Multi-foil insulation for external re-roofs and new builds.
Suitable for difficult to insulate pitched roofs as it can be installed without a vapour barrier and can also be installed without the need to counter batten so there is no change in roof height.
PhotonAir is a 2 in 1 breathable multifoil insulation combining the thermal performance of multi foil insulation with Klober Permo® air underlay. Installed in the same way as a standard breathable roofing felt, PhotonAir is water tight and upgrades the thermal value of your roof whilst removing the risk of condensation.
The insulation is constructed with high density glasswool at its core, encapsulated between a perforated reflective lower layer and Klober Permo® air.
PhotonAir is a true low resistance (LR ) underlay:
The product has been independently tested and certified to the latest European Standards by accredited European test houses and has achieved LABC (Local Authority Building Control) Registered Details.
