Warmshell Woodfibre Boards

Warmshell Woodfibre boards are the intelligent insulation option which can buffer and store heat and moisture, keeping you warm and dry in winter and stopping overheating in summer.  Warmshell wood fibre won’t trap moisture because they are highly breathable and exploit woods incredible ability to wick and harmlessly move water. Made with waste sawdust from sustainable FSC accredited forests, they are the sustainable, low carbon option for internal and external wall insulation. And unlike some insulations, our boards are totally free from formaldehyde and other biocides.

Compared to lightweight synthetic insulations, the density of Warmshell woodfibre allows phase-shift  to reduce summer overheating  as well as giving excellent sound deadening acoustic properties.  Warmshell doesn’t just save heat, it creates a comfortable, healthy indoor climate.

The boards can be used as part of our wall insulation system with Internal Plasters, or External Renders, which is availble with detailed guidance, system warranties and installation information.
