Description of the construction:
1st layer: VIPs in polystyrene
2nd layer: conventional insulation
The passive house in Bersenbrück was completely insulated with vacuum insulation panels set in polystyrene. The VIPs are 20 mm thick and encased by 20 mm thick WLG 035 polystyrene on each side. A second, 80 mm thick, layer of insulation was also mounted to minimize any joint porosity or thermal bridge effects. The target specification of 0.15 W/(m²K) was therefore achieved with a theoretical average U-value of 0.147 W/(m²K). Thermographic images taken of the building before and after the second layer of insulation was mounted clearly show that the initial thermal bridges in the joint areas can be reduced.
