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).

Advantages of va-Q-vip B

  • Particularly suitable for areas with high resistance to mechanical stress
  • Additional surface protection through fiberglass fabric
  • Enhanced usable room area due to thinner insulation material
  • Smooth edges and no foil overlaps due to patented va-Q-seam technology
  • Approved for general construction purposes according to Z-23.11-1658
  • Long lifetime due to optimized panel design
  • 100 % quality control with the patented gas pressure measurement system (va-Q-check®)
  • Sustainable product (recyclable core material)
