Rockfloor Acoustic & Thermal Slab 30mm - 1200mm x 1000
Rockfloor Acoustic & Thermal Slab 30mm is a high-density tissue-faced stone wool slab designed for acoustic and thermal floor insulation. It is used to help reduce impact sound, improve floor insulation and support robust floating floor build-ups in domestic and commercial projects.
The dense fibre structure helps absorb vibration and impact-based sound, making it suitable for floor soundproofing applications where noise transfer through the structure needs to be reduced. It can be used below flooring grade chipboard in dry systems or below suitable screed in wet floor constructions.
At 30mm thick, this slab provides a stronger acoustic and thermal layer than the 25mm version while still keeping the overall floor build-up relatively slim.

Installation Notes
Install the slabs on a clean, level and structurally sound subfloor. Slabs should be laid tightly together with staggered joints to reduce weak points in the build-up. A suitable perimeter isolation strip should be used around the edges of the room to help reduce flanking transmission. Where installed over ground floors or damp substrates, a suitable damp proof membrane may be required.
Final acoustic performance depends on the full floor system, including the slab, deck layer, screed or chipboard, perimeter isolation, sealing and the existing structure.
