This 50-sheet pack covers 4.7 sq.m (50 sq.ft), with each sheet measuring 375 x 250mm and a total pack weight of 12.5kg.

Who it suits

Our tech experts advise
Clean bare interior sheet metal before applying — peel, position and press firmly for good contact. The Hex embossing keeps the mat flexible and helps it conform to curved panels without creasing. Rated from -40°C to +120°C, it is fire retardant and water and oil resistant, tested to ISO 3795:1989. For a more complete acoustic result, layer Dodo DEAD-EZY 5mm insulation roll over the deadening.

Frequently Asked Questions
Q: How much sound deadening do I need for my car?
A: As a guide, a pair of front doors takes around 1 to 1.5 square metres, and a full car between 4 and 6 square metres depending on coverage. The sheet coverage for this product is listed in the Specification tab.
Q: Where should I apply sound deadening first?
A: Doors give the biggest gain for both road noise and speaker performance, followed by the boot floor and wheel arches. Even a doors-only install noticeably tightens speaker bass.
Q: Is sound deadening difficult to fit myself?
A: It is one of the more DIY-friendly upgrades: panels are cut to shape, peeled and rolled firmly onto clean metal. A roller tool and panel removal tools make the job much easier, or CEN can carry out installation from our Nottingham premises.
Q: Will sound deadening improve my audio system?
A: Yes. Deadening the doors reduces panel resonance so speakers produce cleaner, tighter bass, and lowering road noise means you hear more detail at normal volumes.
Q: How much area does the Dodo Mat DEADN Hex 50 sheet pack cover?
A: The pack contains 50 sheets, each 375 x 250mm, covering 50 sq.ft (4.7 sq.m) in total. The full pack weighs 12.5kg.
Q: How thick is Dodo Mat DEADN Hex and what is it made from?
A: Each sheet is 1.8mm thick, with a high grade butyl core, a Hex embossed aluminium top sheet and a strong self-adhesive backing.
Q: Is Dodo Mat DEADN Hex heat and fire resistant?
A: Yes. It is fire retardant and heat resistant from -40°C to +120°C, flammability tested for vehicle interiors to ISO 3795:1989, and fully water and oil resistant.
