warmshell woodfibre boards

Warmshell woodfibre boards are the sustainable, breathable, rigid insulation slabs suitable for direct plastering and rendering. Ideal for retrofit and new build, Warmshell boards can be fitted inside or out, and used with render, plaster or cladding or under roof tiles.

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 boards 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. Compared to lightweight synthetic insulations, the density of Warmshell woodfibre allows phaseshift 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. And unlike some insulations, our boards are totally free from formaldehyde and other chemical biocides.

A range of compatible renders and plasters are available with the boards as part of the system, for assistance choosing the best products for your project, give us a call on 01469531227 or 07743362408.
