral wool cutting machine is suitable for serious and large scale. for enterprises, manufacturers, etc.D. But a knife for cutting mineral wool will become an indispensable assistant in cutting insulating materials at home.

It is important that the cutting of mineral wool does not damage the fibers, so the equipment should be selected carefully. The cut should be even. At home, cutting mineral wool rolls (the so-called “50-ka”) will be convenient using a cutting knife, but for large (“100-ki”) a special hacksaw for heater will be convenient.

If you do not know how to cut mineral wool at home, we can advise you with excellent tools best suitable for cutting mineral wool.

So, for cutting mineral wool, a good, sharp chancellery knife or a hacksaw for metal is best suited, carefully cut the mineral wool in the right directions, for greater accuracy you can draw a pencil or cut right along the ruler. The process of cutting mineral wool is somewhat similar to the cutting of paralon, only you need to make a little more effort, pressing a little more on the tool for cutting mineral wool.

The better to cut mineral wool?

Professionals use a special machine to separate paintings and rolls. But many are wondering: “The better to cut to mineral wool in the boards of the house to save money?””

Important! For cutting, minvates use a hacksaw for metal or wood.

In everyday life, to cut the canvas, a mounting knife is involved. This tool has one drawback, due to a small blade, it is difficult for them to cut thick plates. Therefore, I recommend applying a chancellery knife only for thin sheets. If this condition is not observed, then the canvases may become unusable.

Cutting mineral wool with a knife

Tools best suitable for cutting mineral insulation:

• A knife whose blade is made of carbon steel. It is very easy to cut such a product, in addition, its blade is well and quickly sharpened. This knife needs careful care to avoid rust. The main rule of care is to wipe the blade after washing.
• A knife whose blade is made of stainless steel. On each side there are teeth of different lengths, so it is very easy to do cutting of mineral insulation of different sizes and thicknesses. The blade quickly plunges into the stove and cuts it qualitatively. A sharp tip can make not indirect cuts.
• Special machines. Such tools are able to draw canvases along a flat line and bending. Such a function is very appreciated in industry. If you need to cut cotton wool once, then it makes no sense to purchase expensive equipment. a tool that is in the house is suitable.

Cutting mineral wool with a special saw

note! Scissors for cutting wool cannot be used.

To cut a cotton wool, it is advisable to use a special hacksaw for insulation or metal. It is used to cut material, the thickness of which does not exceed 5 cm.

The blades of the tool that you use to cut cotton wool should always be well sharpened. In this case, fibers from cotton wool will be stretched minimally. Manufacturers advise cutting cotton wool before turning the roll.

Today, manufacturers offer a sufficient number of heater. Each of these materials is used in certain conditions and has its own price. However, insulation is most popular that provide optimal heat conservation and have a long service life. The second no less important point is the cost that should be acceptable.

Roofing Pie system insulation scheme.

• Thermal insulation and hydrophobilization. The first parameter is from 0.042 to 0.048 W/mk. Other well.known insulation materials (for example, polystyrene foam, polyurethane foam) have approximately the same characteristics). Minvat is not able to accumulate moisture (hygroscopicity. less than 1%), which makes its weight unchanged. A distinctive feature can be called vapor permeability, which guarantees insulation and at the same time intensive moisture exchange between the external environment and the walls of the building;
• Density, strength. The insulation has a sufficient density (from 30 to 100 kg/cube. m), which guarantees high thermal insulation properties with optimal strength. The rigidity of the material is provided by the direction of the fibers; They are located in a horizontal and vertical direction;
• soundproofing. Good characteristics of noise protection are achieved due to the porous structure of cotton wool;
• resistance to aggressive environment. Cotton wool “indifferent” to alkali, acids; does not rot, is not affected by the fungus. Rodents also bypass this insulation;
• fire resistance. Basalt wool can withstand heating up to 700 ° C. This protects the structure from complete destruction during fire and gives time to evacuate the residents;
• Health safety. In production, resins containing harmful substances (formaldehyde, phenol) are used). However, compliance with the technology involves their introduction to the insulation in a chemically related state. Substances become completely neutral in relation to the environment and do not pose a danger to humans.

