10m2 roll of 2mm high quality, physically cross-linked polyolefin foam underlay designed for extra heavy commercial applications with typical installations including snooker rooms, public buildings, shops, offices and acoustically sensitive areas.

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

Suitable for use with sub-floor embedded, and surface (ribbon, wire etc.) underfloor heating.

(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.
