Innconee 23 Pcs 4-Layer 200 Mil Car Sound Deadening Mat, 5 mm 25 Sqft Automotive Butyl Insulation Sheets with Embossed Aluminum Foil, Nbr Foam, Self-Adhesive Heat Shield for Door Floor Hood Trunk — Open-Box, 5% Off

Four Layer Material: Built with embossed aluminum foil, butyl damping material, NBR foam, and self adhesive butyl backing to support vibration control, heat insulation, and cabin noise reduction in selected vehicle areas. The 200 mil thickness gives each sheet a solid feel while remaining flexible enough for curved metal panels, door skins, floor sections, trunk lids, wheel wells, firewall areas, and hood projects More DIY Coverage: Includes 23 pre cut sheets sized 15.75 x 9.84 x 0.20 inch each, providing about 25 sq ft total coverage for larger sound deadening jobs or several small repair areas. The sheet size is easy to manage during installation and works well for doors, floor sections, trunk lids, speaker areas, hood panels, roof spots, wheel wells, and other places where road noise, heat, or panel rattle may appear Self Adhesive Installation: Peel off the release liner and press the sheet onto a clean, dry metal surface after measuring and trimming to fit. The flexible panel can be cut with scissors or a utility knife, shaped around clips, holes, wires, and edges, and installed in doors, floors, hoods, roofs, trunks, and wheel wells for practical garage or workshop use with normal hand tools and careful pressure during placement Heat and Noise Control: The aluminum foil surface helps reflect radiant heat, the butyl layer helps reduce vibration at the source, and the NBR foam layer adds cushioning between panels and trim. This structure is designed for everyday drivers who want to reduce road noise, engine noise, panel buzz, and heat transfer in specific areas without replacing factory interior parts or adding heavy boards Good for Larger Projects: This 23 sheet pack is a practical choice for car owners, DIY users, and audio installers who want more coverage than a small repair set without buying a full bulk roll. Use it for doors, trunk lids, floor sections, hood panels, wheel wells, speaker areas, or several noise spots in one vehicle. Each sheet is easy to store, handle, trim, and place for home garage repairs and interior comfort upgrades
