Pavaflex flexible wood fibre insulation is a natural, breathable and flexible insulation made from wood fibres.
Pavaflex is treated with inorganic salts which provides fire and pest resistance. It has a good insulation K value of 0.038 W/mK and a density of 55 kg/m³. In addition, 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 – therefore making it carbon negative.
It’s non-toxic nature also ensures it is easy to handle and not unpleasant to work with. Use the Pavaflex Insulation Knife for easy cutting. A handy tip is to cut while it is within the packaging – this ensures the batts are held tightly and compressed, making cutting easier.
