MAT 66 ProBlack Car Sound Deadening Mat 36 sq ft — 80 mil Butyl + Foil Dampening for Doors & Floors

The MAT66 ProBlack 80 mil sound deadening mat is a self-adhesive butyl and foil damping sheet designed to reduce vibration and road-noise in vehicles with 36 sq ft of coverage.

MAT66 ProBlack combines a thick 80 mil (≈2 mm) butyl core with a foil facing to provide a user-friendly sound insulation solution for car audio enthusiasts, installers and DIYers. The product ships as 34 manageable sheets that are easy to cut and press into place; an embossed foil pattern acts as a visual guide to confirm proper adhesion and installation.

How does MAT66 improve cabin sound and vibrations?

The dense butyl layer converts panel vibrations into heat, lowering resonance from doors, floors, roofs, and trunks. The foil facing helps reflect airborne noise and provides a durable surface you can roll smooth for full contact.

• 80 mil thickness increases mass and damping on metal panels
• Butyl compound reduces structure-borne noise transmission
• Foil layer adds surface rigidity and resists moisture
• Embossed guide shows when the sheet is fully rolled for best performance

What surfaces and areas in a vehicle are best for this mat?

MAT66 is suitable for door skins, interior floor pans, trunk lids, parcel shelves and roof sections where vibration and rattles are common. Sheets are sized for convenient placement around contours and cut easily for custom fits.

• Doors: reduce panel flex and improve speaker performance
• Floors: lower road and tire noise transmitted into cabin
• Trunks and hatchbacks: cut down resonance and boom
• Roof and bulkheads: reduce wind and structural noise

How easy is installation for a DIYer and what tools are needed?

Installation is straightforward: clean the metal surface, peel the release liner, apply the sheet, and roll it smooth. While MAT66 is very sticky and user-friendly, a hand roller speeds up the process and ensures the embossed pattern flattens for correct installation.

• Sheets come in 250 x 400 mm pieces for easy handling
• No glue or heating required; press-and-roll application
• Recommended: utility knife, cleaning solvent, hand roller (not included)
• Embossed foil confirms full adhesion when flattened

What are the product specs and coverage details?

MAT66 ProBlack delivers 36 square feet (≈3.4 m²) of coverage across 34 sheets with a nominal thickness of 80 mil (2 mm). Each sheet is lightweight yet engineered to provide substantial damping per square foot for efficient results.
