PhotonAirIcon PhotonAir3D
Unique air-open, insulating breather membrane.

PhotonAir is an air-open reflective insulating breather membrane which combines the thermal performance of multifoil insulation with Klober Permo® air underlay, for use on the cold side of the building in roofs and walls.
  • Upgrades thermal performance without the risk of condensation
  • No Vapour Barrier needed, no counter-battening required
  • Air-open membranes allow more water vapour to pass than air-closed membranes
PhotonFoilIcon PhotonFoil3D
Thin, reflective insulation at a price you want to pay.

PhotonFoil is a thin, reflective composite insulation and an everyday option for loft conversions, extensions and re-roofing projects. An excellent vapour and air leakage barrier with a high density glass wool core and low emissivity outer layers.
  • Core R value with 2 air spaces 2.35 M2K/W
  • 0.18 U-value with 65mm foiled rigid insulation
  • Easy to cut and screws without snagging
