12" x 12" x 124-mil Butyl Sound Deadening Mats

Each square measures 12” x 12” and boasts a total thickness of 124-mil (3.15mm), consisting of a robust 120-mil butyl layer and a 4-mil aluminum constraining layer. This construction results in a high composite loss factor of 0.6 @ 200hz, providing significant noise reduction. Crafted entirely in the USA, these CLD squares form an incredibly strong and permanent bond to metal, plastic, fiberglass, and more, ensuring they stay in place without peeling, sagging, or failing over time, even in extreme temperatures. They are also completely odor-free, meeting strict OEM requirements like Ford’s WSS M5G58 A2 specification, ensuring no unpleasant smells in your vehicle. Despite their thickness, the CLD Squares are surprisingly easy to install. They cut easily, lay flat, and conform well to vehicle panels thanks to the quality of the butyl. Installation is straightforward, even in a wide range of temperatures (cold or hot weather), without requiring a heat gun. Proper installation involves cleaning the surface with isopropyl alcohol, applying the material firmly, and using the ResoNix Roller for even pressure. Basic tools like shears and isopropyl alcohol are recommended for preparation and cutting. ResoNix CLD Squares offer superior single-layer performance, meaning one layer can often achieve results comparable to multiple layers of other brands. They are backed by real SAE J1637 testing data and are designed for durability and long-lasting adhesion, resisting heat, moisture, and chemicals commonly found in automotive environments.
