How to determine the size of roller blinds for windows?

Curtains classic cut always relevant. But they are not always suitable for the interior of the room or not for everyone. In such a situation, the only correct way is roller blinds. This type of curtain is a piece of fabric that is fixed on top of the window on the shaft. Basically, it spins from top to bottom. The main lifting mechanisms in such products are mechanical and automatic. An automatic lift is more convenient than a mechanical lift, but unfortunately it is much more expensive.

Roller blinds are of two main types:

• closed;
• open.

The mechanism of open rolets is much simpler, since it does not have a shaft on top that protects the fabric. They are much cheaper, but they get dirty more often. Closed curtains have a protective shaft and most often they are equipped with an automatic lifting mechanism. The cost of roller blinds depends on the quality of their components.In addition, this type of product may differ in color and type. It is very difficult to make roleta by yourself and therefore it is better to order them, taking into account the size of your window.

They can be multi-colored or solid. The materials from which they are made, the most different. In a separate group are the curtains, which are called "Day-night." They consist of two strips of cloth. In the closed state, they look like a single unit.

When it comes to replacing old windows with new windows, the question of decorative components, or rather curtains or blinds, involuntarily arises. With the advent of plastic windows, it has become fashionable to use roller blinds in the interior. They are much more practical and modern. It is necessary to choose roller blinds for your room based on a number of criteria:

• Do you have a sunny side?
• what density fabric is required;
• type of attachment - on the sash, window frame, on the wall, in the slope or ceiling;
• open or closed system;
• choice of fabric color.

Fabrics for roller blinds on the density of the material can be divided into four groups:

• First group - it is light translucent fabrics. They do not give a significant blackout, but play a more decorative function. These fabrics should be used when it is necessary to achieve the effect of a slight darkening and use the product only as an element of window design. Translucent fabrics are produced mainly with a pattern.

• Second group - Thick fabrics that provide a significant darkening in the room. Can be both with drawing, and monophonic. They should be used in moderate sun. They have both a decorative function and sun protection.

• Third group - these are very dense fabrics. Products should be used in case of very strong sun, for example, if you have a south side or a large window. In addition to the sun protection function, they are also used as a decorative element of the window design. These fabrics are with a pattern and monophonic.

• Fourth group - fabrics blackout, or full blackout. Happen with drawing and monophonic. With a rolled curtain made of this fabric, even in the middle of the day when the sun is shining, you will have total darkness in your room.

With fabrics were defined. Now you need to figure out how to fix the roller blind.If you already have the usual curtains or tulle, then the best option for fastening the blinds is on the sash or on the window frame. If there are several sashes - two, three or more, such as, for example, on the balcony, it is better to install a curtain on each sash separately. It will be more convenient.

Although the first option of mounting on the sash or window frame can also be considered. For example, in the kitchen instead of the usual tulle, because it is constantly getting dirty, you can use a closed system of roller blinds. The shaft with the cloth is covered with an aluminum box in the color of the window, along the edges aluminum guides are also placed in the color of the window. They serve to fix the fabric.

Due to the fact that the product with a closed system is mounted directly on the window, it is completely removed from the main sources of pollution, such as stoves and sinks. That is why the product will last a long time even without additional cleaning.

To select and buy suitable roller blinds, it is necessary to measure the window correctly. For this you need to find out the following parameters:

• Width. For the correct measurement, the width is indicated from the joint of the bead to the frame on the one hand, and the joint of the bead to the frame on the other hand - this will be the width of the fabric. In roller shutters with an open-type mechanism, the overall width of the roller shutter will be 38 mm wider than the width of the fabric due to the upper side mounting mounts. Rolette measured in this way completely closes the glass unit and window bead, which ensures maximum overlap of the opening.
• Height. For the correct measurement of fabric roller blinds, the size from the bead joint to the frame from the bottom to the bead joint to the frame from the top is indicated. The size of the mechanism of roller shutters is added to the height of the fabric and is about 70 mm (36 mm of roller shutters +34 mm indent from the bottom).

It is worth paying attention to the depth of the roller shutter mechanism, which is approximately 36 mm. It is necessary to consider the distance from the edge of the roller shutter mechanism to the slope. From this distance depends on the opening angle of the window.

In order to correctly measure the width of the flat-guided rolling role, it is necessary to measure the following parameters:

1. The width of the opening at the joint of the bead to the glass (fabric width).
2. The width of the edge of the bead (box width).
3. The depth of the bead.It should be at least 10 mm, since the fabric should not touch the glass.
4. The width of the bead. It must be greater than 10 mm, since the minimum width of double-sided tape for guides is 9 mm.
5. Height. For the correct measurement of the fabric of the roller shutter, the size from the bead joint to the frame from the bottom to the bead joint to the frame from the top is indicated.

It is worth paying attention to the depth of the box roller shutters, which should be 36 mm and a height of 70 mm. It is necessary to take into account the distance from the edge of the roller shutter mechanism in the slope, since the opening angle of the window depends on this distance.

To measure the roll-up curtains with U-shaped guides, it is first necessary to find out the width. For the correct measurement, the width from the joint of the bead to the frame is indicated on the one hand, and to the joint of the bead and the frame on the other hand - this will be the width of the shutter along the edge of the guides. The overall width of the shutters will be 20 mm wider than the guides.

For the correct measurement of the height of the fabric roller blinds, the size from the joint between the bead and the frame from the bottom to the joint between the bead and the frame from the top is indicated. The distance from the slope on top of the window frame to the joint between the glazing bead and the frame (for blind windows) must be at least 35 mm.

Designers prefer to use roller blinds in a modern home interior. They are especially suitable for residential premises where active people live with a modern outlook on life. Their advantage is that you can choose any pattern, design and quality fabric for manufacturing.
