CANOPUS Sound Deadening Mat 50 mil 18 sqft Pack of 9 - High

In this review the CANOPUS Sound Deadening Mat is evaluated for drivers and installers who want a durable, high-performing solution to reduce road and trunk noise. The bottom line: this 50 mil butyl mat delivers substantial noise reduction when applied correctly and offers a sensible balance of weight and thickness for automotive insulation projects. It is best suited to hobbyists and professional installers who value long-lasting material and simple, mess-free application.

Key Features

• 50 mil thickness: The substantial thickness delivers effective vibration control and stronger damping than thinner sheets, reducing panel resonance in doors, floors and trunks.
• Butyl construction: Durable butyl composition resists degradation and remains pliable for long-term performance in automotive environments.
• Self-adhesive backing: The built-in adhesive simplifies positioning and keeps sheets in place after application when surfaces are properly prepared.
• Pack of 9 sheets: Multiple sheets allow coverage of multiple panels or targeted placement on trunk, floor, door and ceiling areas without buying individual pieces.
• Clean installation: Designed for mess-free application when surfaces are clean and rolled down firmly with a roller for full contact.

Who It's For

The CANOPUS mat is ideal for car owners improving audio quality, reducing road noise or treating visibly resonant panels; installers who need a robust 50 mil solution will appreciate the material's performance. It suits trunk, door, floor and ceiling work where thicker damping material is required to tame low-frequency vibration and chatter.

DIYers with limited time or tools should note that correct surface prep and a suitable roller are needed for best results; those seeking ultra-lightweight or decorative trim solutions may prefer thinner or fabric-based products instead.
