IXPE Underlays

Irradiated cross-linked polyethylene (IXPE) foam underlays are a high-performance premium solution that offers a cleaner alternative to traditional foam materials. They provide superior moisture resistance, long-term compression recovery, and acoustic performance, while also being more environmentally responsible in both manufacturing and end-use.

Material Overview — IXPE

Irradiated cross-linked polyethylene (IXPE) foam is produced by irradiating expanded polyethylene with an electron beam, forming a cross-linked cellular structure. This process produces a foam with a closed-cell architecture that is inherently resistant to moisture ingress, compression set, and mould growth.

The IXPE range from OPUS is available in 1 mm, 2 mm and 3 mm thicknesses, with PE film, aluminium foil, aluminium film, and gold film surface coatings. Factory-perforated variants are available for installations requiring enhanced breathability or improved heat transfer performance, such as flooring installations over underfloor heating systems.

  • 33–133 kg/m³ density
  • Exceptional noise reduction
  • Built-in moisture barrier
  • Anti-crush performance
  • Mold & mildew resistant
  • Zero VOCs
  • Excellent heat transfer
