Product data sheetva-Q-vip
Characteristics | |
va-Q-vip is an evacuated micro porous thermal insulating panel with excellent insulating properties. The core material of va-Q-vip is fumed Silica board and noncombustible. It is sealed into a high gas barrier film under vacuum. Due to the special "Edge fold technique va-Q-seam", va-Q-vip has a smooth and rectangular edge. Therefore individual va-Q-vips can be tightly fitted together, making an almost gapless assembly possible. In general va-Q-vip is produced rectangular shape and other shapes such as triangle, trapezium, cornet cut and oval cut etc. are available on request. |  |
Application | |
va-Q-vip is specially developed for insulation applications where not much space is available but a high thermal resistance is necessary. va-Q-vip is a successful insulation element in the following areas:
For the building application va-Q-vip B (official approval in Germany) can also be used. |  |
Advantage
- Drastically reduced heat fluxes
- Drastically reduced insulation thickness
- Increased usable volume
- All purpose VIP with a long service life
