Sound deadener mat 2mm butyl self-adhesive

The Weisshorn Sound Deadener is a professional-grade mat designed to reduce vehicle noise and vibration. Made from butyl-based rubber with an aluminium constraining surface, it absorbs sound and shock for a noticeably quieter ride.

This self-adhesive mat works across your entire vehicle—doors, boot, roof panels, or undercarriage—wherever noise and weather elements affect comfort. The 2mm thickness strikes a balance between coverage and manoeuvrability, and each sheet cuts easily to fit any shape.

Performance across conditions is reliable. The material withstands extreme temperatures from -40°C to +100°C, seals effectively against water and air ingress, and resists mineral oils and petrol. It’s eco-friendly, non-toxic, odourless, and non-corrosive. The material meets legal and statutory requirements and is flame-retardant.

Your package includes 36 sound deadener sheets (each 32cm × 50cm, totalling 5.76 square metres coverage) plus a roller tool for installation. No assembly required.

To begin, measure the areas you want to treat and start with one sheet to familiarise yourself with the application process.
