The pantallas acústicas developed by INSAMETAL S.A., They are aimed to eliminate noise pollution coming in most cases of linear infrastructures, road and rail. INSAMETAL panels S.A. They consist of modular panels aluminum Osteel according to the model, Profiled and termolacados. Normally, one of the sheets with perforations (absorbent face), and other smooth (reflective side). We also manufacture doubly acoustic panels with both perforated sides when absorption is needed on both sides of the vial. The plates are connected by a specially designed housing for our R + D + I high quality polypropylene, which prevents vibration in the case of extreme gusts produced by the passage of trains Ave.
Inside the acoustic panel consists of sound-absorbing material, rockwool usually high density in different densities and thicknesses. INSAMETAL S.A. dispose of various models of acoustic panels to adapt to the particular needs of each project. The panels overlap horizontally between uprights galvanized steel, the raw materials used in the manufacture of our panels are always top quality.
