Automotive insulation

ISOVER technical insulation for Automotive

Engine compartment insulation

The noise and vibrations generated by a vehicle can be unpleasant for the driver, as well as for those living and working along busy roads. Overheating can also have significant consequences for your vehicle, from evaporating essentials fluids to damaging components.

The right car insulation will help soundproof your vehicle to reduce external noise emissions, while increasing driver comfort, as well as actively reducing the negative effects of heat.
For many years, ISOVER has been working hand in hand with the automotive industry to develop state-of-the-art car insulation solutions that optimise the acoustic and thermal efficiency of your cars, trucks and buses. In partnership with leading automotive players, we design tailor-made components for engines and driver compartments based on your performance and space specifications.
  • All-in-one performance
    Designed and tested to stringent performance and quality standards, ISOVER glass wool automotive insulation combines excellent acoustic and thermal efficiency, with fire safety and mechanical durability. 
  • Superior car sound insulation
    ISOVER glass wool provides efficient acoustic absorption, especially for mid and high frequencies in line with stringent new European regulations relating to noise emissions.
  • Optimum car heat insulation
    Our glass wool products guarantee a strong barrier against heat loss to maintain the right temperature in order to optimise engine performance and lower CO2 emissions. Once installed, these products act as thermal screens to protect the vehicle parts from hot points.
  • Enhanced fire protection
    Our products are non-combustible. They help fulfil automotive standards including FMVSS302. Depending on the surface material, the products are designed to meet fire tests such as ISO 5660 and ISO 5658, as well as even more stringent tests like SS 02 48 21 (INSTA 410).
  • Lightweight materials 
    We aim to create the ideal balance in terms of cost and weight for effective sound reduction – with our solutions, you can obtain the same acoustic absorption as cotton with just half the weight.
  • Easy moulding
    Ideal for moulding, mineral wool is easy to process. Using compression moulding, die cutting and sawing, you can produce components in almost any shape with a choice of finishes. With fire-retardant, hydrophobic and oleophobic coatings, these facings help protect your engine from water and oil, as well as the risk of fire.
  • Excellent resistance and durability
    ISOVER glass wool provides excellent mechanical resistance and stability throughout the vehicle life-time including resistance to ageing and vibrations. This means you can use fewer fixing brackets compared to other types of insulation material. 
  • High temperature resistance
    ISOVER solutions are ideal for engine encapsulation to reduce noise emissions close to the source while maintaining an optimal engine temperature. Glass wool moulded parts can sustain temperatures up to 230°C.
  • Limiting your environmental impact 
    All our mineral wool insulation products are bio-soluble, 100% recyclable and made from natural raw materials. Our automotive mats are elaborated from up to 80% recycled material. ISOVER mineral wool products are also non-carcinogenic in accordance with EU criteria and certified by the EUCEB and RAL quality labels “Products made of mineral wool”.
