KILMAT 50 mil 50 sqft Car Sound Deadening Mat - Cuts Road Noise

In this review the KILMAT 50 mil 50 sqft Car Sound Deadening Mat is evaluated for DIY installers and drivers who want a practical way to cut road and engine noise. The bottom line: this butyl and foil mat offers effective damping with a heavy, tacky adhesive that makes it straightforward to fit in doors, floors, and trunks. The reviewer found the material easy to cut and apply, and the embossed foil indicator gives a clear visual cue when a panel has been rolled smooth for a professional result.

Key Features

• 50 mil thickness: The 1.3 mm thickness provides substantial mass to reduce vibration and rattle without excessive bulk.
• Self-adhesive butyl: Very sticky backing makes installation possible without extra glue, sticking firmly to clean metal and trim surfaces.
• Foil face with embossing: The foil shows an embossing that flattens as you roll it, acting as an installation indicator so you can confirm full adhesion.
• Hands-on DIY sizing: Sheets come in manageable sizes that are easy to cut with a razor or shears for custom fits around panels and cavities.
• Lightweight per area: At about 0.35 lb per sq ft the material balances damping performance with a relatively light added weight for the vehicle.
• 50 sq ft coverage: The kit covers a full 50 sq ft so it is useful for multiple doors, a trunk area, or partial floor coverage in one purchase.

Who It's For

This product is aimed at car owners doing their own audio or NVH upgrades who want a straightforward, effective sound deadener that installs without special adhesives or tools. It is ideal for people damping door panels, trunks, and floors to reduce road noise, rattles, and improve stereo bass performance.

Those who should look elsewhere are installers who need extreme mass-loading for professional race or heavy commercial applications, or anyone who prefers spray-on or multi-layer composite systems; this butyl-and-foil mat is tuned for consumer-level damping and ease of installation rather than maximum possible mass.

Pros & Cons

Pros

• Very sticky adhesive makes panels stay put and simplifies DIY installs.
• Effective at reducing road and engine noise when applied over common panel areas.
• Sheets are easy to cut and shape, and the embossing gives a clear installation cue.
• Good coverage with 50 sq ft supplied, offering solid value for multiple areas.

Cons

• At 50 mil it is not the heaviest available option, so extreme soundproofing projects may require additional layers or denser products.
• Adhesion depends on surface prep; dirty or oily metal will reduce stickiness and may need cleaning first.

Frequently Asked Questions

Will this stick to painted metal?
Yes, but for best adhesion clean paint of grease and dirt first; the adhesive bonds best to clean, dry surfaces.

Can it be cut to fit tight spaces?
Yes, sheets are easy to trim with a razor or shears and can be shaped to fit door cavities and panels.

Is one 50 sq ft pack enough for a full car?
It depends on coverage goals; 50 sq ft covers doors and some floor or trunk areas but full-floor plus doors may require additional packs.
