roller, blind, yourself

Roller blinds. one of the most common design options for a window opening. They serve both decorative and practical functions. This compact and stylish sun protection system fits perfectly into almost any room, reliably protects from the sun’s rays, easy to use, easy to operate.

Blinds are a construction of fabric, a rotating shaft and a special mechanism that winds the fabric on a roller. Unlike the blinds, the canvas is solid, and there are no gaps, due to which, when the curtains are lowered, complete darkness in the room is ensured. Compared to the usual curtains, roller blinds are more compact, weigh less, can roll up into a roll, are easier to clean, since due to special impregnations they do not collect dust and become less dirty..

How to shorten the length

Most often, adjustment of roller blinds along the length is not required, since it is enough just not to unwind the canvas to its full length. But if you are a perfectionist and it is extremely important for you that the blinds are of the right size, then follow these instructions:

  • Hang the curtains, lower the canvas, wait for it to fully unfold and lie down neatly, then take measurements.
  • Mark where you want to crop the canvas.
  • Remove roller blinds, spread them out on a horizontal surface.
  • Remove the weight from the bottom edge.
  • Add an allowance of 40-50 mm to the measured length to create a new “pocket” for the weight.
  • Cut the fabric.
  • Place a canvas underneath the curtain and sew a “pocket” for the weighting agent, insert it.
  • Hang the curtain on the window.

If the length of the “excess” fabric is not too long, then trimming can be dispensed with. It is enough to make a double fold of the fabric, with which you can hide up to 30 cm of fabric. This option for shortening the roller blind is much easier and faster..

If you cannot find blinds of suitable dimensions in any way and do not want to contact the master for individual tailoring, as it is very expensive, then you can solve this problem on your own by cutting the roller blinds to the required size.

How to cut the roller blind to the width

Cutting roller blinds in width is more difficult and requires more care. Preliminary preparation and measurement is done in the same way as described above. After all the measurements are made and the fabric is marked, you can start adjusting the canvas to the desired size. The scheme of work is as follows:

  • Lay out the curtains on a flat surface, disassemble into components (take out the shaft and weighting agent) and unfold the fabric.
  • Cut the shaft to the required width. Please note that its width should be 8-10 mm wider than the width of the canvas. It is better to cut with a hacksaw. After trimming the edges, be sure to sandpaper or file so that there are no chipping on which the fabric can catch..
  • Cut off the weighting agent (it should be 10-15 mm narrower than the roller blinds).
  • Assemble the curtain back into a single structure and hang it on the window.

It should be remembered that cutting the roller blinds will immediately void the warranty on them. Therefore, it is worth starting this operation if there are no other options anymore or the guarantee is not too important for you..

Vertical

Vertical structures contain the following set of parts and elements:

  • chains for lamellae and control cord, lower lamella connection;
  • weights or weighting materials, with the help of which the web of the vertical bar is stretched;
  • sliders, to which individual canvases of the structure are fixed;
  • decorative and bearing cornice.

You will need the following set of tools to shorten the height of vertical curtains:

  • painting knife or scissors;
  • tape measure or ruler, simple pencil;
  • iron for cauterization of the lower cut off part of the product;
  • a lighter or matches to form a tight end of the cut cord;
  • screwdriver with a Phillips bit;
  • fine-toothed saw or hacksaw for working with metal.

Vertical blinds can be shortened in both directions: in width or in height. In the first case, it will be necessary to cut the cornice to the required size, and in the second – each individual canvas, therefore the process is more time consuming than when working in horizontal counterparts.

Instructions for shortening vertical curtains:

  • The dimensions of the window opening are removed, including the level of fastening of the cornice, taking into account the method of its installation. If the curtains must be up to the floor, then 2 cm must be excluded from the measurements, which must be left from the floor to the curtains..
  • In the case of removing the length of the canvases, shortening the eaves is not required. Since the lower part of the lamellas has a more complex design, including pockets for weights, overlays for connecting with plastic chains, therefore, they are cut to the desired height from the upper part.
  • Leaving a small margin for the cuffs, each lamella is cut to the desired length. Remove the plastic tab from the cut area. To preserve the integrity of the canvas, process the edges with a lighter or a hot iron through a newspaper so that the material does not stick to the sole of the appliance.
  • To thread the bent fabric under the lapel, you need to make a hole in the central part of the canvas, into which you drive the eyelet. For gluing the edges of the strip, strong fixation adhesives of the “Moment” type are used..

