Insulating cotton soundproofing for cars — multipurpose acoustic padding for bonnets, doors, roofs and boot shelves Key benefits Quieter cabin: significantly reduces engine noise, road noise and tyre rumble, giving a calmer driving environment. Improved driving comfort: lower interior noise makes it easier to concentrate, reduces fatigue and improves perceived vehicle quality. Versatile fit: designed for use on multiple vehicle panels (bonnets/hoods, doors, roofs, boot/trunk shelves) so one product works across several applications. What it is Material: insulating cotton designed for acoustic damping. Function: absorbs and blocks airborne and structure-borne noise from the engine bay and road, reducing the amount of noise that reaches the cabin. Compatibility: suitable for various car makes and models where padding can be applied to bonnets, doors, roofs and boot shelves. Performance highlights Noticeable reduction in engine and road noise when correctly installed. Helps reduce vibration and tyre rumbling transmitted through panels. Multilocation use lets you target the vehicle areas that most affect cabin noise. Practical applications (real-world scenarios) Under the bonnet/hood: line the underside of the bonnet to reduce engine and intake noise heard in the cabin while preserving access for service. Door panels: add padding to internal door shells to cut road and tyre noise and reduce vibration transmitted through the doors. Boot/trunk shelf or roof lining: apply to the boot shelf to reduce cargo or rear-suspension noise, or to the roof lining to lower overall cabin noise levels. Installation notes and safety Do not apply this insulating cotton to or near heat sources, exhaust pipes, or other hot pipe surfaces. Apply only to cool, dry surfaces and avoid areas of direct engine or exhaust heat to prevent damage. For best results, install on clean, dry panels and position the padding where noise transmission is highest. Why choose this product Simple, material-based solution to common cabin noise problems without major modifications. Multi-use design lets you address noise at several locations for cumulative benefit. Clear safety guidance included to ensure correct, long-lasting performance.
