Car insulation

The automotive market is a dynamic and rapidly evolving industry characterized by technological advancements, changing consumer preferences, and regulatory shifts. The key trends in the automotive market include the shift towards electrification, autonomous driving, connectivity, sustainability, shared mobility, and advanced manufacturing technologies.

As these transformative trends shape the automotive market, the role of automotive insulation becomes increasingly crucial in enhancing vehicle efficiency, comfort, and safety, ensuring that modern cars meet the growing demands for performance and sustainability.

With advancements in material science and manufacturing processes, there's a growing focus in the global market on developing lightweight and sustainable insulation materials that offer superior performance in terms of thermal and acoustic insulation.

For many years, Isover has been working hand in hand with the automotive industry pioneers to develop effective vehicle insulation solutions that optimise the acoustic and thermal efficiency of cars, trucks and buses.

What is the purpose of automotive insulation?

The purpose of automotive insulation in the engine and battery compartments is to ensure optimal vehicle safety, efficiency, and performance. 

In the engine compartment, ISOVER's specialized insulation solutions manage the intense heat generated during operation, protecting sensitive components from overheating and ensuring smooth performance. This insulation also dampens engine noise, contributing to a quieter and more comfortable driving experience. 

For electric vehicles, ISOVER's advanced battery insulation addresses the critical thermal challenges, maintaining optimal battery temperatures to enhance efficiency and lifespan. Additionally, this insulation provides crucial fire protection, mitigating risks associated with thermal runaway and ensuring the safety of passengers and the vehicle. 

By focusing on these critical areas, ISOVER's automotive insulation solutions play a pivotal role in the reliability and longevity of modern vehicles.

Neglecting to insulate critical areas in a vehicle such as the engine and battery compartments in vehicles can pose significant risks. Firstly, in the absence of proper insulation, engine compartments are susceptible to overheating, which not only compromises the performance and longevity of vehicle components but also increases the likelihood of engine-related malfunctions or failures. 

Moreover, without adequate insulation, batteries in electric vehicles are prone to temperature fluctuations that can negatively impact their efficiency and lifespan. Additionally, uninsulated battery compartments pose a heightened risk of thermal runaway events, potentially leading to battery fires or explosions, posing severe safety hazards to occupants and surrounding areas. 

Proper insulation of these two components is essential to mitigate these risks and ensure the safe and reliable operation of vehicles.
 

Key benefits of automotive insulation
 

• Noise Reduction: One of the primary benefits of automotive insulation is its ability to reduce noise. This involves both reducing external noise, such as road vibrations, engine hum and wind resistance, and also limiting the noise emissions of the vehicle itself to its environment. By reducing noise levels within the cabin, insulation creates a quieter and more peaceful environment for both driver and passengers. At the same time, sound insulation helps reduce environmental noise pollution and comply with acoustic regulations.
• Thermal Control: Automotive insulation helps regulate interior temperatures by preventing heat transfer between the inside and outside of the vehicle leading to improved energy efficiency and fuel economy. 
• Comfort Enhancement: By minimising noise and maintaining optimal temperatures, automotive insulation significantly enhances overall comfort during driving.
• Safety: Proper insulation materials in vehicles are designed to meet stringent fire safety standards to minimise the risk of fire hazards, especially in areas like the engine compartment and battery housing.

Trust Isover automotive insulation solutions

In partnership with leading automotive players, we, at Isover, design tailor-made components for engines and driver compartments based on your performance and space specifications, offering a range of benefits that can make the driving experience much better:
 

1. All-in-one performance: Designed and tested to stringent performance and quality standards, Isover automotive insulation combines excellent acoustic and thermal efficiency, with fire safety and mechanical durability. 
2. Superior car sound insulation: Our automotive insulation solutions provide efficient acoustic absorption, especially for mid and high frequencies in line with stringent new European regulations relating to noise emissions.
3. Optimum car heat insulation: Our insulation solutions 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.
4. 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).
5. 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.
6. 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.
7. Excellent resistance and durability: Our car insulation solutions provide 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. 
8. High temperature resistance: Our automotive insulation 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.
9. 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”.

Our comprehensive car insulation solutions are designed to meet the diverse needs of various vehicles, including cars, SUVs, pickups, and construction vehicles. These solutions offer high-quality sound and thermal insulation, ensuring a quiet and comfortable driving experience while also maintaining the optimal temperature within the vehicle. Additionally, our products are designed with fire protection in mind, providing an extra layer of safety for all occupants, regardless of the vehicle type.

Why should the vehicles of the future be insulated?

We conducted an interview with Prof. Dr. Stefan Bratzel from the Center of Automotive Management (CAM) to discuss the critical role of vehicle sound and heat insulation. The interview explores the importance of addressing noise and thermal challenges in vehicle development, particularly with the increasing emphasis on electric vehicles and the need for fire-safe, sustainable materials like thermoformable glass wool.
