Applications

This versatile 140mm PIR insulation board is suitable for a multitude of applications across the building envelope. It is widely used for insulating pitched roofs (between and over rafters), flat roofs (below timber joists, balconies, and terraces), and various floor insulation systems including solid concrete slabs, suspended timber joists, and beam and block floors. Furthermore, it excels in wall insulation, including masonry walls, cavity walls (partial or full fill), timber frame, and steel frame systems, as well as internal linings and ceilings.
