Klober Permo Extreme - 25m x 1.5m

SKU
FR080934

Permo air is the most breathable air open low resistance underlay on the market. It is the ideal solution where there is a high risk of condensation forming in the roof space.

Air permeable breather membranes allow both air and water vapour to pass through the membrane meaning additional ventilation may not be required to ventilate a roof and can also reduce the build-up of condensation within the roof structure.

Features

• Air open & vapour permeable.
• Over 13% more breathable than any other ‘air open’ underlay on the market.
• Lowest vapour resistance of all breathable membranes.
• Being both air open & vapour permeable further minimises the risk of condensation forming, particularly during the drying out period of a building.
• No ventilation required.
• Hydrophobically treated.
• Type LR underlay.
• Strong 3 layer material.
• 15 year guarantee.
• Recyclable.
• UV stable for 4 months.
