  • Quieter Drive, Less Rattle & Vibration:Dense closed-cell foam supports sound deadening by reducing road noise, panel vibration, and interior rattles for a more comfortable ride. Noise levels can drop from ~52 dB to ~29 dB (about 50% lower). It also helps with sound dampening by absorbing both high- and low-frequency noise to keep your cabin quieter.
  • Heat-Reflective Foil Helps Reduce Heat Soak:Foil facing helps reflect radiant heat from the engine/exhaust and summer sun, supporting car insulation and improving comfort. The aluminum layer can reflect up to 95% radiant heat (lab), helping reduce heat transfer when applied to areas like hood/firewall/roof.
  • 4-Layer Build for Reliable, All-Weather Use:A foil + foam + PSA adhesive + release liner construction built for real car use. The waterproof foil surface wipes clean easily and resists everyday wear. Working temperature range: -40°F to 300°F. A dependable sound deadening material for cars built for both hot and cold conditions
  • Peel & Stick Install — Easy to Cut & Apply:Strong PSA self-adhesive backing helps it stay put once pressed firmly in place. Easy to measure, trim, and fit around curves and corners with scissors or a utility knife. Apply this sound deadener to doors, floor, trunk, wheel wells, roof, hood, firewall, cargo area and more. The waterproof adhesive helps provide a lasting hold.
