Sound insulation Fence/ Noise Barrier
We manufactures and installs different types of screens against noise pollution coming from linear infrastructures (roads and railways).
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 HEA / HEB steel profiles.
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.
Rockwool achieves a reduction in noise level due to its fibrous and elastic nature, which dissipates the energy of sound waves that penetrate them.
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 HEA / HEB 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.
