Sound-absorbing and sound-insulating metal panels CIR HBS™ composed by:
posterior full half-shell sheet in steel, galvanized according to Sendzimir process UNI EN 10346:2009 (minimum thickness of the zinc coating Z200 gr/m2), and painted with polyester powder; different RAL colours and special finishing can be chosen; as alternative this half-shell sheet could be produced in self-passivating CORTEN steel
Sound-absorbent blanket in rock wool covered by a glass fibre veil or as alternative sound-absorbent blanket in polyester
anterior perforated half-shell sheet, faced to the source, composed by perforated or expanding sheet in aluminium or steel, various RAL colours, special finishing
ends are closed off with patented plastic heads in polypropylene, resistant to UV, ozone, hot-cold cycles
In reference to the CIR HBS system, It is possible to install sound-insulating transparent panels composed of:
– perimeter frame in galvanized and painted steel or as alternative in self-passivating Corten steel; the frame can be painted in all RAL chart colours
– transparent, colourless or coloured PMMA (polymethylmethacrylate) or tempered, laminated glass sheets
– accessories and screws to fix transparent sheets
height: 500 mm
length: fino a 6.000 mm
thickness: 100 mm / 140 mm
Sound absorption: class A4 (maximum) according to UNI EN 1793-1-
Sound-insulation: class B3 (maximum) according to UNI EN 1793-2
The panel type CIR HBS was developed to improve some aspects of the “classic” noise barrier.
Continuous surface on side faced to the source (street side), without interruption and hidden columns; thanks to the HBS™ hook system it is possible to install panels outside of the support structure as well as between the HE-profiles (standard installation);
Light lattice steel structure: thanks to the HBS™ hook system it is possible to use different supporting structures like the lattice steel structure called CIR LTXTM;
TECHNICAL AND STRUCTURAL ASPECTS:
High mechanical strength: thanks to the high load resistance of the HBS™ panel, post-distances up to 6.00 m are possible (with load resistance up to 180 kg/m2, for loads up to 250 kg/m2 the post-distance must be reduced)
Adaptable to different support structures (lattice steel structure or between HE-profiles)
Quick installation – time reduction: thanks to the possibility to reach post-distance up to 6,00 m the duration of the site is significantly reduced
Reduction of foundation costs: thanks to the possibility to reach post-distance up to 6,00 m
