Description
Aluminium cladded timber frame (0,11 W/(mK)), insulated by ENERcell (0,06 W/(mK)) and EPS-Foam (0,032 W/(mK)). Q100 = 0,16 m³/(hm) testet at a window with flying mullion Stulpfenster (2,26 * 2,51 m). Pane thickness: 48 mm (4/18/4/18/4), rebate depth: 15 mm, spacer: SWISSPACER Ultimate with polyurethane as secondary seal. At the side-section with handle the temperature factor for the cold climate is not achieved. Never the less, this values are much better than usual.
