KILMAT Butyl Car Sound Deadening Mat 50 mil (1.3 mm) — 50 sq.ft Foil‑Backed Dampening for Road Noise & Panel Vibration

KILMAT 50 mil 50 sq.ft butyl sound deadening mat is a self-adhesive automotive damping sheet designed to cut road noise, stop panel vibration, and improve in-car audio clarity.

This 1.3 mm (50 mil) automotive-grade butyl mat with foil facing provides lightweight, high-density sound control across 50 square feet of coverage. Made for DIY installers and professional fitters alike, the sheets are sized for easy cutting and handling; the foil embossing acts as an installation indicator, so you know when each panel is rolled smooth and bonded correctly. KILMAT balances mass, tack, and flexibility to reduce rattle and lower interior noise without adding unnecessary bulk or weight to your vehicle.

How does KILMAT reduce road noise and vibration?

The mat dampens metal panels by converting vibrational energy into heat and by adding mass to surfaces that otherwise amplify engine, road, and tire noise. Installed on doors, floors, roof, and trunk panels, it prevents resonance and reduces the audible transmission of low- and mid-frequency sounds that cause rattles.

• 50 mil (1.3 mm) butyl layer for effective damping on sheet metal.
• Foil facing reflects some high-frequency noise and eases rolling during installation.
• 0.35 lbs per sq.ft density provides attenuation without heavy weight penalties.

Where should I apply these sheets for the best results?

Place the sheets on large flat or gently curved metal surfaces to stop panels from ringing: doors, floor pans, firewalls, trunk lids, and roof skins are common targets. Focus on driver and passenger doors plus floor areas under seats first for immediate improvement in cabin quiet and sound system performance.

• Cover door inner skins and around speaker locations to reduce vibration.
• Apply to floor pans beneath carpeting to block road and tire noise.
• Use on trunk lid and spare wheel well to minimize booming and resonance.

How easy is it to install KILMAT for a DIY project?

Installation is straightforward: peel the liner, place the sheet, and use a roller to press the foil until the embossed pattern smooths out—this indicates full contact. Sheets are provided in manageable sizes so cutting with a utility knife or scissors is simple, and the aggressive adhesive bonds quickly to clean, dry metal.

• Pre-cut nominal sheet size 250 × 400 mm (9.8 × 15.7 in) for easy handling.
• 47 sheets total for 50 sq.ft coverage—ideal for phased installs.
• Embossed foil indicates correct adhesion when fully rolled flat.

What are the product specifications and safety notes?

The mat is a butyl-based, self-adhesive soundproofing product with an aluminum foil face; total delivered area is 50 sq.ft (4.7 sqm), and each nominal sheet is 9.8 × 15.7 inches. Keep surfaces clean, oil-free, and dry before application; warm the mat slightly in cold conditions to improve pliability and adhesion. Avoid exposure to open flame and follow local disposal guidelines for adhesive-backed materials.

• Thickness: 50 mil (1.3 mm); total weight approx. 0.35 lbs per sq.ft.
• Coverage: 50 sq.ft / 4.7 sq.m; 47 sheets per pack.
• Sheet size: 250 × 400 mm (9.8 × 15.7 in); foil-faced butyl construction.

Who is this for? KILMAT 50 mil sound deadening mat is aimed at vehicle owners, car audio enthusiasts, and installers seeking a balance of effectiveness and ease-of-use. It's suitable for weekend DIYers upgrading cabin quiet or sound staging and for professionals needing consistent, lightweight damping material that speeds installation and provides a clear visual cue when panels are fully adhered.
