The Dynamat DynaDeck 12 ft. Long Roll is an ultra-durable, high-performance vinyl and thermoacoustic foam floor treatment engineered to serve as a complete carpet and padding replacement for heavy-duty automotive applications. By combining a dense acoustic mass barrier with a thermal-blocking foam core, DynaDeck effectively isolates the vehicle cabin from severe road noise, mechanical gear whine, and intense engine or exhaust heat.
Featuring a deep twist, embossed vintage texture, it delivers a rugged yet classic aesthetic that fits perfectly into the interiors of hot rods, vintage sports cars, classic trucks, Jeeps, and off-road vehicles.
Weatherproof Multi-Layer Architecture
DynaDeck relies on a dual-layer composite design to block environmental elements and acoustic transfers simultaneously:
-
High-Mass 1/8" Vinyl Barrier: Features a heavy-duty, 1 lb/sq.ft vinyl top layer that blocks low-frequency airborne sounds like exhaust drone, tire hum, and transmission clatter.
-
1/4" Closed-Cell Rubber Base: Formulated with a quarter-inch closed-cell rubber underlayment that intercepts radiant engine bay heat and exhaust system warmth before it can soak through the floorboards.
-
Total Environmental Resistance: The synthetic composition is completely weatherproof, water-resistant, oil-resistant, and wear-resistant. Because it is entirely waterproof, it will not trap moisture, mold, or rot, making it an excellent floor material for open-top utility vehicles and rugged off-road builds.
High-Capacity 54 Sq. Ft. Commercial Footprint
This industrial-sized package contains a 12-foot long by 54-inch wide seamless roll, supplying a massive 54 square feet of total material. This bulk sizing is ideal for:
-
Full Cabin Overhauls: Supplies enough continuous coverage to line the entire floor layout from the high firewall down through the cab pans of large classic trucks, multi-row SUVs, and extended cargo vans.
-
Integrated Trunk & Cargo Areas: Perfect for stretching across a vehicle's front seating row and continuing all the way back into the rear trunk floor or cargo bay area without requiring unsightly pieced seams.

🛠️ Installation Best Practice: Because DynaDeck is a thick, heavy, and structurally stable material, no adhesive is required for installation. It can be easily laid flat, trimmed to fit your floor contours, and held in place by your seat mounts and threshold trim, allowing it to be cleanly moved and reused later. For absolute optimal results and the ultimate "Dynamat Difference," install this DynaDeck roll directly over an initial layer of Dynamat Xtreme vibration-damping mat.
