Dynamat 11103 12mm Dynaliner High Performance Insulation Matting

Dynamat 11103 Dynaliner 12mm High Performance Thermal and Acoustic Insulation Matting One 813mm x 1372mm Self-Adhesive Closed Cell Rubber Sheet Maximum Thermal Resistance 1.11sqm Coverage

The Dynamat 11103 is one 813mm x 1372mm (32" x 54") sheet of Dynaliner at 12.7mm (1/2") thickness, giving 1.11sqm (12 sq ft) of coverage. The thickest option in the Dynaliner range, providing maximum thermal resistance for applications where panel clearance allows a full 12.7mm insulation layer.

Product overview

Dynaliner is a self-adhesive closed cell rubber thermal and acoustic insulator designed to be used on top of Dynamat Xtreme for combined vibration damping and heat blocking. As CLDs and thermal insulators work better the thicker they are, the 11103 at 12.7mm delivers the highest thermal performance of the Dynaliner range and should be used in any application where the available clearance can accommodate it. The tightly packed closed cell structure gives near-zero air infiltration for maximum heat blocking, and its resistance to oil and water absorption means it will not promote rust or mildew the way conventional under-carpet padding can. Crush and tear resistant, lightweight and flexible, the 11103 suits roof, firewall, floor, quarter panel, and door applications.

Frequently asked questions

How does the 11103 compare to the other Dynaliner thicknesses?

The 11103 is 12.7mm (1/2") thick, making it the thickest option in the Dynaliner range. The 11102 is 6.35mm (1/4") and the 11101 is 3.175mm (1/8"). All three share the same 813mm x 1372mm sheet size and 1.11sqm coverage. Dynamat recommends using the thickest version that the available panel clearance will allow.

What is Dynaliner and how does it work with Dynamat Xtreme?

Dynaliner is a closed cell rubber thermal and acoustic insulator. Dynamat Xtreme is applied to the bare metal panel first to damp vibration, then Dynaliner is applied on top to add thermal insulation and acoustic absorption. Combined, the two layers nearly double total thermal resistance compared to Dynamat alone.

Why does Dynaliner not promote rust or mildew?

Dynaliner's closed cell structure has near-zero air infiltration, so water cannot be absorbed into the material. Unlike conventional under-carpet padding that traps moisture against the panel, Dynaliner stays dry and does not create conditions for rust or mildew.

What areas of the vehicle is the 11103 suited to?

The 11103 is suited to roof, firewall, floor, quarter panels, doors, and under-hood areas where a 12.7mm layer of thermal and acoustic insulation fits within the available panel clearance.

Does the 11103 require surface preparation?

No. The self-adhesive backing bonds directly to Dynamat Xtreme or bare panel surfaces without adhesive preparation. A Dynaroller tool is recommended to ensure complete contact.
