Description

The HushMat 617852 is a firewall sound dampening kit designed to reduce heat and noise within a vehicle. It features a proprietary butyl material with an aluminum backing for effective thermal insulation and sound deadening. The kit has a thickness of 0.06 inches and is engineered to withstand temperatures from -30 to over 550 degrees Fahrenheit.

Installation is simplified with a self-adhesive, peel-and-stick design, requiring no additional tools or adhesives. The material is lightweight, flexible, and can be trimmed to fit, making it suitable for direct-fit applications. HushMat claims this kit can lower interior temperatures by over 40 percent.
