50mm Insulation Boards

Shop 50mm insulation boards at trade prices: 50mm PIR from Kingspan, Celotex (now Sopratherm) and Recticel, 50mm Kingspan GreenGuard GG300 XPS, and 50mm Kingspan Kooltherm phenolic boards for floors, walls, roofs and cavities.

Use 50mm PIR for floors, walls, pitched roofs, partial-fill cavities and flat roofs; XPS where you need a moisture-resistant board under a slab or below ground; and Kooltherm where the build-up is tight. Compare a 50mm build-up with the PIR U-value calculator and the insulation calculator, or read what thickness of PIR you need and PIR vs EPS vs XPS floor insulation.
