EFS™ Thermal Solutions
Battery Thermal Insulation
Outside influences like adverse exterior temperatures mean that active thermal management systems must consume a substantial amount of energy to ensure optimal battery temperatures. Our Battery Thermal Insulation protects the battery from such a harsh environment and improves the range of the battery-powered vehicle.
Battery Thermal Insulation comprises three to six layers, based on the application and flammability requirements (UL94 V0/Non-Combustible).
- Maintains battery temperature for optimal battery efficiency and life
- Available as flat-cut and 3D thermoformed parts
- Can be installed using current installation process i.e. pressure adhesives / mechanical studs
- Excellent heat strength resistance
- Non-burning
- Non-stretchable
- Non-toxic
- Excellent chemical resistance against grease, water, and mud
EFS Battery Thermal Insulation
- Passive battery insulation for maintaining battery temperature (which heats up to 70ºC) for optimal battery life and efficiency.

Engine Bay Heat and Noise Shields
The regulations for noise emissions from the engine towards its surroundings are becoming more stringent each year. The target is to reduce noise emitted by transportation. Reducing engine bay noise at the source also means a cost reduction for cities, as they no longer need to install noise management walls.
Managing both heat and noise is a specialty of L&L Products. Our Engine Bay Heat and Noise Shields comprise three to six layers, based on customers’ application needs in terms of noise reduction, heat and flammability requirements (e.g. UL94 V0/Non-Combustible). Outside of the target performance, Engine Bay Heat and Noise Shields offer excellent resistance against chemicals, cleaning agents, grease, water, stone chip, and mud and can be cleaned by a power wash.
- Comprises three to six layers
- Parts are available as flat-cut and/or as 3D thermoformed to enable any shape
- Can be installed using the customer’s current installation process, i.e. with pressure adhesives and mechanical studs
- Non-stretchable
- Excellent resistance against chemicals, cleaning agents, grease, water, stone chip and mud
- Can be cleaned by a power wash
EFS Acoustic Firewall Solutions (Inner and Outer)
- Reducing in-cabin noise with a multilayer approach that covers a broad frequency range.

Heat Shield
Our Heat Shield is a non-stretchable, high-temperature resistant insulation solution for exhaust thermal management applications. It comprises of three to eight layers depending on the application and functional requirements and is available in both rigid (metallic solution) and flexible casings. Heat Shields demonstrate excellent heat-strength resistance, improved heat / temperature retention, and are non-burning.
Our Heat Shield allows OEMs to achieve Euro IV or VI compliance (depending on region) and are non-toxic with excellent chemical resistance against grease, water, and mud.
- 3 to 8 layered constructions (flexible/metallic)
- Application temperature ranges from -30°C to +850°C, during continuous exposure at 800°C.
- Thermal conductivity, k-value in range of 0.03 to 0.036 w/mk @ 22.5 °C
- Delta T across thickness in range of 75 – 85%
- Delta T across length 1m to 3m, in range of 3°C to 15°C (depending upon construction & functional requirements)
- Improves flex properties versus traditional solutions
- Anti-friction and air-pockets to assist in circulation / retention of hot air
- Excellent heat strength resistance
- Non-burning
- Non-toxic
- Excellent chemical resistance against grease, water, and mud
EFS Thermal Flexible Heat Shield
- High temperature capable flexible insulation solution for exhaust thermal management applications.

Under-Hood and Under-Floor Thermal Insulation
As EURO-VI engines generally run at higher temperatures compared to preceding engines, L&L Products engineers a custom insulation solution that works well for under-hood and under-floor applications. Our Under-Hood and Under-Floor Thermal Insulation maintains more of a steady temperature within ambient +2°C (35°F) in the driver’s cabin for best possible driver and passenger comfort.
Under-Hood and Under-floor Thermal Insulation comprises of four to six layers, based on the application and functional requirements, temperatures from the engine bay / EATS system ranges from 150°C (302°F) to as high as 400°C (750°F) when entering the cab. Parts are available as flat-cut and/or as 3D thermoformed to enable any shape.
- Comprises of four to six layers
- Designed to maintain cabin temperature within ambient +2°C for enhanced driver comfort
- Available as flat-cut and 3D thermoformed parts
- Can be installed using current installation process i.e. pressure adhesives / mechanical studs
- Excellent heat strength resistant
- Non-burning
- Non-stretchable
- Non-toxic
- Excellent chemical resistance against grease, water, and mud
EFS Thermal Engine Compartment Insulators
- High-temperature capable insulation solution for under hood and under floor applications.
