KILMAT 80 mil 36 sqft Car Sound Deadening Mat - Heavy Duty Noise

In this review the KILMAT 80 mil 36 sqft sound deadening mat is evaluated for drivers and DIY installers who want immediate, measurable noise reduction without complex tools. The bottom line: this is a user-friendly, self-adhesive butyl and foil mat that delivers strong adhesion and clear acoustic benefit where it matters most - doors, floors and trunks. The thicker 80 mil material is promoted as 1.5 times more effective than thinner sheets, and in real-world use the mat conforms to panels easily and noticeably reduces road and vibration noise.

Key Features

• 80 mil thickness: The extra thickness provides increased dampening so panels transmit less vibration into the cabin.
• Self-adhesive butyl core: A very sticky backing sticks to bare metal and irregular surfaces for a durable bond when installed correctly.
• Foil facing with embossing indicator: The foil embossing flattens out when rolled smooth, giving a visual cue that the mat is fully set and installed properly.
• 36 sqft coverage in handy sheets: Pre-sized sheets are easier to cut and place during DIY installs, reducing waste and installation time.
• Lightweight per area: At about 0.5 lb per sq ft the material adds damping without excessive weight that affects vehicle handling.
• Heat-resistant adhesion: Customers report strong adhesion even in high-heat areas, keeping the mat in place over time.

Who It's For

This mat fits owners doing an interior restoration, sound upgrades for car audio, or targeting specific noise sources like sliding doors and trunk buzz. A typical buyer is comfortable cutting sheets with basic tools and using a roller to flatten seams and the foil embossing until smooth.

It is less aimed at professional fabricators who require bonded multipiece systems with thermal barriers beyond butyl foil, or users who need a complete sound package including acoustic foam layers; those shoppers should consider multi-layer kits instead.

Pros & Cons

Pros

• Strong adhesion that holds in heat and on irregular surfaces, making long-term placement reliable.
• Notably reduces road and panel vibration noise when applied to doors, floors and trunks.
• Thicker 80 mil material increases damping efficiency while remaining manageable for DIY installs.
• Handy sheet sizes and the embossing indicator make it straightforward to install correctly.

Cons

• The material is designed for damping and will not replace layered acoustic insulation for thermal control or extreme soundproofing needs.
• Installation requires a roller and some effort to fully smooth embossing; novices may need to learn technique for best results.

Frequently Asked Questions

Will this stick to bare metal and inner door skins?
Yes; the very sticky self-adhesive butyl backing is formulated to bond to bare metal and interior panel surfaces when rolled smooth.

How do I know the mat is installed correctly?
Roll the foil face until the special embossing flattens out and becomes plain smooth; that visual cue indicates proper adhesion and installation.

Is this suitable for full cabin soundproofing?
It is best used for targeted damping of panels, doors, floors and trunks; for full cabin acoustic and thermal control, add complementary layers designed for those purposes.
