Natural wall insulation boards feature the benefit of being easy to install due to the consistently uniform board dimensions. Tongue and groove products such as Gutex Multiplex Top and Ultratherm provide a tight fit, minimising the risk of holes or gaps where heat can escape, and draughts can enter.

With options for use both internally and externally, our range of wall insulation boards features woodfibre external wall insulation products that are waterproof and raintight, as well as natural internal insulation products that prevent mould and control moisture.

Our wall insulation boards are all made from natural materials with proven insulating properties, including woodfibre and calcium silicate. The calcium silicate means that products containing it  are capillary active and vapour open. This means they are able to regulate moisture levels and protect the building from high humidity which can lead to condensation and mould formation.

All the wall insulation products in the Gutex range are biologically safe, manufactured using a carbon negative production process and natureplus® certified, meaning that using them in your construction project is conducive to a healthier building process and a more pleasant building to live and work in.
