MAT 66 ProBlack 80 mil butyl car sound deadening mat — 36 sq ft foil-faced 2mm damping sheets

MAT66 ProBlack is an 80 mil (2 mm) self-adhesive butyl sound deadening mat designed to reduce vibration and road noise in vehicles, supplied as 36 sq ft of easy-to-install sheets.

Whether you're upgrading a car audio system or cutting cabin noise for a quieter ride, the MAT66 ProBlack combines heavy adhesive butyl with a foil finish to deliver thicker, lightweight damping where it matters. Supplied as 34 pre-cut sheets, this automotive insulation balances performance with DIY-friendly handling and includes a visible embossing indicator to confirm correct installation.

How does MAT66 ProBlack reduce noise and vibration?

The mat works by converting panel vibration into tiny amounts of heat through its dense butyl core and foil facing, lowering resonance from doors, floors, trunks and roof panels. Thicker construction (80 mil / 2 mm) increases mass and damping efficiency compared with thinner competitors, improving mid- and low-frequency control.

• 80 mil (2 mm) butyl layer for high damping performance
• Foil facing adds heat resistance and surface protection
• 0.5 lb per sq ft weight tuned for optimum effectiveness

How easy is it to install the ProBlack sheets in my car?

Sheets come pre-cut to manageable 250 x 400 mm panels so you can place and trim them without heavy tools. The strong, user-friendly adhesive sticks to cleaned bare metal and the embossed foil acts as a visual cue—smooth the embossing flat with a roller to confirm full contact and correct placement.

• 34 sheets, each 9.84 x 15.74 in (250 x 400 mm)
• Self-adhesive butyl—peel, position, press with a roller (roller sold separately)
• Embossing indicator shows completed adhesion when smoothed

Where should I apply this material on my vehicle for best results?

Target any thin metal panels that resonate: floors, trunk, doors, and roof. Apply full coverage or spot-treat high-vibration areas; combining barrier panels and coverage patterns can further improve cabin quietness and audio clarity.

• Doors and inner door skins to reduce speaker panel ringing
• Floor pans and trunk areas to minimize road and tire noise
• Roof and rear bulkhead for overall cabin dampening

What are the product specifications and installation tips?

MAT66 ProBlack is designed with measurable specs and practical installation cues so you know what you’re getting and how to install it correctly. Clean the metal surface thoroughly, remove any rust or dirt, and warm the mat slightly in cold conditions to improve adhesion.