The described steps are for one lamella. It is necessary to shorten each element of the blind structure by the same length.

To reduce vertical curtains in width, the greatest difficulty will arise with the cornice. For this you need:

  • The aluminum cord and rod are removed from the inside of the curtain rod. The stem washer must be intact, so the cut on this element is made 2-3 cm further. In order not to accidentally cut the cord, you should not completely cut it..
  • The rod is removed from the cornice, after processing with a file, the separated edge is pushed through the washer.
  • At the desired point, the curtain itself is cut off according to preliminary measurements with the rod already installed back.
  • So that the trimmed parts of the structure do not damage other elements, they must be cleaned with a file. Extra hooks are removed from the cornice. Since these parts are pierced with a control cord, you need to cut it with nippers..
  • The washer on the end of the curtain is placed figuratively on the structure, followed by shortening the lace. It is necessary to unscrew the cap fixing it with a screwdriver, cut the rope with scissors to the required length, assemble the eaves structure in the reverse order.

Varieties of products

Modern blinds are very diverse, but still fall into two main groups:

  • products with horizontal stripes;
  • vertical varieties.

Each option consists of a number of components that you will have to work with in order to repair your blinds yourself. If you have to adjust vertical products that need to be reduced in width, then the cornice, the inner rod, the chain and the lamellas themselves must be trimmed..

Horizontal varieties are a little easier to work with. The process of shortening comes down to cutting the strips themselves and the cord on which they are fixed. Let’s take a closer look at all the available methods..

Choosing the type of installation of roller blinds

There are several ways to install roller blinds:

  • fastening to the wall above the window opening;
  • directly to the opening;
  • to the ceiling;
  • window frame or sash.

The choice of fastening depends on the technical features of the room and on the design..

SHADE Specialist Council. Attach roller blinds to a small window without a sill over the opening to the wall. This will visually make the window larger..

Roller blinds are of two types:

  • Open.
  • Closed or boxed.

A standard open-type curtain consists of a rod, or tube, on which the fabric is wound, 2 brackets with plugs and 2 latches with gears.

  • Before starting the installation, open the package and assemble the roller blind: insert the latches with gears into the grooves of the brackets and connect to the bar holding the roller blind.
  • Attach the curtain to the part of the wall or frame where you planned to attach.
  • Gently unwind the canvas, checking whether it lies flat, does not interfere with closing (opening) the window with a handle.
  • Mark with a pencil on the wall (frame, ceiling) where the brackets are attached.
  • Using a level, check if the marks are at the same height, correct if necessary.

SHADE Specialist Council. If, when buying the blinds, the size of the finished product was taken into account, fasten the brackets exactly along its width, if not the finished product, but the canvas covering the window, add 3–3.5 cm to the width of the curtain on each side.

Bracket attachment methods:

  • on self-tapping screws;
  • using double-sided assembly tape;
  • on hook type mounts.

Installation of roller blinds on self-tapping screws is simple and reliable. Its only drawback is the holes that will remain in the wall or in the window frame when you remove the curtains. Mounts with hooks can be used only when installing the blinds directly on the window frame, and the window should not be deaf, since the hook brackets are put on its upper part.

Having chosen the appropriate method of mounting the brackets, temporarily disassemble the roller blind by disconnecting the rod from the canvas. If you decide to install the curtain on self-tapping screws, drill holes in the previously marked places, and then fix the brackets. Insert into each gear latch and close the lid.

Carefully screw the tube with the curtain first into the gear on one bracket, then on the other.

Adjust the length of the chain to raise and lower the belt. Lower the shade to the lowest position and secure the magnets at this level. They will hold the curtain tightly against the window, especially when it is in ventilation mode.

In closed roller blinds, the fabric is inside a box that protects the fabric. Such boxes are made in different colors, from different materials, so it is easy to fit them into the interior..

Use self-tapping screws to mount closed curtains. Remove the decorative plugs from both sides of the box. Place the curtain against the window, then gently lower the canvas, making sure it is flat. If the skylight of the window remains open on either side, adjust the position of the box. Make holes in the wall or frame at the places where the box is attached, then fix the curtain on the self-tapping screws and replace the decorative plugs.

