During manufacturing, Kingspan 75mm PIR receives a low emissivity composite foil facing on both surfaces. This reflective layer enhances thermal resistance in unventilated cavities adjacent to the board.
75mm Kingspan Thermapitch TP10 utilises Nilflam® technology, delivering a premium fibre-free rigid thermoset polyisocyanurate (PIR) core. The manufacturing process employs a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP).
When tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 75mm Kingspan PIR insulation typically achieves compressive strength exceeding 140 kPa at 10% compression.
When tested in accordance with BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties), the product typically attains a resistance well above 100 MNs/g.
The longevity of 75mm TP10 depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, the product can deliver long-lasting performance.
75mm Kingspan Insulation TP10 achieves an F Euroclass rating under System 4 AVCP. When installed in pitched roof constructions beneath suitable roof coverings, it satisfies national requirements for external fire exposure.
