Dynaliner 1/2"
Dynaliner is a lightweight automotive thermal insulator, ideal for use on top of Dynamat Xtreme. It uses soft, self-adhesive closed cell rubber foam with thousands of tightly packed cells, giving it near-zero air infiltration. This is the key to its ability to block heat and resist oil and water. Because it will not hold water, it will not promote rust or mildew. It is also crush and tear resistant, making it long lasting.
The 1/2" thickness is the thickest Dynaliner option and is best suited to floors, roofs, underhood areas and fibreglass enclosures. Combined with Dynamat Xtreme, Dynaliner nearly doubles total thermal resistance. It is suitable for the roof, firewall, floor, quarter panels, doors and under the bonnet. Use the thickest option your available space will allow.

About the Dynamat 11103
From our tech experts at CEN
Acoustic absorbing foam, for soaking up the reflections a hard-surfaced vehicle interior creates, 12mm 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: Which Dynaliner thickness should I choose?
A: Use the thickest one your space allows. Dynamat recommends 1/8" for under trim (doors) and fibreglass enclosures, and 1/4" or 1/2" for floor, roof, underhood and fibreglass enclosures.
Q: Should Dynaliner be fitted on its own or over Dynamat?
A: Dynaliner is designed to go on top of Dynamat Xtreme. Combined with Dynamat it nearly doubles the total thermal resistance.
