Warm profile.
To create building structures, aluminum has been used for many decades (60 years), but for glazing windows in residential buildings it began to be used relatively recently. The reason is that this material has a significant drawback — high thermal conductivity. Structures made of aluminum freeze in frosty weather through. Therefore, in the production of windows for heated rooms, an integral aluminum profile is used, in which there is a thermal -insulating insert of polyamide reinforced with fiberglass between two aluminum profiles. Professionals call such a liner a thermomust or thermal extension, and a multi -chamber aluminum profile is “warm”. The use of thermal clads can significantly increase heat and sound insulating characteristics of the profile. Warm profile can have up to seven chambers — thus, the width of the thermal discharge increases.
