Overview
KILMAT 80 mil 36 sqft Car Sound Deadening Mat Butyl Automotive Sound Deadener Audio Noise Insulation and dampening is an 80 mil automotive butyl and foil sound deadening material for interior vehicle surfaces. It is supplied in sheets, covers 36 square feet, and is used for automotive noise reduction and vibration dampening on doors, floors, trunks, and other metal panels.
HushMat Silencer Shop Roll is a 1/4 inch self-adhesive sound deadening foam shop roll with 20 square feet of coverage. It is described as a compressible closed cell synthetic rubber material with acoustic, sealing, and thermal insulation properties, with placement guidance for behind door trim panels and on the back of headliners.
Key takeaways
- KILMAT is a better fit for a vehicle owner planning butyl and foil vibration dampening across metal panels such as doors, floors, trunks, and other interior surfaces.
- HushMat is a better fit for a vehicle owner focused on foam-based sound absorption, sealing, and thermal insulation behind door trim panels or on the back of headliners.
- KILMAT provides 36 square feet of 80 mil aluminum-backed butyl material in sheet form.
- HushMat provides 20 square feet of 1/4 inch compressible closed cell synthetic rubber material in shop roll form.
- Both use self-adhesive installation, but KILMAT emphasizes rolling an embossed foil surface smooth, while HushMat emphasizes a form, cut, peel, and stick workflow.
What each option is best for
KILMAT is best for vehicle owners working on automotive noise reduction and vibration dampening across interior metal panels. Its butyl and aluminum construction, 80 mil thickness, embossed foil installation indicator, and 36 square feet of coverage fit projects involving measured application across doors, floors, trunks, and other metal surfaces.
HushMat is best for vehicle owners working with areas where a compressible sound deadening foam shop roll is appropriate. Its 1/4 inch closed cell synthetic rubber construction, acoustic and sealing properties, thermal insulation role, and placement guidance fit use behind door trim panels and on the back of headliners.

Installation / fitment notes
KILMAT installation centers on clean, degreased metal surfaces, careful cutting and positioning, and firm rolling. The embossed foil pattern is used as a visual installation check: it is rolled until smooth and flat to confirm proper adhesion. Gloves are recommended because the foil edges are sharp, and a well-ventilated work area is advised during surface preparation.
HushMat installation centers on a peel-and-stick workflow. It is described as simple to apply and as requiring no messy spray equipment. The roll is formed, cut, peeled, and stuck into place, with placement guidance focused on behind door trim panels and on the back of headliners.
For fitment planning, KILMAT is the more metal-panel-focused material, while HushMat is the more foam, sealing, and trim-area-focused material. The practical choice depends on whether the project area calls for butyl and foil damping on vehicle panels or compressible foam treatment behind trim and headliner surfaces.
