Ravatherm XPS Insulation Board

Ravatherm XPS insulation boards are high-performance extruded polystyrene (XPS) solutions designed for demanding applications where moisture resistance and compressive strength are critical. With a closed-cell structure, Ravatherm boards deliver exceptional thermal insulation and long-term durability, even in below-ground and inverted roof environments.

Ideal for basements, floor slabs, green roofs, and inverted flat roofs, Ravatherm boards resist water absorption and withstand heavy loads—making them perfect for both residential and commercial builds. Their low thermal conductivity and strong mechanical properties help reduce thermal bridging and improve overall energy efficiency.

At Insulation UK, we stock a wide range of Ravatherm XPS insulation boards, available in multiple thicknesses and grades to suit your project’s technical requirements. Whether you're insulating under a concrete slab or waterproofing a roof, Ravatherm provides a robust, long-lasting solution.
