The pack contains 12 square feet of material in a single 54 by 32 inch sheet. Those looking to review the full specifications can view the product listing here.
Construction and Material Design
This insulation solution uses a layered composite structure that includes a heavy-duty vinyl barrier positioned between two layers of acoustic foam. The assembly is covered by an oil- and water-resisting facing. The design is described as heavy, thick, and insulating, reflecting its intended use as a dense barrier layer within vehicle interiors.
The overall thickness is listed as 0.452 inches. With a total coverage area of 12 square feet per sheet, it is configured as a single large pad rather than segmented panels. The material is identified as non-adhesive, meaning it does not include a peel-and-stick backing. In installations where adhesion is required, additional adhesive may be used separately.
Technical details indicate a model number of 21100 and a manufacturer part number of 21100. The listed item weight is 14.27 pounds, reflecting the density and mass of the composite construction.
Intended Applications
This material is positioned primarily for automotive use, particularly on floors and trunk areas. It is described as a heavyweight automotive floor insulation product intended to reduce heat and road noise. The product description identifies its role in blocking both noise and heat within vehicle interiors.
Because it is supplied as a large-format pad, it can be cut to size to accommodate different floor layouts or interior contours. Reviews commonly reference its use on floor pans, trunk areas, engine tunnels, and rear cabin sections. The non-adhesive format allows it to be positioned under carpet or other interior trim components.

Performance Characteristics
The product description highlights its use in reducing exhaust system heat and low-frequency road noise. Customer feedback repeatedly mentions noticeable reductions in road noise, vibration, and cabin sound levels when installed over appropriate surfaces. The material is also frequently described as dense and heavy, characteristics consistent with barrier-based sound insulation products.
Commonly repeated review themes include ease of cutting and handling, effectiveness in reducing unwanted sound within the cabin, and substantial weight compared to lighter foam-only solutions. Some reviewers also mention that it is heavier than expected, which aligns with its classification as a heavy-duty insulating pad.
