Warm Roof - Getting Started – An introduction to our Warm Roof System?

Tŷ-Mawr’s Warm Roof System has a superb thermal and acoustic performance and its vapour permeability also helps to regulate humidity within the building contributing to a more comfortable and healthier living environment.

This system is an ideal solution for refurbishment of existing roofs but can also be used as a sustainable warm roof design in ecological new builds.

The Tŷ-Mawr’s system offers a choice of high quality, ecological and sustainable insulation materials. The system comprises: water resistant, interlocking woodfibre board over rafters and natural fibre insulation between rafters.

Further woodfibre boards can be fitted below rafters before plastering if required or, alternatively, CeWood Wood Wool board can be installed as the lime plaster carrier. For roofs with bats, the use of breathable roofing membranes is not allowed.
