How to measure roller blinds on plastic windows

Blinds - the most compact of the existing. They allow you to arrange a window opening with a minimum of funds, at the same time reliably closing the room from prying eyes, sunlight. Some companies in the manufacture of blinds offer customers to make a discount if they themselves measure the size of the window.

Before buying roller blinds, it is necessary to measure the dimensions of the windows

Rules for measuring roller blinds

The window is measured in closed form with a conventional tape measure up to a millimeter. The height of the curtains for the deaf leaf should be correlated with the height of the opening transom. The lower edges of the fabric guides should be on the same level.

For the manufacture of blinds pre-determine where to install the mount:

  • on the opening outside;

    Sizes of roller blinds for installation outside the window opening

    Measurement of rolled curtains for installation on an aperture

  • inside the opening;

    Measurement of roller blinds when placed inside a window opening

    When measuring takes into account the irregularities of the window opening

  • on each transom separately.

    Measurement of curtains on different plastic window leaves

    It is necessary to compare the height of the curtains on the deaf and opening doors.

Measurement is carried out by two parameters: width, height. Having thought how to measure roller blinds on plastic windows, take half an hour or an hour, prepare a tape measure, a notebook and a pen to record the results. Think about what design you want to install.

Important! Zebra blinds (they are also called day-night) require more space in depth (0.3-0.5 cm).

Design of plastic windows with day-night blinds

Day-night blinds consist of two strips of fabric; when closed, they look like a solid canvas.

The width of the roll-curtains corresponds to the width of the glass with regard to the side bead (this is an element that securely fixes the glass in the frame, it can be ironed or rectangular in shape), plus 0.1 cm on each side.

Measuring the width of the open curtain

For open-type roller blinds, the width is measured between the outer edges of the bead

When determining the size, it is necessary to take into account whether the fastening of the roleta (rod, rotation mechanism, end caps and fasteners) will not rest against the hinges or slopes.

The opening angle of the sash window with different types of roller blinds

Cassette curtains come in two sizes, UNI1 and UNI2, the first of which has smaller dimensions and is designed to be installed on the opening window sash

The height is measured from the upper edge of the leaf to the bottom of the leaf; moreover, if the bead has a rounded shape, then it should overlap the border of the frame on the glass side by 2-5 mm.

If the frame opens, the length must be reduced by 5-7 mm from the bottom. For a blind transom, height is measured from the upper to the lower bead plus 0.5 cm.

The height is measured between the upper edge of the upper bead and the lower edge of the lower bead.

What errors occur during measurement?

Instructions on how to measure curtains are needed in order to avoid common mistakes. Many people think that it is enough to measure the frame across and along, but the windows are not the same throughout their area, so you need to make three measurements at different distances. Specify in the order the smallest resulting value. With an excess of width / length, the curtain may not fit in the opening.

Important! It is necessary to take into account the dimensions of the roleta itself, which holds the curtain.

Roleta is open and closed. Open-type structures are cheaper, but they get dirty quickly. Closed mechanisms are more expensive, but much more convenient.

Types of roller blinds for plastic windows

Roller blinds are of two types - open (in the photo on the left) and closed (on the right)

Mechanical or automatic control is encountered. The overall width of the roller blind is 0.3-0.5 cm larger than the size of the curtain itself due to the mounting fasteners / caps on the edges. If you do not take into account the difference, the canvas can go beyond the frame - it will have to be trimmed during installation.

Electric curtain for PVC windows

When choosing curtains with electric drive, it is better to give preference to compact models, the dimensions of which are slightly more than manual counterparts

The depth of the mechanism is 3.5-4 cm (the design and its dimensions need to be clarified with the manufacturer). Due to differences in the methods of attachment, preliminary measurements are recommended to entrust professionals who know the subtleties of various devices for mounting and managing such curtains.

Measuring the height of the roll-up mechanism

It depends on the depth of the mechanism whether the window sash can open normally.

Sometimes roller blinds are installed so that they cover only the glass itself inside the frame. In this case, the design is attached exclusively to the frame with a rectangular bead.

Curtains with guides are good because they completely block sunlight

When this element has a rounded shape, the curtains do a little more, are placed higher in the window opening. Large blinds are placed outside, the shutter is attached to the wall or ceiling.

Pay attention to the location of the handles for opening the frame! A roll in the clear should not block access to them.

It is more practical to arrange the control system so that the cord does not collide with the handle.

If the curtain, when used, will touch something, then there is a high probability of tearing the structure from its place. The lower edge of the guide, hitting the window sill, get dirty, wrinkled.

Features curtains with guides

To keep the blinds flat, and there are no gaps around the edges, use guides - roller blinds look neat, last longer, do not warp. Understanding how to measure the window for roller blinds with guides, you must consider the following features:

  • the depth of the bead should be sufficient so that the fabric does not touch the glass, which is about 10 mm;

    The depth of the bead on the plastic window

    It depends on the depth of the bead which system of curtains fits best.

  • the width of the window opening is measured between the joints of the frame edge with a double-glazed window - this is the size of the canvas;

    Web width is measured between the edges of the side glazing beads.

  • the width of the decorative box is equal to the size from one edge of the bead to the other;
  • consider the size of the bead - with a width of less than 10 mm there is not enough space for mounting the guides on a special tape (9 mm);

    Measurement is performed with an accuracy of 1 mm! Use only metal tape measures or rulers.

  • the height of the finished curtains will be equal to the height from the joint of the bead with the frame at the bottom and top.

    The height of the curtain with flat guides is measured between the edge of the upper bead and the edge of the bottom

Important! When deciding exactly how to position the curtain with guides, keep in mind that the height of the rolette box cannot be less than 7 cm at a depth of 36 mm

Closed roller blinds on a plastic window

Guides securely fix the curtain fabric, not allowing it to sag and stick to the window

Closed rolettes are used to measure the width of the fabric from the joint between the bead and the frame, and not with the glass. The width of the mechanism of the roller blind itself is 20 mm larger than this value. The measured size includes the width of the guides of the U-shaped. The mechanisms of the closed type use exactly such constructions, which adds 3-5 mm on each side.

Important! The edge of the control mechanism must be at some distance from the slope, so that it can be opened slightly.

If the window slope passes very close to the transom, the curtain mechanism may interfere with the full opening of the sash.

The height of the blind with guides is determined by the joints of the frame and bead from top to bottom.For windows that do not open, the distance from the slope to the junction of the frame with the glass should be at least 45 mm - this provides space for mounting the shutters.

Professional help

Practice shows that the standard windows when measuring are not rectangular, their size varies slightly at different points of fixation. For larger sizes, roller blinds are needed specifically for panoramic glazing, the measurement of which is better to be entrusted to a specialist. For large-scale structures, it is necessary to take into account several attachment points, to take measurements several times.

For non-standard window openings, only a specialist can determine the size measurement algorithm. For options with a rounded upper part, it will be difficult to make blinds due to the peculiarities of fixing blinds. Measurements include the definition of the parameters of the circle, the choice of method of attachment - this is impossible to do without knowing exactly what exactly the tools and technologies the company has.
