Block heat and improve your sound
Dynamat has made a name for itself by producing noise-absorbing, self-adhesive liners. Now they've taken it a step further with DynaCore, a rugged heat- and noise-absorbing material that you can use in a variety of automotive, marine, RV, and other applications.

Block heat
Dynacore is moisture- and UV-resistant and is heat-resistant up to 350 degrees. That makes it perfect for places like:

Inside car and truck hoods
Boat engine compartments
RV generator compartments
Truck or heavy equipment cabs
Anywhere you want to block heat, add Dynacore.

Improve sound
Like all DynaMat products, Dynacore is great at absorbing vibrations and making your music sound better. It offers outstanding low-frequency absorption and is lightweight, flexible, and compressible, making it perfect for putting behind speakers in the doors of your car, your boat's speaker mounts, or anywhere else where you want the best possible audio performance.
