Product Details

DEI is known for making parts that help manage heat and sound in vehicles, and their D-Mat insulation is a prime example. This material is designed to keep your car's interior comfortable, whether you're building a show car or just want a quieter ride. It's perfect for areas like the headliner, doors, or rear bulkhead where you need to block heat without adding a lot of weight.

What's great about D-Mat is how easy it is to work with. It's only about half an inch thick, making it compressible and pliable, so you can fit it into tricky spots. It's made from a polymer blend with a scrim backing, and it can handle temperatures up to 325°F. You can expect up to a 65% reduction in heat transfer, and it also does a solid job of absorbing sound. Plus, it meets flammability ratings and resists mildew and bacteria, so it's a durable choice for most applications, except for floors where a different mat is recommended.

Installation is straightforward because you can cut it to shape easily. It's an economical way to add thermal protection and improve the acoustics inside your vehicle, especially if you're working on a project car or a vintage vehicle.
