About the Dynamat 11905
From our tech experts at CEN
Acoustic absorbing foam, for soaking up the reflections a hard-surfaced vehicle interior creates from Dynamat.
Who it suits
Van and camper conversions, and anywhere road and wind noise is the problem rather than panel resonance. Foam and butyl do different jobs and work best together.
Our tech experts advise
Coverage matters more than thickness: treat the outer skin behind the speaker first, then the inner. It is messy, fiddly work inside a door, which is why we normally do it as part of an install rather than sell it as a weekend job. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

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 does the Dynamat Hoodliner protect the bonnet paint?
A: Its reinforced aluminised skin reflects up to 97% of radiant engine heat and forms a water/oil barrier, helping protect the paint finish on the bonnet.
Q: Should the Hoodliner be fitted over Dynamat Xtreme?
A: For maximum noise control, Dynamat recommends applying the Hoodliner over Dynamat Xtreme.
Q: How thick is the Dynamat Hoodliner?
A: The Hoodliner is 19mm (3/4 inch) thick, supplied as one 813mm x 1372mm (32 x 54 inch) sheet.