In order for the closed blinds to fit snugly against the window, they are fixed using vertical plastic guides:

  • Wipe clean, dry frame with Degreaser or White Spirit.
  • Remove the protective tape from the tape on the guide strip.
  • Insert the top end of the rail into the groove of the box.
  • Glue the guide strip along the glazing bead of the window frame.
  • Also glue the second guide to the glazing bead on the parallel window sash..

Install the top and bottom chain stops:

  • Raise the curtain so that the lower bar is 5 mm away from the box, and fasten the stopper to the chain located closer to the frame.
  • Fully lower the shade and place the lower stopper on the second chain.

How to remove roller blinds correctly

  • Chain the canvas onto a roll.
  • Take a screwdriver. Sink it through the 3 spring-loaded axis of the plug (1.2) into the body of the plug. Remove the pipe from the bracket (3).
  • Remove the pipe from the bracket (2).

Rules for the carriage of roller blinds

When transporting, roller blinds must be placed in some kind of hard case or, say, a tube, otherwise it can get lost among things or be damaged. We recommend packing mechanisms and small parts separately and placing them side by side..

Is it possible to change the fabric, but leave the mechanism?

If you are tired of the canvas, you are not satisfied with the color, spots have appeared, etc., you do not have to buy a new one with the mechanism. If the mechanism works properly, you can leave it, and replace the blade with another.

How to cut a roller blind

  • Unfold the fabric.
  • Extract 1.2 and 1.3
  • Measure the required size with a pencil and cut the fabric along the mowing line of the marking.Next, you will need to cut the cornice itself.
  • Take a saw for metal and saw off the upper tube at a distance of 7 mm from the edge of the fabric and the weight (1.3), the length of which should be 14 cm shorter than the width of the blade itself.
  • Install the plug into the pipe with a hammer. Do not hit the plug with a hammer without a gasket. Use something at hand.
  • Mount the weight on the lower edge of the web.
  • Roll the fabric evenly and tightly. The chain lock should be in the uppermost position on the winding side of the fabric..

Important: the width of the curtain should be 10 cm greater than the width of the opening when attached above it.

The SHADE company offers a huge selection of roller blinds for installation on plastic windows and balconies. In the presence of special models for the kitchen, nursery.

Reducing the length of horizontal products

Before shortening the horizontal blinds, measure the parameters of the new opening several times. In this process, it is important to avoid mistakes, since it will be difficult to increase the parameters of the canvas, and in some cases it is impossible..

If you need to reduce the height of the canvas, follow these steps:

  • Move the product to the “Open” position. Release the retaining cord at the lowest strip. It can be untied or simply cut off.
  • Pull the rope out to the level you need to reduce the height of the belt.
  • Disconnect any excess louver strips from the structure. When the canvas is adjusted to the required height, secure the cord under the lower lamella. Do this work very carefully, as in the process of removing the strips, you can move the strips you need. To return them to their original position, you will have to tinker..

This completes the reduction of the length of the blinds. To prevent the cord from getting tattered during operation, treat its edges with a lighter flame.

Is it possible?

If the blinds are made of metal or wooden slats, then working with them is more difficult than with fabric or paper counterparts. Then the use of a more complex tool and material handling skills will be required..

Most often, a change in the length of the curtains is required, since factory products are not always sold, the dimensions of which correspond to real windows after repair in an apartment or house (read about the rules for choosing and installing blinds on plastic windows here).

Installation of roller blinds

Perhaps there is no more universal way to design window openings than roller blinds. They decorate the windows of apartments and houses, austere openings of modern business centers and solid office buildings. The way of installing them adds sympathy to this type of curtains. They are installed quickly and do not require any special skills. However, no matter how simple the installation of roller blinds is, it must be performed accurately and taking into account the peculiarities of the fastening systems.

What to do if you need to remove the roller blind?

Having considered in detail the issues of installing fabric roller blinds, it is impossible to pass over in silence the issue of their dismantling. For example, to do the laundry or to hang another kind of curtains. This process will also not give you much trouble..

  • Roll up the roller blind all the way. The fabric should be completely wound around the shaft, or enter the cassette.
  • Use a screwdriver to press on the plug shaft. It will go deeper and the fixation will come off.
  • All that remains is to gently pull out the shaft with the cloth.
  • If you need to remove the brackets, simply unscrew the screws. However, if you want to swap one roller blind for another, then leave the brackets in place. A pipe with a new curtain will fit perfectly into them..
