MAT66 ProBlack 80 mil Car Sound Deadening Mat - Thick Butyl Insulation

In this review of the MAT66 ProBlack 80 mil sound deadening mat, the bottom line is simple: it is a practical, DIY-friendly solution for drivers who want a noticeable reduction in road noise and improved in-car audio without professional installation. The material is thicker than many budget alternatives, and that extra 1.5x thickness translates to firmer damping of vibrations and better low-frequency control. Installers who value strong self-adhesion and easy cutting will find it an especially sensible purchase.

Key Features

• 80 mil thickness: The greater material thickness delivers stronger vibration damping and improved insulation for cleaner cabin sound.
• Butyl and foil construction: The butyl core with foil facing resists temperature changes while providing a durable barrier for sound and heat.
• Very sticky self-adhesive: Strong tack simplifies application and keeps sheets firmly in place on metal surfaces once applied.
• Handy sheet size: Precut sheets make measuring and trimming easier for DIY fits around doors, floors and panels.
• Installation indicator: Embossing on the foil flattens when rolled out correctly, giving a clear visual cue that the mat is fully adhered.
• Lightweight per area: At roughly 0.5 lb per sq ft, the mat balances insulation performance with manageable handling during installation.

Who It's For

This mat is best for car owners and audio enthusiasts who want an effective, hands-on way to reduce road noise and improve music clarity without paying for professional installation. It fits well for owners of older vehicles where factory sound insulation has degraded or for anyone adding aftermarket speakers and seeking cleaner bass response.

It is less appropriate for users who need soundproofing that doubles as heavy structural reinforcement or for installs demanding specialized adhesives or composite layers beyond butyl and foil. If you require an ultra-thin layer for tight panel clearances, consider a thinner product instead.

Pros & Cons

Pros

• Very sticky adhesive makes installation quick and ensures long-term hold on metal surfaces.
• Thicker 80 mil construction yields better vibration dampening and audible noise reduction compared with thinner mats.
• Embossed foil gives an easy visual check for correct installation.
• Sheets are easy to cut and position, which speeds up DIY projects.

Cons

• Some users report a mixed smell on first unpacking, so allow airing time after install.
• At 80 mil the material is thicker and may be harder to fit in extremely tight or complex trim areas.

Our Verdict

The MAT66 ProBlack 80 mil mat is a strong choice for DIYers who want substantial noise reduction and improved audio performance without complex products or adhesives. Its thicker butyl construction, reliable stickiness and installation indicator make it a good value for drivers upgrading insulation in older cars or adding aftermarket audio. Allow for airing if odor is a concern and expect a bit more effort when fitting very tight areas.

Frequently Asked Questions

Will this mat stick to car metal panels?
Yes. The product uses a very sticky self-adhesive butyl layer designed to bond to bare metal and factory panel surfaces once the foil is rolled flat.

How much area does one pack cover?
One pack provides 18 sq ft of coverage, sold in handy sheets for cutting and trimming.

Is the smell a permanent issue?
Smell reactions are mixed; most users report the odor fades after installation and ventilation, so allow time to air the vehicle if concerned.
