Under Hood Thermal Acoustic Lining was designed primarily for engine compartments as a way to greatly reduce heat and noise with a simple and easy peel and stick application. Extreme engine heat and noise often is a problem with today's modified vehicles packed with high performance components. Made of ¾" thick, high quality, industrial acoustical grade foam with a reinforced reflective aluminum covering, Under Hood Thermal Acoustic Lining not only insulates the underside of hoods but serves as a sound deadener and thermal control while protecting paint finishes. Under Hood Thermal Acoustic Lining can also be used as noise control applications such as on generator boxes and many industrial uses including HVAC applications.
