Extra mass for quieter rooms
Hush Cem Panel 28 combines an 18mm tongue-and-groove cement particle board with a 10mm Hush Felt resilient layer bonded to the underside. The added mass boosts airborne sound insulation in lightweight constructions, while the resilient backing helps reduce impact noise from footsteps.
This gives Hush Cem Panel 28 an advantage where standard acoustic flooring mainly tackles impact noise and extra airborne insulation is needed too.
Acoustic performance
Typical performance is 56 dB L’nT,w for impact sound, 61 dB DnT,w for airborne sound and 57 dB DnT,w + Ctr.
Hush Cem Panel 28 is used in floor systems designed to meet Building Regulations Part E in England & Wales, Section 5 in Scotland and Part G in Northern Ireland. It can also be used to form a Robust Details compliant system.
A stable base for your floor finish
The cement particle board provides a very stable surface for a wide range of floor finishes. The board surface is Class 0 fire rated, and thermal conductivity is 0.26 W/m.K.
Installation essentials
- Lay Hush Cem Panel 28 in a broken bond pattern, with staggered board joints.
- Glue every tongue-and-groove joint with cement panel adhesive.
- Isolate the room perimeter with Hush Seal 20.
How many boards do I need?
Divide your room area in m² by 0.72, add about 10% for cuts, then round up to a whole board.
For example, a 20m² room needs 20 ÷ 0.72 x 1.10 = 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.
For example, a 5m × 4m room is 20m² with an 18m perimeter: allow 1 adhesive bottle and 2 lengths of Hush Seal 20. Allow extra for cuts, joints and awkward edges.
-
Estimate one 1L bottle per 20m² for tongue-and-groove joints; round up.
