The purpose of the present invention is to provide an insulation for a vehicle, capable of improving noise performance even without changing material or density, shape and the like. In particular, another purpose of the present invention is to provide an insulation for a vehicle, capable of achieving both sound absorbing performance and sound insulating performance no matter which direction noise passes through, by forming a heavy layer that forms a surface layer of a sound absorbing layer to cover both one side and the width and thickness side of the sound absorbing layer when manufacturing the insulation. Also, another purpose of the present invention is to provide an insulation for a vehicle, capable of improving sound insulating performance in a high frequency area even without changing material or density, and shape, by cutting the sound absorbing layer and the surface layer into an insulation form, and then integrally forming the surface layer by covering one side of the sound absorbing layer and the thickness side thereof using a water jet method.

    본 발명은 재질이나 밀도 그리고 형상 등을 변경하지 않으면서도 소음성능을 개선할 수 있게 한 자동차용 인슐레이션을 제공하는 데 그 목적이 있다. 특히, 인슐레이션을 제작할 때 흡음층의 표층을 구성하는 헤비레이어가 이 흡음층의 한쪽 면과 폭 두께 면을 모두 감싸게 구성하므로, 소음이 어느 방향으로 통과하더라도 흡음 성능과 차음성능을 모두 얻을 수 있게 한 자동차용 인슐레이션을 제공하는 데 다른 목적이 있다. 또한, 흡음층과 표층을 인슐레이션 형태로 자른 다음 워터 젯 방식으로 이처럼 표층이 흡음층의 한 면과 그 두께 면을 감싸게 하여 일체로 구성하므로, 재질이나 밀도 그리고 형상을 바꾸지 않으면서도 고주파 영역에서 차음성능을 향상할 수 있게 한 자동차용 인슐레이션을 제공하는 데 또 다른 목적이 있다.
