Vapour permeability

Hygrothermal Performance of PAVATEX Insulation Systems

To maintain effective humidity control between interior and exterior environments, building envelopes must be constructed with vapour-permeable materials. PAVATEX wood fibre insulation panels are specifically engineered to meet these requirements. As high-quality, vapour-permeable insulation products with hygroscopic properties, they help regulate moisture levels within the building envelope, reducing the risk of structural damage while contributing to a stable and healthy indoor climate.

Vapour Permeability Through Natural Fibre Structure

The vapour-permeability of PAVATEX insulation products is a result of the naturally porous structure of the wood fibres from which they are made.

This hygroscopic characteristic enables the insulation to buffer indoor humidity and safely transport excess moisture from building components to the exterior. The result is a durable envelope system that supports long-term protection against moisture accumulation, condensation, and mould formation.
