Acoustic Strip

Monarfloor® Acoustic Strip system is designed to reduce sound transmission through timber floors in new and refurbishment projects.

Monarfloor Acoustic Strip consists of a layer of LRAC foam bonded to a securing membrane and reinforced with a plywood backing.

When installed as part of a complete sound reduction system it enables a timber floor to meet the sound transmission regulations of Part E (see tables).

Note: an additional layer of 19mm plank plasterboard laid over the Acoustic Strip would be expected to provide an improvement in performance.
