Dynamat Dynaliner 32x54 Self-Adhesive Sound Deadener – 1/4 in Thick, Made in USA

Overview

Dynamat Dynaliner is a lightweight, self-adhesive thermal insulation and sound deadening layer designed for automotive use. When paired with Dynamat Xtreme, it adds substantial thermal resistance and helps minimize panel resonance on floors, roofs, underhood areas, and fiberglass enclosures. This sheet is sized for broad coverage while remaining easy to handle in real-world installations.

Measured at 32 by 54 inches, the Dynaliner sheet provides 12 square feet of durable, closed-cell rubber material. The closed-cell construction helps resist moisture, so it stays steadier under carpet padding and in damp environments, reducing the risk of rust or mildew over time.

The Dynaliner backing is self-adhesive, enabling straightforward installation. Available in three thickness options—⅛, ¼, and ½ inch—you can select the thickest that your space accommodates to balance space and performance. Dynamat has manufactured this product in the USA since 1989, reflecting a long-standing commitment to quality and reliability in automotive insulation.

In practical terms, this sheet is well suited for a range of applications from floor panels to roof sections, underhood compartments, and fiberglass enclosures. It’s a solid option for car enthusiasts and professionals who value a cooler, quieter ride and dependable materials that resist moisture and wear over time.
