The cost of manufacturing a new window depends mainly on its size. Therefore, almost every customer has the opportunity to measure the opening and send the data to calculate the preliminary cost.
Of course, for the preliminary measurement is not necessary to adhere to the maximum accuracy. However, if you want to get a reliable value of the window price, you must measure with some rules.
The opening should be measured in width and height in three places. The width is measured at the center, right and left edges. Size is measured in the center, at the top and bottom of the window. In this case, both in width and height, the smaller of the three values obtained will be the final size.
The order of measurement on the width and height of the window will be different. It also depends on the type of opening installed in a new window - with or without quarters.
In openings without a quarter (Fig. 1), the standard documentation provides for the device of gaps for mounting seams width of 15-55 millimeters. However, performing a hole of about 30 mm in most cases is recommended. Therefore, to obtain the size of the window from the measured width of the opening, subtract 60 millimeters (30 mm on each side).
If installing a window into an opening with a quarter (Fig. 2), measure the window's width using the outside dimension of the quarter. The measurement is also made in three places, selecting the smaller value. The window's width should be 20-30 millimeters larger than the outside dimension of the opening. With a greater width, the window can go a quarter too deep, deteriorating the appearance and making it impossible to install a mosquito net. Therefore, you must add 40-60 millimeters to the data obtained when measuring.
When measuring the height of apertures with quarters (Fig. 4), measure from the outside from the top edge of the opening to the sill, while you need to add to the leading edge of the opening 15-20 millimeters. In installing an aperture without a quarter (Fig. 3), it is necessary to subtract 60-80 millimeters from the received height (the size of a standing profile is taken into account).
WHEN DETERMINING THE HEIGHT OF THE FUTURE WINDOW, IT IS NECESSARY TO TAKE INTO ACCOUNT SOME IMPORTANT REQUIREMENTS:
installation of the sill is carried out strictly under the bottom edge of the window frame, which requires observance of the necessary clearance;
installation of the drip molding is carried out precisely to the lower edge of the window frame, and the essential clearance must be observed;
If the sill has an upper quarter, the frame overlap must not exceed 20 mm;
The size of the installation gap in the absence of an upper quarter must be 15-30 mm;
Observance of these requirements will give a relatively accurate value, but a specialist fitter must carry out the final measurement.
Determining the size of the sill and window sill for a layperson is difficult. Therefore, the results obtained are only approximate. Do not be guided by the size of the existing window sill and sill, as the width of the new window can be very different from the old. The determining parameter is the width of the wall.
The sill should protrude from the wall at about 5 millimeters. Such an overhang allows for normal drainage while preventing damage to the sill from falling objects from above. In addition, the sill ledge is recommended so that it does not overlap the radiator by more than half. Thus, to determine the total width of the window sill and the drip molding, subtract the width of the base profile from the width of the wall and add the values of the necessary gaps. The individual width of each element will depend on the distance at which the window will be installed from the outside of the wall.
Repairs in such cases will only help to correct the problem for a short time. The window products should be replaced on time to avoid new or repeated trials. However, if the problem is tiny, it is better to limit the repair without changing the entire PVC system. Do not rush to change the window because you want to change the interior. Modern window decoration products such as window linings and lamination will help you update a long-used profile.
