A durable plywood surface for your floor
Hush Ply 28 brings together 18mm WBP tongue-and-groove plywood and a 10mm Hushfelt resilient layer factory-bonded to the underside. The strong, durable and water-resistant board is especially useful where your floor finish needs screw fixing, such as engineered wood.
Acoustic performance
Typical acoustic performance is 54 dB L’nT,w for impact sound, 60 dB DnT,w for airborne sound and 54 dB DnT,w + Ctr. Hush Ply 28 helps tackle both footsteps travelling through the floor and airborne noise such as voices and TV.
Hush Ply 28 is used to meet Building Regulations Part E in England & Wales, Section 5 in Scotland and Part G in Northern Ireland. It is Robust Details FFT5 compliant for floor structures EFC-1, EFC-2 and EFS-1.
Overlay or direct-to-joist installation
Lay Hush Ply 28 over concrete or existing timber floors, or directly over joists at up to 450mm centres when used with Hush 10 Joist Strip. It suits new builds, changes of use and refurbishments, bringing the acoustic layers together in a single, time-saving operation.
- Finished floor height over a floor deck: 26mm.
- Finished floor height over timber joists with Hush 10 Joist Strip: 36mm.
Glue all tongue-and-groove joints with Hush Bond and isolate the room perimeter with Hush Seal 20.
Choosing your floor finish
The plywood surface is ideal for finishes that need screw fixing, including engineered wood. Hush Ply 28 can also be tiled over when used with Permalayer and a flexible tile adhesive.
How many boards do I need?
Divide your room area in m² by 1.44, allow about 10% for cuts, then round up to a whole board.
For example, a 20m² room needs 20 ÷ 1.44 x 1.10 = 15.28, rounded up to 16 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.
