Than Saw Doors For Doors

Sooner or later you have to change the interior doors. The procedure is not so complicated that it is necessary to hire a specialist. If you have at least some skills in handling the saw, level and plumb, you can twist a few screws. do it yourself. When replacing, before installing the interior door, the old one must be dismantled. And there are features too. About all the intricacies. in the photo and video with detailed instructions.

Interior doors are not only different in design, but also make them from different materials

Interior doors are made of different materials. over, the material and the door leaf and frame are different. Door leaf happens:

  • From fiberboard. These are the cheapest doors. They are a wooden frame to which a laminated fiberboard is attached. Differ in low sound insulation, are afraid of the increased humidity, are easily damaged.
  • From MDF. They cost much more, but the quality characteristics are much higher. They are better in sound insulation, are not afraid of humidity, stronger and more durable.
  • Wood. The most expensive doors. They are made from different types of wood. from pine to oak or more exotic species.

Door frames are also made of the same materials. The worst choice is the boxes from fiberboard, they even bend under their weight, and hanging the door leaf on them is a real meal. So try to take either MDF or wooden. There is another material: laminated wood. The good thing is that you do not need to process and paint, but the service life depends on the quality of the film.

Dimensions and equipment

Interior doors are available in standard sizes, it is only a pity that the standards in different countries are different. For example, in our country, swing doors are made 600. 900 mm wide in increments of 100 mm. In some EU countries, the rules are the same. in Germany, Italy and Spain. In France, others are standard. Here the narrowest doors are 690 mm and further in increments of 100 mm.

Is the difference so important? If you want to change only the door leaf without a box, it is important. you have to choose from your segment or completely change along with the box. Interior doors of such a standard, as in our country, the choice is much greater, as in France. many times less.

Recommended door leaf width for different door frame sizes

How wide the doors are needed depends on where you are going to put them. If we talk about standards, the following values ​​are recommended:

  • in the living room width from 60 to 120 cm, height 2 m;
  • Bathroom. width from 60 cm, height 1.9-2 m;
  • in the kitchen, the width of the door leaf is at least 70 cm, the height is 2 m.

If, when replacing the door, it is decided to make the opening larger / smaller, permission is not necessary, but it is necessary to remain within the limits set for each room.

How to determine which width to buy doors? Measure the door leaf that is available and you will know what you need. If there are no doors, find the bottleneck in the opening, measuring it, you can find out how wide the door block is. This is a door leaf door frame. So the outer dimensions of the door frame must be less than the measured value. For example, if you get 780 mm, look for a block with parameters of 700 mm. Wider in this opening can not be inserted.

The most complete interior door. with a box, extensions and platbands

When choosing a door, pay attention to the equipment. There are three types of assembly:

  • Door leaf. Buy a box separately.
  • Doors with a box. Everything is complete, but the box is in the form of individual boards. We’ll have to cut corners and connect, hang the loops on their own.
  • Door block. These are doors ready for installation. the box is assembled, hinges are hung. Only trim the sidewalls in height, align and fasten evenly.

With the same quality of door leaf, the prices of these sets differ significantly. But the difference in time that you spend on installation is decent.

Step-by-step installation of interior doors

In general, there are many subtleties. We will try to describe and illustrate the most common moments in a photo or video material.

Step 1: Assembling the door frame

If you did not buy the door unit in the assembly, the first step is to assemble the door frame. It consists of two long racks located on the sides, and one shorter bar at the top. the lintel.

Connection Methods

There are at least two options for how to connect these bars together:

    Below 45 °. The option is the most correct from the point of view of aesthetics, but the most difficult to perform. High precision cuts are needed. so that there are no gaps. With dexterity, you can also saw off using a carpenter’s miter, but you need to do it carefully. The second point. if you saw a laminated material with a hacksaw, chips remain on it. The way out is to use a well-ground tool.

One way to connect a door frame

How to connect a door frame

Regardless of which way you are going to connect the elements of the door frame, the first thing they do is wash down the racks and lintels on one side. Then they are put in a box on the floor, checking the connection. Next, you need to determine the height of the side parts of the door frame.

Determine the size

When folded, the required length is measured on the inside of the rack. The racks do not always make the same: the floor is often uneven and this must be taken into account. To do this, take the level and check how flat the floor is. If it is perfectly flat, the racks will be the same. If there is a deviation, it must be taken into account: make one of the racks longer. Usually this is a few millimeters, but this is enough to warp the door.

When calculating the height, note that the racks should be 1-2 cm longer than the door leaf (taking into account the cuts). A gap of 1 cm is made under the door, if it is not intended to lay a mat under. If there is a rug / carpet / carpet, it is better to do more. Do not be afraid to leave gaps. They are necessary for normal ventilation in the room. Once again, we pay attention: the height is measured along the inside of the door frame. from the bottom edge to the saw cut. Having cut off, try on racks in a doorway.

Clearance when installing interior doors

Now it is necessary to saw off the lintel along the length and, if necessary, saw it on the other side (if the joint is at 45 °). The length of the lintel should be such that when folded, the distance between the uprights is greater than the width of the door leaf. The minimum clearance is 7 mm, but often do more. 7-8 mm are distributed as follows: 2 mm. on loops, and 2.5-3 mm on compensation clearances. Any interior doors. MDF, fiberboard, wood. depending on humidity change their dimensions. To take into account these changes and gaps are required. And 5-6 mm. this is not always enough, especially in wet rooms. For a bath, leave a little more for sure, otherwise they may be difficult to open when humidity is high.

So, we decided on the minimum gaps when installing interior doors:

  • on loops. 5-6 mm;
  • at the top, bottom and sides. 3 mm;
  • bottom. 1-2 cm.

