High Performance Acoustic Floor System
Trim Defender 18 is a high performance soundproofing floor system designed to reduce sound transmission through new build and existing properties.
Trim Defender 18 has a nominal thickness of 18mm and consists of 9mm moisture resistant MDF bonded to 9mm of recycled foam, the base is protected by an anti crumb encapsulating layer.
When installed as part of a complete sound reduction system it enables a timber floor to meet the sound transmission regulations of Document E.
Trim Defender 18 should be laid onto the existing timber floor in a broken bond pattern with all joints glued and perimeters sealed using 19mm x 5mm Perimeter isolation tape.
After installation is complete ensure any remaining gaps are sealed with Duoseal acoustic mastic, see fitting instructions for full details.

Flanking Transmission
The acoustic performance of a floor can be compromised by the passage of sound through walls and ducts, which adjoin or penetrate a floor, known as flanking transmission. To reduce this the acoustic flooring must be isolated from walls and other structural elements. Trim Acoustics Isolation Strip is a flexible polyethylene strip designed to form a seal between the flooring and the wall.
