TITAN BARRIER Underlay | Premium Acoustic & Heat Insulation Sheet for Floors – Soundproofing & Thermal Defence Solution

Titan BARRIER 4mm Waterproof Acoustic Foam Underlay 375x500mm 10 Pack

The Titan BARRIER is a 4mm waterproof acoustic foam underlay supplied as ten peel-and-stick sheets measuring 375 x 500mm each for a total coverage of 1.87sqm. Designed primarily for floor installations, it absorbs sound waves and provides noise and heat isolation from below, making it suited to hot environments and vehicles with engines located beneath the floor. It can also be installed in doors to enhance acoustic performance, ideally over Titan SHIELD for best results.

Product overview

The BARRIER uses a 4mm acoustic foam construction that is waterproof, fire resistant, and peel-and-stick backed for straightforward installation on floors and door panels. The foam layer absorbs airborne noise and vibration energy coming through the floor, reducing road noise, engine noise, and heat transfer in vehicle applications. In home and studio environments, it suits floor underlays where acoustic dampening and thermal insulation between rooms or from external sources is required.

For maximum performance in vehicle floor installations, Titan recommends installing BARRIER over SHIELD butyl damping sheets. The ten-piece pack provides 1.87sqm of total coverage, suited to targeted floor treatment across footwell areas and transmission tunnel panels in most vehicle installations.
