Unique air-open, insulating breather membrane. Click for Product Page
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
