Benefits of 120mm PIR insulation

Water resistance — Although not waterproof, PIR insulation boards have a low rate of water absorption, providing the material with some protection against moisture damage.
Outstanding thermal qualities — Thanks to their superior thermal resistance, 120mm PIR insulation sheets do not readily transfer heat. This minimises heat loss and enhances energy efficiency.
Fire resistance — PIR insulation does not produce a large flame spread, with many panels having a Euroclass E rating.
Low toxicity — PIR boards are produced using less energy and fewer toxic materials than some comparable boards.
