Self Adhesive Car Sound Deadening Mat 5mm Aluminum Foil Noise Reduction and Heat Insulation for Car Hood

Product overview This selfadhesive thermal insulation cotton panel measures 1 x 2 m (2 square meters) with a 5 mm thickness. It features a semiopen, perforated structure that absorbs incoming sound energy, reduces reflected noise and echo, and provides thermal insulation while resisting moisture. The surface is treated for flame retardancy and the core uses a closedcell foaming process to limit heat transfer. Key benefits Acoustic control: Perforated, semiopen structure absorbs sound waves to reduce interior echo and reflected noise, improving audio clarity. Strong adhesion and easy installation: Selfadhesive backing bonds firmly to a variety of vehicle surfaces including doors, hoods, bumpers and trunks for longlasting attachment. Waterproof protection: Water resistant surface helps keep interior areas dry and prevents moisture intrusion from rain or wet conditions. Thermal performance: Closedcell foaming limits heat transfer to help retain interior warmth in cold weather and reduce heat gain in hot weather. Flameretardant treated surface: Special treatment and sealed foam structure improve resistance to ignition without implying certification. Material and performance Material type: Selfadhesive thermal insulation cotton with drilled micro holes and semiopen structure for sound absorption and heat control. Size: 1 x 2 m, covering 2 square meters per panel. Thickness: 5 mm, suitable for lightweight sound damping and reflective shading applications. Structure: Perforated surface and closedcell foam core balance sound absorption with thermal insulation and moisture resistance. Compatibility and recommended uses Automotive interiors: Apply to door panels, engine hoods, trunk lids, inner roof panels and bumper interiors to reduce road and engine noise and to limit heat transfer. Light building or workshop applications: For color steel workshop roofs and walls, consider thicker options; this 5 mm panel is for simple reflective shading or secondary noise control. Typical guidance: roof insulation 2030 mm, workshop cladding 1020 mm, simple reflective shading 510 mm. Equipment enclosures: Use inside tool cabinets, machinery covers or equipment housings where moderate sound reduction and moisture resistance are needed. Installation tips Prepare the surface by cleaning and drying to ensure the adhesive bonds well. Cut to fit the target area. Peel the backing and press firmly, smoothing from one side to the other to avoid air pockets. For results on vertical or curved surfaces, apply steady pressure and allow adhesive to set before exposing to water or heavy vibration. What makes this product stand out Combines acoustic absorption and thermal insulation in a single, thin, selfadhesive panel. Perforated, semiopen design captures sound energy while the closedcell core reduces heat transfer. Easy to apply to common vehicle and light industrial surfaces for quick upgrade of noise and thermal performance. Contents One panel, 1 x 2 m, 5 mm thickness.
