50m2 roll of 4mm high quality underlay, made from a 3mm layer of physically cross-linked polyolefin foam and a 1mm layer of high density rubber. Ideally suited to heavy domestic and commercial applications and for use in acoustically sensitive areas, as it combines effective in-room (drum) sound quality improvement and transmitted (impact) sound reduction.

Provides a vapour barrier when used with waterproof jointing tape and laid in accordance with fitting instructions.

Suitable for use beneath surface underfloor heating (ribbon, wire etc.)

(Operating temperature -50ºC to 100ºC)

Always read and follow the guidelines supplied with the underfloor heating system and/or floor to be fitted.

Acoustalay should be used as an insulating/spot levelling layer between the floor to be laid and the sub-floor.
