Noise Barriers - Galvanized Steel With Rockwool Core | Multi-perforated Absorbing Face, Reflective Acoustic Chamber

HSE manufactures and installs different types of Noise Barriers.
Metal screens are made of galvanized steel panels that make up a sound-proof casing inside them. The panels overlap vertically between studs made from steel profiles.

CONSTITUENTS:



ABSORBENT FACE oriented to the focus of noise:
The absorbing face is a multi-perforated metallic element. The design of the perforations allow to the sound wave to enter in the panel and being dissipated into the absorbent material.

SOUND INSULATION:
Rockwool achieves a reduction in noise level due to its fibrous and elastic nature, which dissipates the energy of sound waves that penetrate them.

REFLECTIVE FACE:
The reflective face leaves a space with rockwool creating an acoustic chamber, so that the sound waves reflect on it into the absorbent material.

Supporting structure: consists of MS Steel beams hot dip galvanized and painted with polyester powder paint.

The profiles are conveniently sized and arranged with a distance inter-axis depending on structural requirements.

The beams are placed in holes already made in the concrete or they have a base plate anchored to the foundation by galvanized steel screws.
