When forming a sound insulator, the part surrounding the bonding unit is unfolded, and polyurethane is used for foaming molding. Then, the folded line is formed to be folded as it was originally. Accordingly, the polyurethane foaming molding is sufficiently conducted to an inner surface of the part surrounding the bonding unit, and noise performance can be improved. More specifically, the part with the folding line can be made as a weak part which is thinner than other parts, or one or more slits can be formed on the folded part. Accordingly, dash insulation can be easily folded along the folding line, and come in close contact with the dash panel surface, and noise performance can be improved. In addition, an upper panel bonding part of the cowl box can be foldable through a connection part, and dash insulation can be folded at once to be easily and conveniently mounted along the bonding part formed to come in contact with the dash insulation.

    차음재를 성형할 때 접합부를 감싸는 부분이 펼쳐지게 하고, 폴리우레탄을 발포 성형한 다음 접힘 선을 형성하여 원래대로 접을 수 있게 구성함으로써, 접합부를 감싸는 부분의 안쪽 면까지 폴리우레탄 발포 성형이 충분히 이루어지게 하여 소음 성능을 개선할 수 있다. 특히, 접힘선으로 다른 부분보다 얇게 형성하는 연약 부분으로 형성하거나, 접히는 부분에 적어도 하나의 슬릿을 형성함으로써, 접힘선을 기준으로 대시 인슐레이션이 쉽게 접히면서 대시 패널 면에 맞게 밀착하게 하여 소음 성능을 개선할 수 있다. 또한, 카울 박스의 상부 패널 접합 부분에 연결 부분을 통해 접을 수 있게 구성함으로써, 대시 인슐레이션에 전체적으로 접하게 형성되는 접합 부분을 따라 대시 인슐레이션을 한 번에 접어서 쉽고 편리하게 장착할 수 있다.
