Insulation through vacuums. High performance thermal insulation for buildings envelopes and windows.

Artikel

What works for thermos flasks can also be used for thermally insulating buildings: insulation by means of a vacuum. For this purpose, panels made of compressed silica powder, which is an extremely porous material, are enclosed in a largely gas- and water vapour-tight envelope made of special high-barrier films or stainless steel and evacuated. The thermal insulation provided by these vacuum insulation panels (VIPs) is five to ten times that achieved by conventional insulation systems. This means that vacuum insulation requires a correspondingly lower thickness of insulation material to achieve the same insulating effect, which is highly beneficial when there are space constraints or high thermal insulation requirements.
