A modern roof insulation system must do more than just protect building occupants from cold. It must create a comfortable and healthy environment in all possible combinations of external and internal conditions and control 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 wind tightness, 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 woodfibre 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 Unity Lime’s Pitched Roof solutions the effect of thermal mass that would normally be associated with green roofs. Compared to conventional sarking material the risk of condensation behind it during cold nights is minimized as the boards will store the day’s heat.
Keep the building dry and breathable:
PAVATEX woodfibre 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.
