The aluminum frame hardware plays a crucial role in the thermal insulation, sound insulation, and sealing of the frame. Aluminum frames tested in laboratories for watertightness, air permeability, sound insulation, wind resistance, and security have specific mechanisms. If you purchase an aluminum frame (e.g., Europa 5500) and the frame manufacturer has used different mechanisms than those specified, none of the test results are valid, meaning you do not know the performance of the frames you purchased. The same applies to the frame gaskets and all other frame components.
Fenestral uses the perimeter hardware (aluminum frame hardware) that locks at up to 18 points, which are used in standard tests, as well as all the components used in them, so you know exactly what you are buying. See exactly the brand and type of perimeter frame hardware we use.
Both the installation and sealing of the frames play a crucial role. Watch a video on frame installation during aluminum frame replacement
