Filling the joints between the window and the design of the house affects the average coefficient of internal heat. Violation of technology can lead to the formation of unwanted condensate, mold and other problems.

The letter of the Ministry of Regional Development contains important decisions regarding various norms in construction. The installation of high -quality windows must be made in the construction estimate.
Windows, thanks to their design and requirements, are quite complicated, so their mechanical fastening is extremely important. This is achieved using special bolts. The seal on the inside is used for tightness from the penetration of water and air. Silicone sealants are used. The material should be elastic.
Polyurethane and mineral wool can be used for thermal insulation. From water from the outside protects a special seal. Only an experienced company with qualified specialists and quality materials can give a good guarantee for windows. With an independent installation of the window, you have no rights to complaints if the windows are damaged.
