Flat Roof Insulation Systems

A flat roof insulation system can do far more than keep heat inside the building during winter months. Our insulation systems will create a comfortable environment all-year round, in all types of external and internal conditions, by controlling the effects of external heat, cold, noise and internal moisture generation.

Keep the building warmer for longer in cold weather: Low thermal conductivity and high vapour permeability provide high thermal insulation with no risk of interstitial condensation. Vapour barriers are unnecessary. Wood fibre boards reduce the effect of thermal bridging and the interlocking board design easily achieves good windtightness, so increasing thermal performance. Energy use for heating is significantly reduced leading to lower CO2 emissions and running costs.

Keep the building quieter: The high mass and the fibrous texture of Pavatex wood fibre boards gives excellent acoustic performance to buildings.

Keep the building cooler in hot weather: The unique combination of high density, high specific heat capacity and low thermal conductivity gives our flat Roof solutions the ability to control the flow of heat into the building from the outside. The result is a more consistently cooler temperature all day and night rather than huge peaks and troughs.

Keep the building dry and breathable: Pavatex wood fibre boards are very vapour permeable and hygroscopic. This allows them to disperse accumulating short term moisture and protect vulnerable elements of the building fabric, with no reduction in the performance of the boards themselves. The boards allow moisture from within the structure to pass easily to the outside. This provides a safeguard against high moisture content. This is vital for the long-term health of the building fabric, and is completely overlooked by most conventional insulation systems.

Ventilated Flat Roof 

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

Flat Roof with Exposed Rafters

The build up consists of sustainable insulation over the rafters, airtightness and wind tightness layers, the ceiling rafters are left exposed internally.