However, if the mineral wool is produced by a artisanal method, then the health danger exists. Therefore, it is more advisable to purchase material from trusted manufacturers.

A distinctive feature of mineral insulation is a structure consisting of fibers, which should be solid to ensure thermal insulation. In this regard, special attention should be paid to the cutting process. You can not use scissors for cardboard or fabric for cutting material, or ordinary dining rooms.

On an industrial scale, special machine equipment is used for cutting mineral insulation. Consider how to cut insulation from mineral wool yourself at home.

Often for cutting, mineral wools use a mounting knife. But he has one drawback. a short blade that is not suitable for working with thick insulation plates. In addition, the blade is quickly blurred and requires replacement.

Sometimes a special hacksaw for wood or metal is used, and the craftsmen found how to cut mineral wool at home. a kitchen.pledged knife for cutting Bukhankaa.

How to cut mineral wool in plates and roll: Tool choice

During manufacturing at the factories, the separation of thermal insulation is performed using special inpatient equipment. Professionals engaged in insulation using mineral wool sometimes have in stock and resort to appropriate machines, which at home are usually absent due to unnecessary cost and larger cost compared to other options that allow you to cope with this and number of similar tasks.

When clarifying the optimal tool for yourself, it is necessary to take into account the features of the insulation, which is to be cut, because for thin and thick plates, as well as roller material, it is far from always suitable for the same device, which is why you can encounter the selection in the process of use in the process of use With all kinds of inconveniences and defects. They are able to negatively affect not only the evenness of the blanks obtained during the cut, but also on productivity as a whole, when the cutting will take a significantly more extra time and effort. This is especially noticeable when carrying out with your own hands of sufficiently large.scale work and the absence of appropriate knowledge and skills.

Stationery knife

An accessible tool and an easy.to.use tool with the presence of replaceable blades, the replacement of which, with need, can be easily carried out in cases where the cutting element is dull, which is mainly occurs very often or is damaged. The thin steel of stationery knives copes with the cut of basalt and glass wools, but is ineffective if you need to cut slag plates. The disadvantage of such a tool is the possibility of a cut with its help, the thickness of which does not exceed 50 mm. Resorting to stationary device is optimal in situations where there is a cut of a small amount of thermal insulation material.

Kitchen knife for cutting Bukhankaa

A suitable solution is a tool with the presence of a toothed edge, which helps to reduce the resulting crumbs during the cut of the product, which positively affects the amount of mineral wool waste in case of its use. For convenient cutting of insulation along and down, it is optimal to use a loaf with a blade with a length of about 20-30 cm. The minus of the instrument lies in the high speed with which it is stupid. For this reason, with a large volume of cut mineral wool, it is periodically necessary to perform its re.stripping.

Crossbrushes for metal and wood

The first devices are with the presence of unilateral and bilateral paintings with insignificant and larger in size teeth, so it is possible to easily find the most suitable option for yourself. Crossbrushes for metal cope well with the cut of slag and stone cotton wool, the thickness of which reaches 100 mm. The separation of rolled insulation along the pieces can be made by means of a tool designed to cut wood, which has a long canvas. A significant minus of the use of hacksaw on wood, which is required to take into account, consists in erasing it with teeth of mineral wool fragments, which is why a huge amount of waste is formed in the process of cutting, making its use by far from the best solution.

Special knives

Often such a professional tool is implemented by the manufacturers of thermal insulation material. Depending on the model, the blade can be made of stainless or carbon steel. Typically, the length of the cutting element is in the range of 30-35 cm, and the total length of these knives with a handle, the design of which is designed for a convenient cut at the required angle is about 50 cm.

