Curtain wall system
forster thermfix® vario Hi 45 mm


Component id: 0963cw03
Manufacturer: Forster Profilsysteme AG
Category: Curtain Wall System
Material: Steel / Aluminium
UW: 0.80 W/(m2 K)
Efficiency class: phA
Spacer: SWISSPACER Ultimate
Climate zones: Cool, temperate
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.
