The present invention relates to an insulation for a wheel house of a car, in which a coating layer is formed on the surface of a compression felt layer, and can improve durability and noise performance by preventing damage to the wheel house insulation through the coating layer for blocking scattering water or foreign materials due to rotation of a tire and preventing absorption of rainwater, etc. into the wheel house insulation. In particular, the insulation for a wheel house of a car can minimize increases in the weight thereof and improve noise performance and durability thereof by using low density polyethylene (LDPE) as a material for the coating layer, and can be manufactured at low costs and safely used. In addition, the insulation for a wheel house of a car can minimize the total weight thereof by forming the coating layer only on the insulation surface facing the tire when being mounted in the wheel house, and can increase the effect of blocking foreign materials and rainwater scattered from the tire during driving.

    본 발명은 압착 펠트층 면에 코팅층을 형성함으로써, 타이어의 회전으로 물이나 이물이 튀더라도 코팅층에서 이를 차단하여 휠하우스 인슐레이션이 파손되지 않고 또한 빗물 등이 휠하우스 인슐레이션에 흡수되지 않게 하여 내구성과 더불어 소음 성능을 개선할 수 있다. 특히, 본 발명은 코팅층의 재질로 LDPE(Low Density Polyethylene)를 사용하므로, 중량 증가를 최소화하면서도 소음 성능과 내구성을 향상할 수 있을 뿐만 아니라 저렴하게 제작하여 안전하게 사용할 수 있다. 또한, 본 발명은 인슐레이션을 휠하우스에 장착했을 때 이러한 코팅층이 타이어와 마주하는 인슐레이션 면에만 구성하므로, 인슐레이션의 전체 중량을 최소화하면서도 주행할 때 타이어에서 튀는 이물과 빗물의 차단 효과를 높일 수 있다.
