Breathing Membranes

 

Breather felt membranes

Part of The Specialist membrane range, Permo Air is Klober’s most breathable membrane and best-selling roof underlay. The air-open, vapour permeable roof membrane is available with or without self-adhesive tape.

  • Minimises the risk of condensation forming, particularly during the drying out period of a building, such as new-build properties
  • BBA & NHBC approved as needing no additional high level ventilation, making it particularly cost and time effective
  • Available with or without self-adhesive tape, which creates a durable weatherproof seal, to reduce energy loss and provide strong protection against winds

Part of The Everyday membrane range, Permo Light is Klober’s superior day-to-day breathable roof underlay solution. The strong three-layer, vapour-permeable membrane allows the roof structure to breathe and is suitable for most roofing projects.

  • High performing membrane suitable for most roofing projects
  • A durable three-layer breathable membrane
  • BBA approved low resistance membrane

This VP300 vapour permeable felt roof underlay from Glidevale Protect can deliver a secondary line of protection against wind-driven snow and rain while reducing wind uplift loads on the roof covering. It can also be used as a temporary roof covering prior to your tiles or slates being installed.

This medium-weight vapour permeable roof underlay has a greater vapour resistance than required by BS 5250 and is stronger than many other underlays in its class. Suitable for all pitched roofs, especially completely supported applications, this underlay provides a cost-effective solution for when the highest specification of roof underlay, such as VP400 Plus LR, is not needed.
