Hush Seal 20 – Perimeter Seal - 10m

Hush-Seal 20 Perimeter Seal is a high-performance, flexible acoustic sealing strip specifically engineered to prevent sound flanking and enhance the overall acoustic integrity of separating floors and walls. This accessory plays a vital role in ensuring compliance with Building Regulations Part E (Resistance to the Passage of Sound) and achieving superior acoustic performance in both new build and refurbishment projects. Manufactured from a dense, resilient closed-cell polyethylene foam, Hush-Seal 20 provides an effective acoustic break between rigid building elements. It is primarily used around the perimeters of floating floor systems (such as acoustic overlay boards or independent floor joists) and at the edges of acoustic wall linings, where they meet existing structures like joists, walls, or floor slabs. By compressing slightly, it creates an airtight and sound-tight seal, preventing sound energy from bypassing the main acoustic insulation system. Hush-Seal 20 Perimeter Seal is an indispensable element for achieving robust acoustic separation, contributing significantly to improved privacy, reduced noise disturbance, and overall occupant comfort in residential, commercial, and educational environments.
