Installation Guidance – Vacuum Insulated Panels

Installation Guidance – Vacuum Insulated Panels 

Va-Q-tec vacuum insulation panels are highly efficient thermal insulation materials. The extremely good insulation performance is based essentially on the suppression of the thermal conduction of the air inside the panels due to evacuation. The va-Q-vip B/F have general building material approval under the number Z-23.11-1658 in Germany. The core itself is seemed non-combustible (European Fire class A1). The wrapping is classified as inflammable according to construction materials class DIN 4102-B2.

Vacuum insulation panels in general need to be treated carefully. In the further processing and installation of the products, the following points must be noted in particular:

 

  • The vacuum insulation panels (VIPs) must not be mechanically damaged. Sawing, cutting, drilling and scratching in particular must be avoided.
  • The surface to which the VIPs are applied must be smooth, flat and free of edges and burrs.
  • The VIPs must 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 at cold spot, corresponding vapour barriers must be used in constructions with VIPs. Vapour barriers can also minimise the risk of condensation on the panels.
  • During installation and use of VIPs, they must not be subjected to any, or if unavoidable only minor mechanical stresses. Point loads and persistent vibration or tension to the wrapping must be avoided.
  • In constructions with VIPs, care must be taken to ensure that they are subjected only to even, full-surface pressure loading.
  • The VIPs must be protected against tensile and shear forces. This can be achieved for example, by ensuring that the structural strength in a construction using VIPs is provided by other measures, and the VIPs are only required to function as thermal insulation.
  • Adhesive fixing of the VIPs can be carried out using 2-components polyurethane adhesive or hot-melt. Foaming with polyurethane foams is also possible. In all cases, care must be taken to ensure that the temperatures occurring during these processes do 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  as can low temperatures and high humidity. Condensed water in particular should be avoided to the panel surfaces. During the installation of the panels, make sure that no moisture is present, for example from rain. Alkaline, aqueous adhesives may not be used for the installation of the panels. Dispersion adhesives and (two-component) PU foam are very well suited for the adhesion of VIPs.
  • It must be ensured that persons working with VIPs are adequately trained in advance. Fitting and working instructions in particular should be explained with regard to the individual application.
  • VIPs should be placed in such a way that the integrity of the overall application is not put at any risk.
  • The VIPs must also be adequately protected against damage during the usage phase, e.g. by fitting of an outer shell.
  • When installing in floor systems, avoid walking on unprotected VIPs.
