How is installation (installation) of metal-plastic windows?
27.01.2020
Installation of plastic products is an integral part of the purchase and is as important a link in the process as manufacturing. A quality window remains so only after its proper installation.
Questions that arise during the installation of windows:
- building physics: climatic loads on the window, thermal and humidity conditions;
- distribution and perception of wind loads on the structure;
- aesthetics of the mounted product in the exterior and interior;
- window mounting diagram.
Some rules for installing metal-plastic windows:
- Installation should be carried out by specialized installation teams who have a license to carry out installation work.
- At the request of the customer, a standard instruction for the installation of products made of PVC profiles must be provided.
- When installing a window, the following conditions must be taken into account: the sealing of the mounting gaps between the window and the wall must be dense, uniform, withstand climatic loads outside and inside the room; the operational properties of the junction units must correspond to the highest values of the norms that are established in the current standards (SNiP);sealing the seams from the inside must be denser than the outside; the scheme of the adjacency nodes must ensure the timely drainage of rainwater and condensation outwards. It is forbidden to penetrate moisture into the wall; adjacency units should not contribute to the formation of cold bridges, and to fogging of windows on internal surfaces; when calculating installation gaps, it is necessary to take into account the thermal expansions of the structure.
- It is forbidden to use sealants, glue and foam to fasten the window.
- The distance between the fasteners when installing a white metal-plastic window should not be more than 70 cm, in the color profile not more than 60 cm.
- To fill the seams between the wall and the frame, polyurethane foam cords, foam insulation and other materials are used that can ensure the performance characteristics of the seam.
- To transfer loads from the structure to the wall, pads made of different polymeric materials or wooden are used.
- It is not recommended to paint over the seams.
- When docking a window with balcony doors, the seam between them should be smooth and exclude blowing. When docking, a special profile is used.
- These recommendations do not apply to the installation of stained glass windows, bay windows and elements of continuous glazing of openings.
