The Dynamat DynaDeck 3 ft. Long Roll is an ultra-durable vinyl and thermoacoustic foam carpet and padding replacement engineered to block intense noise and heat in automotive applications. By combining a dense acoustic mass barrier with an insulated closed-cell foam core, DynaDeck effectively isolates the vehicle cabin from severe road noise and exhaust system heat.
Featuring a deep twist, embossed vintage texture, it delivers a rugged yet classic aesthetic that fits perfectly into hot rods, classic sports cars, trucks, Jeeps, and off-road vehicles.
Weatherproof Multi-Layer Architecture
DynaDeck relies on a specialized dual-layer composite design to simultaneously block environmental elements and acoustic transfers:
-
High-Mass 1/8" Vinyl Barrier: Features a heavy-duty, 1 lb/sq.ft vinyl top layer (1/8 inch thick) that acts as a dense barrier to quiet harsh road noise.
-
1/4" Closed-Cell Rubber Base: Formulated with a quarter-inch closed-cell rubber underlayment that intercepts radiant engine and exhaust heat before it bakes your floorboards.
-
Total Environmental Resistance: The synthetic composition is completely weatherproof, waterproof, water-resistant, oil-resistant, and wear-resistant. Because it will not trap moisture, mold, or rot, it is the ideal choice for vehicles where a highly durable, waterproof floor material is desired.
Targeted 13.5 Sq. Ft. Small-Format Footprint
This package contains a single 3-foot long by 54-inch wide roll, supplying a total of 13.5 square feet of material. This compact roll size is perfectly optimized for:
-
Spot Damping & Floor Patching: Provides the exact amount of material needed to insulate isolated high-heat areas, such as directly over a transmission tunnel or a driver-side footwell.
-
Compact Trunk Floors: Ideal for custom-fitting across the rear trunk floor or cargo area of smaller sports cars, coupes, or compact vintage buggies.
-
Project Add-Ons: Perfect when you need a small amount of extra material to top off a larger installation without purchasing a full-length commercial roll.

🛠️ Installation Best Practice: Because DynaDeck is a thick, heavy, and structurally stable material, no adhesive is needed for installation. It can be laid flat, trimmed to fit your specific floor contours, and held down by your seats and threshold trim—allowing it to be easily moved and reused later if necessary. For absolute optimal results, install your DynaDeck roll directly over an initial layer of Dynamat Xtreme vibration-damping mat.
