The objective of the present invention is to provide a hood insulation for a vehicle which has the excellent noise reduction performance at low costs as the hood insulation is produced by using low-cost resin felt with the low noise reduction performance and high-cost polyurethane with the high noise reduction performance. Especially, the other objective of the present invention is to provide a hood insulation for a vehicle which improves the sound absorption performance through a vent by attaching the resin felt and the polyurethane with PE powder to integrally produce the resin felt and the polyurethane and can improve the sound insulation performance in a part where the vent is not present so as to improve the overall noise reduction performance.

    본 발명은 소음 성능이 낮으나 저렴한 레진 펠트와 비싸나 소음 성능이 우수한 폴리우레탄을 이용하여 후드 인슐레이션을 제작하므로, 저렴하면서도 우수한 소음 성능을 가진 자동차용 후드 인슐레이션을 제공하는 데 그 목적이 있다. 특히, 본 발명은 상기 레진 펠트와 폴리우레탄을 PE파우더로 부착하여 일체로 제작하므로, 통기 구멍을 통해서는 흡음성능을 개선하고, 통기 구멍이 없는 부분에서는 차음 성능을 개선하여 전체적으로 소음 성능을 개선할 수 있게 한 자동차용 후드 인슐레이션을 제공하는 데 다른 목적이 있다.
