Self-adhesive car sound insulation pad — closed-cell foam core with dense aluminium foil surface. Key benefits Reduces noise and vibration: closed-cell foam structure and aluminium foil layer provide effective sound insulation for vehicle cabins and equipment spaces. Controls heat transfer: reflective aluminium surface and foam core help reduce heat passage and improve thermal comfort. Moisture and vapor resistant: dense foil and closed-cell construction make the material non-absorbent with a low water absorption rate, helping prevent damp and condensation. Clean, odorless, and lightweight: foam-like performance without smell; easy to handle and adds minimal weight. Fire-resistant and waterproof: designed to resist ignition and repel water for safer, longer-lasting installation. Simple installation: available as a self-adhesive roller — cut to size, peel off the protective backing, and press into place. Material and function Core: closed-cell foam with the same insulating properties as conventional foam. Surface: dense aluminium foil that blocks water vapor and reflects heat. Adhesive: factory-applied self-adhesive layer covered by protective paper for easy, secure mounting. Performance: provides combined sound dampening and heat insulation while remaining non-absorbent and odorless. Compatibility and usage Can be trimmed to fit any shape or size; suitable for curved or flat surfaces. Designed for automotive use (doors, roofs/ceilings, bonnets, firewalls) as well as household or workshop applications (doors, ceilings, garages, indoor and outdoor walls). Multifunctional: use where both heat insulation and sound reduction are needed. Practical installation tips Clean and dry the surface before applying for best adhesion. Cut the roll to the required shape and size with scissors or a utility knife. Peel off the protective backing and press firmly, removing any air pockets. Use scenarios 1) Car cabin improvement: Line the inner roof and door panels to reduce road and wind noise and improve temperature comfort during drives. 2) Engine bay / bonnet and firewall: Apply to the underside of the bonnet and firewall to reduce engine noise reaching the cabin and to add a heat-reflective barrier. 3) Home garage or workshop: Mount on garage doors or interior walls and ceilings to reduce echo, control temperature, and protect against moisture. What makes it stand out Combines foam-like sound insulation with a vapor-resistant aluminium surface for reliable, long-lasting performance. Odorless, lightweight, fireproof, and waterproof — suitable for a wide range of automotive and building applications. Easy, mess-free installation with self-adhesive backing and customizable cut-to-fit format.
