PREMIUM PIR INSULATION

PREMIUM PERFORMANCE PIR

Premium performance PIR insulation is an innovative and improved performance polyisocyanurate solution offering enhanced thermal conductivity of 0.021 W/mK as well as Class O fire performance throughout the entire insulation product. This allows contractors, architects and specifiers to use premium performance PIR in externally cladded walls and for the first time in high-rise constructions above 18m. It has the strength and thermal properties required to reach the high performance U-Values asked for in the Building Regulations. The robust foil facings on both sides of the board incorporate an integral vapour barrier, which helps to reduce the risk of condensation. The typical length and width of a PIR board is 2400mm by 1200mm. Each sheet is 8' x 4' and covers 2.88m2. PIR insulation boards are available in a range of thicknesses such as 12mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 90mm, 100mm, 110mm, 120mm, 125mm, 130mm, 140mm, 150mm, 165mm, 180mm and 200mm. The most commonly used thicknesses are 12mm, 15mm, 20mm, 25mm, 50mm and 100mm.
