From our tech experts at CEN
The Comfort Mat Vibration Deadening Atom Bomb 4.2mm is a professional-grade, multi-layer bitumen-mastic mat sold as a pack of 5 sheets, each measuring 500 x 700mm. At 4.2mm thick, it has a mechanical loss factor of 0.6 and adhesion of 11 N/cm, making it suited to high-vibration areas including the floor, engine firewall and wheel arches. Each sheet weighs 2.4kg.
Who it suits
It suits anyone fitting a first-layer vibration deadener where road or engine noise is a significant problem. Those who need more sheets for a larger area may prefer the thinner Comfort Mat Vespa 2.5mm (10 sheets).
Our tech experts advise
The material must be warmed to 50°C before fitting to activate the adhesive properly. Five sheets provide approximately 1.75m² of coverage, so measure your target areas before ordering. For a complete door treatment, see the Comfort Mat Door Kit Essential 3 in 1.

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 a pack of Comfort Mat Pulsar cover?
A: Each sheet measures 500 x 320 mm (0.16 square metres), so the pack of 15 sheets covers about 2.4 square metres.
Q: Do I need another layer on top of Pulsar?
A: Pulsar is designed to be used as a single layer. It combines anti-vibration damping and sound insulation in one 5 mm sheet, made up of a 100 micron foil, 5 mm mastic with foamed granules and an adhesive layer.
Q: Where can Comfort Mat Pulsar be fitted?
A: It is suited to doors, roof, bonnet, boot lid, boot and the floor under the rear seats, typically areas with medium to high vibration and noise loads.
