Fixings should be positioned not less than 10mm from board edges and not less than 50mm from board corners

140mm Kingspan TW55 ThermaWall PIR Insulation Board 2.4m x 1.2m Express Delivery providing a robust foundation for140mm Kingspan Thermawall TW55 is one of the two thickest boards in the range, a fibre free rigid thermoset polyisocyanurate (PIR) insulation core faced on both sides with a low emissivity composite foil. Boards measure 2400mm x 1200mm and cover 2. 88m, with a declared thermal resistance of 6. 35 mK W at a thermal conductivity of 0. 022 W mK. That figure puts a single 140mm layer well past what most standard wall build ups require, which is why it
