Hush - Panel 28
Floating Floor

Hush-Panel 28 has been developed as a sound reducing floor panel that can be used as a structural or an overlay floor board. When used as an overlay board the Hushfelt™resilient layer can be applied to help resolve any instance of undulating in the surface of the boards.

Excellent results are achieved in both refurbishment and new build projects when using Hush-Panel 28 as part of a sound insulation system for separating floors.



  • A adaptable and efficient acoustic panel for use in many situations requiring impact sound proofing and insulation between separating floors.
  • Used extensively within refurbishment and new build projects as a floating floor over concrete and timber 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 High Density P5 Moisture Resistant TG4 chipboard panels and a 10mm acoustic resilient layer of Hushfelt™ factory bonded to the underside.
  • Easy to install in a single time saving operation
  • A Peel Clean version is now available to allow for spotless handovers.

1. Lay the Hush-Panel 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 orperimeter 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 a minimum of three millimeters clear of the floor surface. (PCT only).
