The 150mm CavityTherm CT/PIR wall insulation board is a sophisticated composite panel incorporating a high-performance PIR core with an exceptional thermal conductivity of 0.021W/mK. These boards feature gas-tight facings, with one side bonded to a profiled HIPS skin during manufacturing to establish a reliable drainage plane. The specially engineered profiled facing of 150mm CavityTherm effectively directs any moisture that may penetrate the external wall downwards along the protective facing, redirecting it to the outer leaf. This construction delivers enhanced resistance against wind-driven rain.
Additionally, the 150mm Unilin Full Fill Insulation Board incorporates precisely engineered rebated edge details on all four sides, creating a secure interlocking system during installation. This engineered interlock design ensures the insulation layer maintains complete continuity, delivering exceptional thermal bridging performance.
When installed in a conventional 100-150mm cavity using standard construction methods and materials, 150mm CavityTherm achieves impressive U-values as low as 0.12W/m2K. This represents a practical and economical approach to meeting low-energy building standards, whilst preserving the aesthetic appeal of traditional properties.
150mm Unilin CT/PIR features a specially engineered profiled facing that effectively manages any moisture potentially infiltrating the external wall insulation by directing it downwards along the protective surface. This design further channels moisture back to the outer leaf, providing superior protection against the increasingly common occurrence of wind-driven rain associated with climate change.
