Wallint Solar  


Wallint® solar is Klober's new reflective air barrier and vapour control layer. With a vapour resistance of over 500 MNs/g, it far exceeds the requirements set out in BS9250 (Code of Practice for design of the airtightness of ceilings in pitched roofs). Its reflective surface reduces heat loss through the roof. Moreover, when combined with other products in Klober's airtightness range, it will help to minimise energy loss.

  • Special features Vapour resistance of 250 MNsg. This low vapour resistance quality also allows damp timber to rapidly dry out. Reflective surface.
  • Suitability/use Suitable for inner face of walls (including timber frame), cold and warm roof applications. Also suitable for ceilings and walls of rooms in the roof, and on ceilings below non-habitable lofts.
