Product description

Acoustic flooring underlay with vapour barrier and adhesive strips

Alfa PE Impact Sound Insulation ALU SK is an acoustic underlay mat for floating prefinished wood floors, cork and laminate flooring etc in rooms with normal traffic. Not suitable for glue-down parquet floors, adhered tiles or adhered natural stone floors.

The impact sound insulation is coated with an aluminium vapour barrier. Along one side, a strip with only vapour barrier and no insulation is thinner and allows you to overlap the underlay without creating bulky lines. A self-adhesive film is attached to this strip so that the overlap can be bonded safely and easily.

In order to install the acoustic underlay matting, unroll it on the subfloor with the aluminium covered side facing upwards. Place the mats next to each other, without a gap in the insulation. Let the (vapour-barrier-only) overlap strip overlap. Remove the protective paper from the adhesive film and bond the overlap to the next mat.
