Hush - Ply 28
Floating Flooring

Hush-Ply 28 has been designed as an impact reducing floor panel that can be used as a structural or an overlay board. Offering an alternative to the standard chipboard finish, Hush-Ply 28 is especially suitable for areas requiring extra moisture protection, such as kitchens and bathrooms and offers an excellent surface for application of the final flooring finish, whether using ceramic tiles or wooden flooring.


  • A strong and durable waterproof plywood surfaced panel for use in many situations requiring impact sound insulation between separating floors.
  • Ideal for flooring finishes which require screw fixings such as engineered hardwood flooring.
  • Used within refurbishment and new build projects to create a floating floor over concrete and timber floors or directly over timber joists*.
  • Compatible with a range of Hush-Systems, designed to exceed the current >Building Regulation requirements of Part E (England and Wales), Part H (Scotland) and Part G(Northern Ireland).
  • Robust Details FFT5 compliant for floor structures EFC-1, EFC-2 and EFS-1.
  • Comprises 18mm WBP TG4 plywood panels and a 10mm acoustic resilient layer of  Hushfelt™ factory bonded to the underside.
  • Easy to install in a single time saving operation.

*In conjunction with Hush-10 Joist Strips

Special Sizes

Hush-Ply 28 can be manufactured to bespoke sizes up to a maximum of 1.8m x 3.6m, where one piece flooring sections are required, such as hotel bathrooms.


1. Lay the Hush-Ply 28 Floating Flooring in a conventional broken bond pattern. When laying directly over joists, Hush-10 Joist Strips are simply stapled onto the joist tops prior to application.

2. Glue all teegee joints using Hush-Bond Panel Adhesive.

3. Leave a 10-15mm expansion gap around all perimeters and press in Hush-Seal 20 Perimeter Seal ensuring that the floor floats freely of the walls maintaining acoustic isolation or perimeter detail as per Robust Detail instructions using Hush-RD Flanking Strip.

At door thresholds, access hatches or in the absence of a teegee joint Hush-Grommet Fixing Isolators can be used sparingly to eliminate ‘lipping’. No other fixings should be used when fitting the floating floor as any restrictions can adversely affect performance. Skirting should be fitted two or three millimeters clear of the floor surface. (PCT only).
