Description

Isolair by Pavatex is a multipurpose homogeneous wood fibre insulation board used for a wide range of applications. A sustainable and natural internal and external insulation product.

Isolair provides a tried and tested wood fibre system in the UK that are effective in reducing the U value (thermal transmittance), in improving acoustic sound protection and summer heat protection (decrement delay).
Therefore buildings insulated with Isolair are much less prone to overheating during periods of sustained hot weather. Wood fibre insulation guarantees an active breathing housing and the boards will not present a toxic hazard.

Suitable for use with Passive House and Code 6 new buildings.

Can be left exposed for up to 90 days.
