Choosing your engine insulation
Opting for adapted, high-quality engine insulation materials for your engine compartment can significantly reduce many of these disadvantages :
- Engine compartment insulation plays an important role in keeping heat and noise in the engine bay from reaching the interior of the vehicle.
- Engine compartment heat insulation protects drivers, operators, and passengers from high temperatures, which may damage on-board electronics like GPS tracking systems.
- Engine compartment sound insulation dampens damaging sound-induced vibrations and protects from decibel levels that may be harmful to human hearing.
Why choose ISOVER engine insulation?
Working closely with key players in the automotive industry for many years, ISOVER has developed high-quality glasswool products that optimise acoustic and thermal efficiency in cars, trucks, heavy, vehicles and buses.
-
Acoustic insulation
ISOVER glasswool actively reduces noise especially for mid and high frequencies. -
Lightweight performance
Glasswool products achieve the same level of acoustic absorption as cotton for just half the weight. -
Fire protection
Our non-combustible products help you fulfil automotive fire safety standards like FMVSS302. -
Easy to mould
Ideal for moulding with different coatings to optimise the performance of the finished insulation part. -
Mechanical strength & durability
Moulded parts with ISOVER glasswool maintain excellent mechanical resistance and stability throughout the vehicle lifetime. -
Temperature resistance
Ideal for engine encapsulation to reduce noise emissions close to the source while maintaining an optimal engine temperature. -
Thermal insulation
Guarantee a strong barrier against heat loss to maintain the right temperature, optimise engine performance and reduce CO² emissions -
Environmental impact
Our glasswool is bio soluble, 100% recyclable and made almost entirely of natural raw materials. Our automotive felts are made from 80% recycled material.

Our businesses are represented worldwide covering local products, services and other information.
