Car soundproofing that reduces road, engine and transmission noise for a calmer cabin. Quieter journeys and clearer in-car audio make commuting and long drives less fatiguing. Is the Dodo Mat DEADN Hex Sound Deadening Mat the right fit for your car and installation needs?
⚡ At a Glance
- • Noise Reduction: Significant reduction in road, engine and transmission noise using a butyl core and aluminium facing
- • Best for: DIY installers and technicians fitting targeted soundproofing to cars and vans
- • Not ideal for: Users who require coverage for large-scale workshop projects beyond a 20 sq.ft pack
High-grade synthetic butyl core bonded to hex-embossed aluminium forms a 1.8mm mat that dampens panel vibration. Twenty 375 x 250mm sheets cover 20 sq.ft (1.8 sq.m) with a strong adhesive backing for straightforward application.
Reduced Rattles and Vibration – thanks to synthetic butyl core
The synthetic butyl chemistry absorbs and dissipates vibrational energy from metal panels without bulky layers. The 1.8mm thickness balances damping performance with manageable weight.
Effective elimination of door and panel buzz improves perceived cabin quality and makes music and conversation clearer. Ideal for addressing specific rattles without heavy sound-deadening builds.
Easy Fit for DIY Installation – with soft, flexible sheets and strong adhesive
Sheets measure 375 x 250mm and are very soft and flexible, allowing them to conform to curves and recesses. A strong adhesive backing secures sheets directly to metal surfaces for a rapid fit.
Simple to cut and place by hand, making precise application to doors, floors and small panels straightforward. Helpful for enthusiasts and mobile installers working without specialist tools.
Controls Condensation and Surface Noise – with hex-embossed aluminium facing
The aluminium facing adds stiffness to the butyl layer while the hex embossing improves contact across uneven panels. The combined construction reduces surface vibration and helps manage moisture on metal.
Treated panels are less prone to cold-surface condensation, as reported by users, which can reduce corrosion risk and keep cavities drier. Useful on older vehicles where metal surfaces collect moisture.
