The Hush-Felt 25 Joist strips are a cost-effective alternative to composite floating flooring, providing excellent performance. They are designed for use in the construction of floating floors over timber joists in both new build and refurbishment projects. These strips consist of hardboard slats that provide a firm and smooth surface to support chipboard, OSB, or plywood T&G flooring boards. Hush-Felt 25 is also an integral part of a sound insulation system between separating floors.

These strips are designed to provide impact sound insulation between separating floors. They are commonly used in refurbishment and new build projects as part of floating floors over timber joists. They are compatible with various Hush-Systems that exceed the current Building Regulation requirements of Part E (England and Wales), Part H (Scotland), and Part G (Northern Ireland). Each strip consists of a double layer of 10mm Hushfelt™ resilient layer factory stapled to hardboard slats.

Installation

  1. Lay the strips end to end with the hardboard pads facing upwards. Staple through the Hush-Felt into the tops of the joists using 16mm staples. Leave space for a perimeter noggin at the end of the joist runs, onto which a length of Hush-Felt 25 should be installed.
  2. When planning the floor layout, leave a 10-15mm expansion gap around all perimeters. Apply a snake of Hush-Bond Panel Adhesive onto each of the hardboard pads and lay the flooring boards on top in a broken bond pattern. At the same time, glue the flooring boards together at all tongue and groove joints.
  3. Press Hush-Seal 20 Perimeter Seal into the perimeter expansion gap to ensure that the floor floats freely from the walls, maintaining acoustic isolation.

Do not use any other fixings when installing the floating floor, as they can negatively impact performance. Skirting should be installed with a minimum clearance of two or three millimeters from the floor surface (PCT only).
