Description
Steel facade with exterior aluminum cladding and internal screwing duct. Glass carrier and srew-losses determined by simulation (PHI). PE-foam rebate insulation (0,038 W/(mK)). Pane thickness: 56 mm (8/18/4/18/8), rebate depth: 14 mm, spacer: SWISSPACER Ultimate. The glazing was calculated with a 3 mm secondary seal. As it is often the case that this is thicker, today the calculation is carried out with a 6 mm secondary seal. This leads to a higher glazing edge thermal bridge, which can also be estimated by way of the spacer certificates: www.passivhauskomponenten.org / glazing edge bonds. The higher rates of heat loss can be compensated for by using e. g. improved glazing.
