WINDOWS DO NOT MOUNT IN FOAM. It has a sealing role and is applied between the window sill and the wall. Do not accept the installation of windows only in foam, as there is a risk that they will bend and even fall. It is not recommended to open and close the window less than two hours after foam insulation. After 48 hours after foam sealing the windows, the surplus is removed and the interior / exterior masonry can be finished. If the foam is exposed, there is a risk that it will absorb the water from the precipitation and facilitate the appearance of the mould. The protective sheet of PVC profiles will be removed only after finishing the walls.

Barrier windows and doors are designed to withstand the extreme weather. The quality of the assembly made of PVC joinery and with insulated glass Barrier can withstand the hottest summers and the strongest sun, as well as the most severe winters, storms and even hail.

The windows are fixed to the wall with screws and special fasteners. The fixing elements vary depending on the type of material from which the wall is built (brick, concrete, BCA) on which the window will be mounted. The mounting team will use the fasteners suitable for the wall type.

The use of PVC profiles is not recommended in large joints where, besides the fact that we have a large expansion coefficient, problems may arise when joining between the heel and the wall, between the heel and the movable sheet, even bending of profiles. The weight of these large joints must also be taken into account. If in aluminium, which is the easiest, the joint systems at the corners are mechanical, in PVC, the joint is by hot melting, but the steel reinforcement cannot be welded.

Also, it is not recommended to use PVC joinery profiles in the case of exterior doors for heavy traffic, interior doors, or glazed interior compartments. Choosing the material variant is quite complicated; there are special cases, so we recommend the advice of a specialist.

For PVC windows, the service life is 10 years. For aluminium windows, the service life is 15 years.
