A flat roof insulation system can do far more than simply keep heat inside the building during the winter months. Our insulation systems help create a comfortable environment all year round, across a wide range of external and internal conditions, by managing the effects of heat, cold, noise and internal moisture.

Keep the building warmer for longer in cold weather:
Low thermal conductivity combined with high vapour permeability delivers excellent thermal performance without the risk of interstitial condensation. Vapour barriers are typically unnecessary. Wood fibre boards help minimise thermal bridging, while the interlocking board design supports effective windtightness, improving overall performance. Reduced heating demand can contribute to lower CO2 emissions and running costs.
Keep the building quieter:
The high mass and fibrous structure of Pavatex wood fibre boards provide strong acoustic performance, helping create calmer internal spaces.
Keep the building cooler in hot weather:
The combination of high density, high specific heat capacity and low thermal conductivity allows our flat roof solutions to slow heat transfer into the building. The result is a more stable internal temperature throughout the day and night, reducing overheating and improving comfort.
Keep the building dry and breathable:
Pavatex wood fibre boards are highly vapour permeable and hygroscopic, allowing them to buffer and safely disperse short-term moisture while protecting vulnerable elements of the building fabric without compromising performance. Moisture within the structure can migrate outward, helping safeguard against elevated moisture levels. This supports the long-term health of the building fabric, an area often overlooked by conventional insulation systems.
This low embodied carbon solution is the first choice for specifiers and homeowners alike. Woodfibre roofs are the simple, yet sensible system for zero carbon homes of the future.
The system is suitable for most external finishing options, including; sedum, metal, timber or similar decking
