Curtain wall system
Lara GF 50 - PH

Component id: 0156cw03

Description: Timber construction, Aluminium covering- and pressure-strip. PE-foam insulator in the glazing rebate (0.035 W/(mK)). Plastic glass-carier on stainless steel screws. Used Pane: 48 mm (6/16/4/16/6), intersection of the Glass: 14 mm. The screw-losses were carried out by 3D-thermal flux simulation (PHI), for the glass-carrier losses, the default-vaues according to the certification criteria were taken into account. 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: / glazing edge bonds. The higher rates of heat loss can be compensated for by using e. g. improved glazing.
