Self-adhesive butyl and aluminum mat, 80 mil, designed for soundproofing your vehicle.

The DETOUR LAB vehicle soundproofing material is based on a three-layer composite structure. The outer face consists of a heat-resistant laminated aluminum film. The central layer, made of 2 mm high-density butyl rubber, absorbs vibrations and blocks sound transmission thanks to its low air permeability. The back is covered with a high-adhesion acrylic adhesive — no additional product is required for installation.

Technical specifications

Total thickness: 2 mm.

Surface density: ~2.5 kg/m².

Operating temperature range: –20 °C to +120 °C.

Sheet size: 30 × 40 cm.

Coverage per pack (34 sheets): 4.08 m².

Performance

Beyond reducing rolling noise and body vibrations, the material offers thermal insulation by reflecting engine and floor heat, resistance to moisture and splashes, as well as fire resistance suitable for interior vehicle use.

Installation

Installation is done in four steps: cleaning and degreasing the surface, cutting to the desired shape, removing the protective film, then applying with pressure. A roller tool is recommended to ensure adhesion on curved areas (not included).

Application areas

Doors · cargo space · floor · transmission tunnel · trunk · rear shelf · wheel arches.

The perfect duo with Thinsulate SM600L

The two materials address different issues and naturally complement each other. DETOUR LAB butyl is applied directly to the metal and stops vibrations at the source — rolling rumbles, body resonances, low engine frequencies. The 3M Thinsulate SM600L then takes over on two fronts: acoustic first, by absorbing mid and high frequencies like air noises and whistles, but also thermal. Its microfibers create an insulating barrier that significantly slows heat exchange between the cabin and the outside — an asset both in summer to limit overheating and in winter to retain heat and reduce the load on the heating system. One dampens the structure, the other insulates from sound and cold. Together, they cover the entire acoustic and thermal spectrum where each alone reaches its limits.
