Construction Refurbishment Innovative Thermal Insulation

Vactherm VIP is an evacuated insulation panel with very low thermal conductivity. The core of the panel consists of a amorphous silicon dioxide powder and a inorganic opacifier, coated with a polyester fleece as dust shield and is sealed under vacuum into a metallized high barrier foil. The high barrier foil is covered on the exterior with a black protection fleece

The vacuum insulated panel should be protected from high temperature and humidity, because these may decrease the lifetime of VIPs. Even at low temperature constant
high humidity has to be avoided on the panel surface. Use no alkaline, aqueous building adhesives since these drain badly and endanger the seal seams.
