Description
SELITeco 5 mm acoustic underlay
SELITeco is a green XPS underlay for a compatible parquet, laminate or floorboard construction. The leaflet lists a thickness of 5 mm and dimensions of 0.8 × 7.5 m, covering 6 m². It is supplied as a folding underlay. Please note: the manufacturer states that this version is unsuitable for underfloor heating. Choose an approved alternative for a heated floor.
Sound ratings and apartment requirements
The manufacturer lists up to 20 dB ΔLw. This is a particular measure of impact sound, not a guarantee that every sound in your home will decrease by the stated figure. ΔLlin and ΔLw are different quantities. For owners’ association or landlord requirements, have the test report and specified combination of structural floor, underlay and flooring assessed. A product name alone does not establish approval for your apartment.
Check the substrate and installation
The manufacturer lists local conformability up to 4 mm. This does not replace checks on flatness, moisture and strength. Follow the leaflet for layers, joints and any required moisture protection, together with the flooring manufacturer’s instructions. Allow for cutting waste when calculating quantities. We help private and business end users, installers and wholesalers choose based on the substrate, flooring and required acoustic documentation. Confirm the sales unit and terms before ordering.
