Sound insulation Fence/ Noise Barrier,perforated moise barrier
We manufactures and installs different types of screens against
noise pollution coming from linear infrastructures (roads and
Metal screensare 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
The reflective face leaves a space with rockwool creating an
acoustic chamber, so that the sound waves reflect on it into the
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
