Description

Pavaflex flexible wood fibre insulation is a natural, breathable and flexible insulation made from wood fibres and is treated with inorganic salts to provide fire and pest resistance. It has a good insulation K value of 0.038 W/mK and a density of 55kg/m3. Its hygroscopic nature means it is able to absorb moisture without adversely affecting the quality of the material.

As a natural wood based material, more carbon is locked up in Pavaflex than is released in production making it carbon negative. Its non-toxic nature also ensures it is easy to handle and not unpleasant to work with. It can be easily cut using the Pavaflex insulation knife and a handy tip is to cut the Pavaflex while it is within its packaging. This ensures the batts are held tightly and compressed, making cutting easier.