After you cut off all the parts and made the cuts, fold the box on the floor. If you notice flaws in the docking somewhere, fix it with sandpaper attached to the bar. The more accurate the match, the smaller the gap.


Regardless of the material of the box and the method of connection, holes are pre-drilled for fasteners. so that the material does not tear. The diameter of the drill is 1 mm less than the diameter of the self-tapping screw.

They fold the box, set the angles to 90 °. Holding the rack and lintel in this position, drill holes are drilled. If there is an assistant, he can hold. If you work alone, temporarily fasten the box correctly exposed with two transverse bars. closer to the top and bottom. This will help not to make a mistake and make the right connection.

How to connect the door frame in the corners

If connected at an angle of 45 °, three holes are made on each side. Two on top. a centimeter back from the edge, and one on the side. in the center. Total for each connection requires three screws. The installation direction of the screws is perpendicular to the connection line.

How to connect a door frame

If connected at 90 °, everything is simpler. Drill two holes from above, directing the drill exactly down.

Step 2: Inserting Loops

Most often, 2 hinges are installed on the interior doors, but 3 can also be installed. They are placed stepping back 200-250 mm from the edge of the door leaf. If the box and door leaf are made of wood, choose a place so that there are no knots. First fasten the hinges to the door leaf. The procedure is as follows:

  • We apply loops to the selected places, outline the contours. The easiest way to do this is with a finely honed pencil, but experts advise. with a knife blade. This is more accurate and smaller gaps remain.
  • If there is a milling cutter, they work, if not, they take a chisel and select the material for the thickness of the loop. You do not need to do more sampling, only by the thickness of the metal.
  • A loop is installed in the prepared recess. Its plane should be flush with the surface of the canvas.
  • The exposed loop is fixed with self-tapping screws.

Having fixed two hinges, they put the door leaf into the assembled box, set the correct gaps: from the hinge side. 5-6 mm, 3 mm from the opposite side and from above. Having exposed these gaps, the canvas is fixed with wedges. Expose exactly in the horizontal and vertical plane (you can use the pads, if necessary).

After exposure mark out the location of the mating parts of the loops. Sometimes it’s more convenient to remove the already installed loop, and then install it in place. By marking, they also make a notch. Depth. so that the hinge surface is flush with the surface of the door frame.

The door hinge is described in detail in the video.

Step 3: Install the door frame

The assembled box must be correctly inserted into the opening. This is a very responsible task. Before you install the interior door, knock down everything that can fall off in the opening. If the wall is too loose, the surface is treated with a deep penetration primer with an astringent effect. If there are too large holes, they are covered with plaster, very large protrusions are squeezed. In the prepared opening, it is easier to insert the interior door. If this is your first time doing it yourself, make your work easier.

Exposed box without door leaf. It is oriented strictly vertically. Verticality is checked not only by the level, but also by a plumb line. The level often gives an error, therefore it is more reliable to check with a plumb line.

Check the inserted interior door using a plumb line.

To prevent the box from distorting during installation, yet on the floor, install temporary struts, in the corners. cuts, which give a high degree of rigidity. In order for the doors to open, they are inserted in the same plane with the wall. Only in this way will it open completely. If the wall is uneven, put the box not on the wall, but vertically. Otherwise, there will be problems opening or closing the door.

How to insert an interior door with your own hands. in the same plane with the wall

After the position is selected, you can fix. They do this with the help of mounting wedges. triangular wooden or plastic bars. First, wedges are placed on both sides of the lintel. the cross-member, then above the uprights. Thus, the position of the box relative to the doorway is selected and fixed. Next, the verticality of the racks is checked again. They are checked in two planes. so that they are not inclined forward or backward.

How to put an interior door with your own hands: wedge the box

Then set the wedges below, then after about 50-60 cm, checking that the racks are exactly standing level. The cross bar is also wedged in the middle. Check if the box elements are bent somewhere, if necessary, correct. You can begin to mount.

Step 4: Securing the box to the doorway

There are also two mounting methods: right through to the wall and mounting plates. If the wall allows, and you are not afraid of the fastener caps in the box, you can attach it through and through. It is reliable.

To install the interior doors, it is quite enough to screw two self-tapping screws into the cutouts under the hinges and, on the other hand, under the plate of the mating part of the lock. Additional holes are drilled in the cut-out recesses. They are made so as not to get into the holes for attaching loops or mates. Make sure that the head of the screws is recessed and does not interfere with the installation of hinges and pads.

Installation of interior doors according to this scheme is shown in the video. There are several interesting nuances about setting the door frame.

If such a quantity of fasteners seems unreliable, they drill through, and cover the holes with decorative washers matched to the tone. Or there is also a special MDF molding with removable trims. Fasteners are installed in the prepared groove, and then closed with a bar.

Special boxes for interior doors made of MDF

The second method. secret, fasteners while not visible. First, mounting plates are attached to the back of the box. In principle, it can be used for drywall, but there are special ones that are thicker, although drywall is enough for installing interior doors.

Step 5: Foaming

After all the gaps are set and wedges are installed, the cracks between the box and the wall are filled with mounting foam. For its best polymerization, the wall is wetted with water from a spray bottle. After squeezing the foam, filling no more than 2/3. Too much foam can cause the box to blow out. Therefore, do not overdo it.

Fill the gap with no more than 2/3

To ensure that the doors do not warp the foam, put spacers. But if you do not overdo it with foam, nothing should happen.

Spacers for fixing the box. with this installation of the interior door, the box should stand straight

After the foam is polymerized (the exact time is indicated on the cylinder), the spacers are removed, the door leaf is hung and the door is checked. Further there are finishing works: slopes and platbands, if necessary. additional materials.

Do you know how to install the interior door with your own hands. There is nothing super complicated, but we tried to describe the main nuances. There is a lot of usefulness in the video. these are recommendations from practitioners.
