Insulation is designed to reduce noise, control heat, and provide protection for the engine parts. The function of engine hood insulation is to dampen the noise generated by the engine. It helps to absorb and block the sound waves produced by the engine, reducing the noise that reaches the passenger compartment. This improves the overall comfort and reduces driver fatigue.Attributes:• Absorb and dampen sound waves, reducing noise levels• Dampen vibrations Applications:Insulation dampens the noise generated by the engine in the hood.
