Vacupor RP-B2-S were laminated with a building protective mat
The effective U-value of a VIP panel depends on the VIP type and size (cf.
Fig.

). Since the thermal resistance of VIP is high even for a small panel
thickness, special care has to be taken to avoid thermal bridges in constructions.
The VIP itself acts as a vapour barrier. Therefore, the gaps between VIPs have
to be tightened by vapour-barrier foils.
VIP layers within constructions have to be protected against damage, e.g.
drilling, knocking in a nail.
