General fitting and building application instruction

Vacuum insulation panels need to be treated with great care. When further processing the products va-Q-vip B and va-Q-plus F (incl. GGM & EPS), the following points must be noted:

va-Q-vip B and F are highly efficient thermal insulation materials. Their extraordinary insulation effect is based essentially on the suppression of the thermal conduction of air inside the panels due to evacuation. va-Q-vip B/F received general building material approval under the number Z-23.11-1658. The core itself is non-combustible (fire class A1). The wrapping is ordinarily inflammable according to construction materials class DIN 4102-B2.

  • Vacuum insulation panels (VIPs) should not be mechanically damaged. Sawing, drilling and scratching in particular must be avoided.
  • The underground to which VIPs are applied must be smooth, flat and free of edges and burrs.
  • VIPs should not be exposed to high temperatures, high humidity levels and/or aggressive gases during storage or application. Persistent humidity levels above 60% relative humidity and temperatures above 50 °C in particular should be avoided.
  • Please note that thermal bridges occur to a much greater extent in VIP constructions than in constructions using conventional insulation materials. Since humidity in particular can condense on cold areas of the panel, corresponding vapour barriers must be used in constructions with VIPs. These vapour barriers also prevent condensation of humidity on the panel.
  • During installation and use of VIPs these must not be subjected to any, or if unavoidable, only to minor mechanical stress. Strains on parts of the VIP and persistent vibrations or tension to the cover must be avoided.
  • In constructions with VIPs, please ensure that they are subjected only to even, full-surface pressure loading.
  • VIPs should be protected against tensile and shear forces. This can be achieved by ensuring that the structural strength in a construction using VIPs is provided by other means, and the VIPs carry out only at thermal insulation function.
  • VIPs can be fixated usind adhesives a 2-component polyurethane adhesive or hot-melt. Foaming with polyurethane foams is also possible. In any case, the temperatures occurring during these processes should not exceed 100 °C. A test is advisable, and required, in individual cases.
  • High temperatures and high humidity can degrade the service life of VIPs, even at low temperatures and high humidity. Condensed water on the panel surfaces should be avoided. Already during the panel installation, it is important to make sure that no moisture enters the panel area (for example by rain). Alkaline, aqueous adhesives should not be used for the installation of the panels. Dispersion adhesives and (two-component) PU foam are very well suited for constructions using VIPs.
  • People working with VIPs should be adequately trained in advance. In particular, processing instructions should be explained with regard to the individual application and usage.
  • The insulation construction should be executed in a way that ensures that the ventilation of individual VIPs does not lead to technical problems within the overall system.
  • VIPs must also be adequately protected against damage during the usage phase, e.g. by attaching an outer shell.
  • When installing in floor systems, avoid walking on the unprotected VIPs.
