Aluminum Curtain Walls
The newly developed SI (Super Insulation) versions of the FW 50+ and FW 60+ aluminum mullion/transom constructions impress with their trend-setting system details. The new type of isolator design uses innovative materials to reduce energy losses to a minimum. Inward-facing reflective surfaces on the pressure plates also contribute to the outstanding Uf value of up to 0.14 Btu/(hr·ft²·F°), including screw factor. The system achieves this value for the passive house-certified version with a glazing thickness of 48 mm. As part of certification by the Passive House Institute, the system met the passive house comfort criterion of Ucw < 0.14 Btu/(hr·ft²·F°) and was certified as fulfilling the passive house standard with outstanding thermal insulation. This value was calculated and certified by the PHI in accordance with the latest criteria for certifying facade systems, using triple insulating glazing (Ug = 0.12 Btu/(hr·ft²·F°)) with a facade module of 1.20 m x 2.50 m. In addition to the effects of the pressure plate fixings, the impact of the glazing supports has also been taken into account for the first time.