A tool with a blade of strong stainless steel freely copes with the revealing of mineral wool, regardless of its thickness. In addition, due to the presence of teeth on both sides of the teeth of different sizes, such knives are suitable for cutting insulation with different levels of stiffness. Their blades are freely immersed in slabs and rolls, and a sharp tip allows you to produce even straight, but even a curly cutter without any difficulties.

Knives for cutting mineral wool with a cutting element of carbon steel are highly high.quality and ease of turning, with the need to execute which you have to encounter over time, but need more careful care due to the exposure of the material to the negative effects of corrosion. In order to avoid this, the tool is required to wipe dry and lubricate after each use.

note! The teeth of the chosen knife must correspond to the thickness and density of the insulation, which will be cut.

Cutting machine

The most preferred option for obtaining even and accurate cuts of any complexity. The equipment is highly performance, but has a large cost, which is why its acquisition is appropriate only with a significant amount of upcoming work using mineral wool and the availability of appropriate financial capabilities. If you need to deviate a house of small or medium sizes, you can freely do without a cutting machine, resorting to one of the above tools.

Rules and process of cutting mineral wool with your own hands

The fibrous structure of the insulation leads to penetration into the air during its sawing fine dust, which is capable of getting into the respiratory tract, eyes and skin, causing serious harm to health, due to which work should occur accordingly, with extreme caution and observance of safety measures. First of all, in order to avoid negative consequences, to cut the thermal insulation material is necessary using special clothing and personal protective equipment. They include overalls, headdress, respirator, rubberized gloves and glasses.

Further into the room in which the cut of mineral wool is to be performed, the influx of fresh air should be provided. Cut rolls or plates in a previously well.sharpened cutting element. If the tool has interchangeable blades, then the need for its preparation is excluded. Due to the presence of an acute cutting element in the process of cutting mineral wool, the number of dust formed and entering the air will be reduced to a minimum value.

Important! Regardless of the room or on the street, the insulation occurs, during its execution, the presence of unauthorized persons, as well as animals next to the specified place, should be excluded.

To obtain a high.quality final result, it is better to cut the thermal insulation across the fibers. Separation of mineral wool produced in rolons into strips of the same width is optimal before expanding when it is twisted. The folded material is required to be placed on a stiff flat surface. After that, by means of roulette, you need to determine the optimal length and draw tags in three places in a circle of packaging.

For reliability, the roll should be wrapped with a painting tape with the side opposite from the insulation in the area of ​​the upcoming cuts, which will also avoid when separating a piece of unwinding the remaining material. Removing the packaging must be completed at the end of the department during a circular cut in a folded mineral wool.

The material in the form of plates is required to saw one at a time, and not several pieces at once. It is possible to achieve an even and accurate cut during the preliminary execution of the marking or when applying when carrying out the cutting of a line or other such tools, for example, a construction level or rule that ensures the movement of cutting adaptation along the correct trajectory.

note! In order to avoid tearing under its severity of a cut piece of mineral wool at the end of the saw, it is necessary to hold it by weight.

The cut of mineral wool should occur with a slight excess, which will provide a tight installation of a strip or slab in the required area of ​​the frame. When using roll material, the allowance must be done at 5-10 mm. In the case of the slabs, it should be slightly increased and reach 2 cm. In addition, in order to avoid loss of form of form, which sometimes can occur, it should not be cut in advance, especially in large numbers. It is best to make a cut of insulation gradually in the course of installation work.

If the cut was carried out indoors, then at the end it is necessary to get rid of the resulting fine debris with a vacuum cleaner, and then perform wet cleaning. Mineral wool itself is required to fully protect by means of plaster, a vapor permeable or windproof film. Upon completion of work using thermal insulation, it is necessary to carefully shake out clothes, wash your hands and face, and it is better to take a shower under cool water, so that, if there are fibers on the skin or in the hair, their lag will happen noticeably easier.

Having found out how to cut mineral wool in plates and rolls with your own hands and how to do it better to decide on the most suitable tool for yourself, with which it will be possible to cope with the sawing of the required amount of insulation material in the process of insulation without any difficulties.
