Product Information
Add acoustic mass while keeping floor height down. Hush Cem Panel 18 Cement Particle Acoustic Floor Board is a thin, dense overlay designed to improve airborne sound insulation and work above underfloor heating.
Each 1200 x 600 x 18mm board covers 0.72m². Its cement particle construction has tongue-and-groove edges on all four sides and no bonded felt or rubber layer.

A thinner choice in the Hush Cem range
Hush Cem Panel 18 gives you the high-mass board in an 18mm profile. Compare it with the thicker acoustic-backed Hush Cem Panel 28, 32, 33 and 37 when choosing the layers and floor height your project needs.
Underfloor heating and acoustic performance
Hush specifies Cem Panel 18 over extruded polystyrene UFH systems or roll-out electric heating mats. Thermal resistance is 0.069m² K/W, helping heat pass through the overlay.
Hush’s published UFH floor and acoustic ceiling test returned 56 dB L’nT,w impact, 61 dB DnT,w airborne and 57 dB DnT,w + Ctr. The board adds mass for airborne insulation; the tested arrangement also addresses impact noise. Lower impact and higher airborne figures indicate better insulation in comparable tests.
Installation essentials
- Lay boards with staggered joints in a broken bond pattern.
- Bond all tongue-and-groove joints with cement panel adhesive.
- Isolate the perimeter using Hush Seal 20 or Hush RD Flanking Strip. Use RD Flanking Strip where the Robust Details specification requires it.
How many do I need?
Divide the floor area in m² by 0.72, include a cutting allowance if needed, then round up to whole boards.
For example, 20m² with an optional 10% allowance needs 20 × 1.10 ÷ 0.72 = 30.56, rounded up to 31 boards.
You’ll also need
Plan adhesive from the floor area and perimeter isolation from the room edge measurements. Choose the specified perimeter detail: Hush Seal 20 and Hush RD Flanking Strip are alternatives.
For example, a 5m × 4m room is 20m² with an 18m perimeter: allow 1 adhesive bottle and 2 lengths of Hush Seal 20, or 1 roll of Hush RD Flanking Strip where specified. Allow extra for cuts, joints and awkward edges.
