Comfort Mats EXTREME 3.5mm – Double-Layer Vibration Deadening Mat
The Comfort Mat EXTREME 3.5mm is the ultimate first-layer vibration deadening solution engineered for enthusiasts and SPL competition builders alike. Featuring a unique double-lamination of bitumen and mastic composition reinforced with two layers of aluminum foil, this mat delivers exceptional rigidity, a high mechanical loss factor, and outstanding adhesion — even in the most demanding, high-vibration environments.
Key Features
- Double-Layer Construction: Two functional layers of bitumen/mastic and dual 100-micron aluminum foil combine for superior stiffness and vibration absorption.
- High Mechanical Loss Factor: A rating of 0.63 ensures maximum energy dissipation, drastically reducing unwanted resonance and road noise.
- Modified Elastomer Mastic: Provides exceptional adhesion (11 N/cm), wide temperature tolerance, and strong resistance to moisture and environmental exposure.
- 100% Waterproof: Fully sealed construction protects against moisture ingress in all installation areas.
- Versatile Application: Designed as the ideal first layer for floors, firewalls, wheel arches, doors, roofs, and trunks — including SPL competition vehicles.
- Large Sheet Size: Each 480 x 700mm sheet provides generous coverage per piece, reducing installation time and material waste.
