The DuPont Air Reflective Membrane

The DuPont Air Guard Reflective membrane  is a 100% air tight & vapour control layer.

The membrane is made with a metallised surface which has a very low emissivity.

This combined with a non-ventilated airspace significantly boosts thermal insulation in a building.

It can be installed in roofs,within the walls as you can see below .It can also be used  below ceilings.

Using the membrane and ensuring the joints are sealed properly using the tyvek airtight tape will allow for the following:

  • Thermal comfort – it provides protection against heat loss by radiation and convection.
  • An efficient moisture management – it provides effective control against interstitial condensation both by diffusion and by convection.

  6. CE-conformity for plastic & rubber vapour control layer
  7. Reflects ca. 95% of radiant heat
  8. Impressive mechanical strength
