Abstract
A roof construction has vibration dampening ability and includes a body member in contact with a waffle-like surface of a moulded porous compressed fibrous web which is designed to have a self-supporting stability. The waffle-like surface exhibits an anisotropic air resistant structure.
Claims14
A vibration-damping roof construction comprising:
- at least one body member having an interior surface and an exterior surface;
- and
- a sound-absorbing moulded part made of a porous, compressed fibrous web material and having a side facing said interior surface of said body member, said moulded part having locally stiffened regions giving said moulded part a self-supporting stability, and said side facing said body member having a waffle-like structured surface of spaced depressed surfaces separated by individual projecting segments arranged in a grid of spaced horizontal and perpendicular lines, said segments resting in contact with said body member, and said structured surface exhibiting an anisotropic air resistance.
A vibration-damping roof construction comprising:
- at least one body member having an interior surface and an exterior surface;
- a sound-absorbing moulded part made of a porous, compressed fibrous web material and having a side facing said interior surface of said body member, said side facing said body member having a waffle-like structured surface of spaced depressed surfaces separated by individual projecting segments arranged in a grid of spaced horizontal and perpendicular lines, said segments resting in contact with said body member, and said structured surface exhibiting an anisotropic air resistance;
- and
- a load-bearing stiffening layer embedded in said moulded part, said stiffening layer giving said moulded part a self-supporting stability.
A sound-absorbing lining suitable for use in the interior of a vibration-damping roof construction, said lining comprising:
- a moulded part comprising a porous, compressed fibrous web material, said moulded part having locally stiffened regions giving said moulded part a self-supporting stability, and said moulded part having a side having a waffle-like structured surface of spaced depressed surfaces separated by individual projecting segments arranged in a grid of spaced horizontal and perpendicular lines, said structured surface being configured to impede air currents less in the lateral direction than the air flows at a right angle to the lateral direction.
