Low profile, adjustable stainless hinges (AHT) are complimentary of the slim extrusions, yet strong enough to handle a 40″ wide by 108″ tall panel.
In order to align with modern architecture, frames are butt joined instead of mitered. In order to achieve this feature and maintain strength, we needed an exceptional corner key. The wall thickness exceeds 5/16″ in most locations and penetrates 4-1/4″.
Aluminum is thermally stable in that it does not swell or shrink when the temperature or humidity levels change. Very little energy is lost through the frame material but in the case of wood and vinyl, energy is lost through the frame and vent seams after years of expansion and contraction.

For over 10 years, Fleetwood has incorporated polyamide thermal struts on all new products, resulting in a more attractive design and innovative shapes.
