STEICO Internal (wet) wood fibre insulation boards offer a high-performance solution for internal insulation of masonry and timber frame structures. Certified by the German Institute for Building Biology Rosenheim, these boards support natural moisture regulation and protect building integrity through their diffusion-open and sorptive properties. Compatible with lime and clay plasters, they contribute to a healthy indoor climate while maintaining building physics safety. Ethically sourced from PEFC-certified responsible forestry, STEICO Internal (wet) ensures sustainability alongside effective insulation.

What does "wet" mean? 
In the wet process, the soaked fibres are formed into panels. Then the panels are calibrated in thickness and dried as whole pieces. The clever bit: in the wet process, the wood's own natural lignin binds the panels. This means that no external adhesives are required, making wet-process insulation boards very eco-friendly and beneficial for your living environment.
