va-Q-vip B
va-Q-vip B is a microporous insulation material based on fumed silica, with an additional coverage of a black glass fibre textile for higher mechanical protection. The vacuum insulation panel is approved for general construction purposes in accordance with approval number Z-23.11-1658 of the "Deutsches Institut für Bautechnik (DIBT)". va-Q-vip B elements are unique because of their rectangular edges and corners (va-Q-seam) whereas individual elements can be joined together almost seamlessly. In general rectangular panels are produced but various shapes (trapeze, triangle, corner section) are possible on request. The va-Q-vip B can be used in buildings according to the application areas DAD, DAA, DZ, DI, DEO, WAB, WH and WI according to DIN 4108-10, table 1 (floors, flat roofs, ceilings, top floor ceilings, exterior insulation behind panelling, walls, insulation in wood frame construction).
