va-Q-vip
va-Q-vip is an evacuated micro porous thermal insulating panel with excellent insulating properties. The core material of va-Q-vip is a pressed powder made of silicic acid which is non-combustible. It is vacuum-sealed into a high gas barrier film. Due to the special "edge folding technique va-Q-seam", va-Q-vips have smooth edges. Therefore, individual va-Q-vips can be fitted together tightly, making an almost seamless assembly possible. In general, va-Q-vips are produced in a rectangular shape, but other shapes (such as triangles, trapeziums, cornet cut and oval cut etc.) are available upon request.
