Description
Steel construction, Aluminium covering- and pressure-strip. Covering-strip with reduced emissivity (ε = 0.1) at the inside. PE-foam insulator in the glazing rebate (0.035 W/(mK)). Plastic glass-carier on stainless steel bolts. Thermally insulated screws. Losses by screws and glass carrier were determined by 3D-thermal flux analysis (PHI). Used Pane: 48 mm (6/16/4/16/6), intersection of the Glass: 14 mm. Used spacer: Swisspacer V. 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.
