We make the correct measurement before installing plastic windows.

Before installing plastic windows, it is necessary to carry out a number of mandatory procedures.

The first measurement of the opening for the window construction.

This process must be approached very responsibly. Indeed, as a result of not correct measurement, the window profile can bend or crack.
How to make a measurement window opening?
Accuracy of measurements should match up to a millimeter and taking into account all distortions and defects of the opening.
If errors are made during the measurement, and the design does not coincide with the required size, then at best, the slots are masked with polystyrene or slopes are increased, of course, this is costly both in time and money.

The main requirement when measuring the window opening.

The window frame should not rest against the opening (the gap between the frame and the unit is called assembly and is intended for possible natural deformation of the structure. According to technical standards, this gap should be from 20 to 50 mm. The measurement is performed both inside and outside the room.) Window measurement performed on vectors in three positions. The smallest figure is the basis for the dimensions of the future design.
