100m2 roll of 3mm self-adhesive, high quality, cross-linked polyolefin foam underlay with 125mu PE film vapour barrier to EN 13984. The PE film extends beyond the underlay to form a 200mm overlap, featuring an easy-lift adhesive strip to create a complete seal. This eliminates the need for a separate vapour barrier.

Ideally suited to domestic and commercial installations of solid wood floors onto a concrete sub-floor. Typical installations including living rooms, kitchens and hallways.

The self-adhesive backing (protected by a release liner prior to installation) enables flooring to be bonded directly to the underlay significantly reducing installation time, while Acoustalay provides for perfect spot levelling.

Suitable for use with sub-floor embedded 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.
