KILMAT 50 mil butyl sound deadening mat is a self-adhesive automotive insulation sheet designed to reduce road noise, absorb vibration, and improve in-car audio quality.

Engineered for do-it-yourself installers and professional shops alike, this 25 square-foot pack of KILMAT sheets combines a 1.3 mm (50 mil) butyl core with a foil surface to add mass and dampening where cars need it most. Lightweight yet effective, each square foot weighs about 0.35 lb, giving a balance of manageable handling and notable noise control without adding excessive bulk.

How will this mat affect road and panel noise?

The butyl core converts vibration energy into negligible heat while the foil layer adds stiffness to panels, together lowering rattles and airborne noise. Expect a quieter cabin and a firmer feeling from doors and floors after installation.

  • 50 mil (1.3 mm) thickness reduces mid-frequency panel resonance.
  • Butyl compound absorbs vibrations for less rattle.
  • Foil facing increases surface stiffness and blocks some airborne sound.

Is this product easy for DIY installation?

Yes — KILMAT sheets are supplied with a strong peel-and-stick adhesive and pre-sized panels that are simple to cut and press into place. The material remains pliable enough to conform to typical vehicle contours while offering a tactile feedback feature to confirm full adhesion.

  • Self-adhesive backing adheres to clean, dry metal surfaces.
  • Hand-tearable/trim-to-fit sheets for doors, floors, or trunks.
  • Embossed foil flattens when properly rolled, indicating correct installation.

What areas of a vehicle benefit most from this mat?

Install KILMAT on inner doors, floors, roof sections, trunk walls, and rear wheel wells to cut vibration and reduce transmitted noise. Targeting large flat panels yields the quickest perceptible improvements.

  • Floor pans and under-seat areas for road and tire noise reduction.
  • Door skins to eliminate flutter and improve speaker performance.
  • Trunks and rear decks to minimize resonance and bass bleed.

Will this add a lot of weight or change vehicle dimensions?

The mat is engineered to be lightweight for its damping performance, at roughly 0.35 lb per square foot, so a full 25 sq.ft. kit adds noticeable mass where applied but won’t substantially change vehicle clearance or handling when used as directed.

  • Total coverage: 25 square feet per kit.
  • Nominal thickness: 50 mil (1.3 mm) for a slim, effective profile.
  • Weight: ~0.35 lbs per sq.ft. (≈1.75 kg/m²) for efficient sound control with minimal bulk.

Who is this for: KILMAT 50 mil sound deadening mats are aimed at car owners, audio enthusiasts, and installers who want a practical, professional-feeling solution to reduce cabin noise and improve audio performance without heavy, hard-to-handle materials. It’s ideal for DIY upgrades on doors, floors, trunks, and wheel wells, as well as for technicians seeking a reliable, easy-to-install dampening product for everyday vehicles and custom audio projects.
