va-Q-vip is a microporous insulation material based on fumed silica powder. va-Q-vip 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 powdered core material ensures the outstanding insulation ability for the entire service life of the product. The typical fields of application are hot water tanks, logistics (cool boxes, etc.) and the automotive sector.

Advantages of va-Q-vip

  • Minor thermal conductivity
  • Drastically reduced insulation thickness
  • Increased useable volume
  • All-purpose VIP with a long service life
