Dynamat 1/2" Dynaliner Thermal Barrier

The Dynamat 1/2" Dynaliner Thermal Barrier is a premium, ultra-lightweight synthetic insulation sheet designed to be installed directly on top of Dynamat Xtreme sound deadening mats. While vibration dampers neutralize structural sheet metal noise, Dynaliner targets airborne acoustics and heavy thermal transfers. This makes it an exceptional dual-purpose upgrade for sealing firewalls, under-hood areas, roofs, floors, quarter panels, and inner door cavities against extreme engine heat and road noise.

Advanced Closed-Cell Foam Engineering

• Crush & Tear Resistance: Manufactured from a highly durable synthetic foam compound engineered to resist crushing, tearing, and mechanical wear over thousands of miles of driving.

• Moisture & Oil Impermeability: Unlike traditional open-cell foams or cotton jute insulation pads, Dynaliner is completely unaffected by automotive oils and does not absorb water. This eliminates the risk of hidden mold, mildew, or trapped moisture rusting out your floorboards.

• Highest Single-Layer Heat Blocking: Provides maximum thermal insulation properties available in a single-layer synthetic foam format, helping to dramatically reduce cabin temperatures near hot exhaust tunnels and firewalls.

• Acoustic Decoupling: Works as an exceptional decoupling layer that traps and dissipates high-frequency airborne sounds, such as tire whine, wind rush, and mechanical engine thrash.

Generous 12 Sq. Ft. Sheet Real Estate

This package includes a single, extra-thick 1/2-inch utility sheet providing a total of 12 square feet of high-capacity coverage. It is perfectly portioned to tackle major problematic thermal boundaries:

• The High Firewall: Blocks extreme radiant engine heat and transmission bellhousing warmth from soaking into the driver and passenger footwells.

• The Roof Line: Stops overhead solar heat from baking the vehicle interior while dramatically reducing the sound of heavy rain hitting the roof skin.

• Under-Hood Liner: Mounts securely to the underside of the hood panel to protect external paint from engine heat blisters while deadening forward mechanical noise.

Technical Specification Matrix

🛠️ Installation Best Practice: For absolute maximum performance, apply this 1/2" Dynaliner directly over a previously installed layer of Dynamat Xtreme vibration-damping mat. Ensure the surface is free of dust or debris, peel away the release liner, and firmly press the foam down. Because this is a thick 1/2" material, verify your interior carpet kit, trim panels, or seat tracks have adequate clearance before final application.
