Various types of mounting
There are many ways to install windows, but experts say that there are two basic ones: correct and incorrect. This is obviously an industry joke, but it shows how important an element of window replacement is installation. Even the best product will not work properly if it is not properly integrated into the building wall. The differences relate to special-purpose windows. We install standard windows differently, differently energy-saving, and yet differently anti-burglary windows.
Most users choose to install standard windows that meet their requirements sufficiently. The method of installation is adjusted to the type and thickness of the wall, and a detailed design is prepared before starting work. In simplified terms, it can be assumed that in single-layer walls, the window is inserted in half its width, in two-layer walls at the outer edge, and in three-layer walls at the insulation level. Anchors or dowels are used to fix the window. The assemblers decide about the choice of mounting. The first solution is used in the case of smaller windows, and the second one, which ensures greater rigidity of the structure, for larger windows.
It is very important to properly prepare the wall for installation. The surface of the jamb, i.e. the window opening, should be carefully cleaned to remove any loose pieces of wall and other debris. The window itself is inserted in such a way that the distance from the wall at the top and on the sides is the same. At the bottom, there is more space for a window sill or other type of window sill. The window frame is fixed with wedges and it is time to install the frame, for which the previously mentioned dowels or anchors are used. After installing the frame, the space between the window and the wall is insulated. Correct sealing is crucial for meeting the insulation parameters of the window.
Energy-efficient windows require a slightly different installation. In their case, it is very important to seal the frame more carefully in order to eliminate thermal bridges through which warm air escapes. Before installation, the surface of the opening is carefully leveled, and three layers of insulation are used for sealing. The first outer layer of the vapor-permeable tape protects the insulation against weather conditions. The middle layer, most often polyurethane foam, is located between the window and the frame. The third inner layer is a vapor barrier foil that protects the foam against moisture. This type of installation is called warm installation for a reason, because it allows for high energy savings .
Installation of anti-burglary windows
The method of installing anti-burglary windows is still different. In order to take full advantage of their properties, they should be installed in accordance with the strict European standard EN-V 1627-30. It includes parameters such as the type and size of the dowels, the distance between them and the depth of the anchors. If the installation conditions are not met, the window will not meet the safety certificate. Therefore, for the installation of anti- burglary windows , it is necessary to hire an assembly team recommended by the manufacturer, who will issue an appropriate guarantee document after the work is done .
