Shop 100mm insulation boards at trade prices: 100mm PIR from Kingspan, Celotex (now Sopratherm) and Recticel, 100mm Kingspan GreenGuard GG300 XPS, and 100mm Kingspan Kooltherm phenolic boards for floors, roofs, cavities, soffits and framing.

Use XPS where you need a moisture-resistant board under a slab or below ground, and Kooltherm where you want a slimmer phenolic build-up. Check a 100mm build-up with the PIR U-value calculator, the insulation calculator, the U-value of 100mm PIR and what thickness of PIR you need.
