va-Q-vip B
va-Q-vip B is a vacuum insulation panel for construction applications. va-Q-vip B is covered in a high barrier film and an additional black glass fibre textile for mechanical shock protection. va-Q-vip B with black glass fabric is standardly flammable (construction materials class DIN 4102-B2).va-Q-vip B is approved for general construction purposes in accordance with approval number Z-23.11-1658 of the "Deutsches Institut für Bautechnik (DIBT)". On July 1st 2015 the validity of this approval was extended until June 30th 2020.
va-Q-vip B elements are unique because of their rectangular edges and corners. This is due to the special edge folding technique "va-Q-seam". Individual elements can be joined together almost seamlessly.
