Chamberness. The inner cavity of the window profile is filled with partitions that form chambers. The more cameras in the window profile, the less heat loss and better noise insulation.
The thickness of the partitions. The chambers in the profile are separated by partitions. Partitions are divided into internal and external. The outer walls are thicker than the inner ones. The thicker the partition, the more expensive the window profile and the less heat loss.
Mounting depth (profile width) is the thickness of the profile in the section. The thicker the profile, the less heat loss and better noise insulation.
The maximum thickness of the glass. This parameter determines how thick the glass can be installed in this window profile. The greater the mounting depth, the greater the maximum thickness of the glass. The coefficient of resistance to heat transfer is the most important parameter, in fact, it takes into account all factors and shows how effective the window profile is. The higher this setting, the better.
