Arbiton SECURA EXTRA AQUASTOP SMART 3 mm 3-in-1 XPS underlay for floating floors is designed for laminate, timber and vinyl flooring on an HDF subfloor. The underlay is made from high-quality extruded polystyrene (XPS+PET), which ensures an excellent combination of insulation and strength.
With a total thickness of 3 mm, it provides excellent support for floor coverings and ensures optimum insulation. The underlay is not suitable for underfloor heating. The RWS impact noise reduction is 12 per cent, whilst the IS impact noise reduction is up to 21 dB (in the room below), making this underlay an ideal solution for minimising noise.
With an integrated vapour barrier and protection against substrate moisture, it provides excellent protection against damp. It is installed with the silver side facing upwards and is grey in colour with a silver foil. The underlay is packed in a folded/accordion-style format and is also suitable for rooms with medium traffic levels. Supplied in packs measuring 1.18 x 5.1 m.
