25mm Kingspan TP10 ThermaPitch PIR Insulation Board 2.4m x 1.2m

25mm Kingspan Thermapitch® TP10 is a thin roof board for over or under-rafter top-ups and shallow build-ups, including dwarf walls in loft rooms. The rigid polyisocyanurate (PIR) core carries a 0.022 W/mK thermal conductivity and gives 1.10 m²K/W of thermal resistance, with low emissivity foil on both faces. It earns its place where a modest thermal layer is needed on tiled or slated pitched roofs without a deep build-up. A slim option for topping up or fine-tuning a roof's insulation.
