The products used came from Alumilex’s 2060 series and 120 series, specifically, tilt-and-turn windows and lift-and-slide doors that are highly energy-efficient and easy to use.
“We are always stretching the limit of performance and sizes of windows and doors, and so for this project we decided to go to the extreme with our fabrication and solution and sizes,” says Tony Benzo of Alumilex.
To reduce thermal transmission, Alumilex ensured every sash and frame member consists of heavy aluminum extrusions assembled into a single member with two fiberglass-reinforced continuous polyamide thermal breaks. Crimping the polyamide bars in the internal and external sections provides rigidity; and since both aluminum and polyamide have similar expansion and contraction properties, the structural integrity remains constant under all weather conditions. Moreover, all joinery is executed using right-angle die-cast cleats for faithful geometry. The critical task of sealing the mobile sash to the fixed frame was achieved by using EPDM prime seals and a secondary rebate gasket that prevents any residual infiltration. The glazing unit is also sealed with double EPDM continuous compression seals for maximum air- and water-tightness.
