Modular steel noise barrier system. Highly efficient, Absorption Class A, Rw 32dB, acoustic modular acoustic panel for acoustic enclosure and acoustic barrier constructions for both internal and external applications.
AC80 is an Industrial Noise Barrier panels acoustic screens solution in a modular format. With this noise barrier system there is no need for expensive bespoke manufacture. Noise Enclosures or acoustic barriers and screens can be constructed on-site using the modular steel sections which are easy to configure.
A supporting frame is almost always required. The supporting framework needs to be able to accommodate any significant wind loadings that may be experienced. The distance between the supporting steels will depend on height and other factors but is usually no less than 1800mm centres and no more than 3000mm centres.
| Feature | Modular Steel Barriers | Concrete Sound Walls | Traditional Fencing |
| Primary Mechanism | Sound absorption and noise blocking | Highly sound reflective | Minimal sound blocking |
| Installation Speed | Fast (prefabricated panels) | Slow | Fast |
| Weight Load | Lightweight structure | Extremely heavy footprint and cost | Light |
| Maintenance | Low | High (structural cracking) | Frequent Repair |
The panels are T&G so slot together using the proprietary trims.
The perforation percentage for the face of these panels is 28%. Each panel has five different kinds of perforations diameter. The perforated side of the panels should face the noise source.
Non perforated corner units can be used for both internal and external corners.
If these panels are being used for an internal acoustic enclosure then the 1.2mm thick profiles are generally adequate. However for external application, and especially for welding, the thicker 2.5mm PF80/01 and Omega profiles should be used as the thin profiles cannot accept welds.
For machine noise enclosures the following are available:
Generally, small machine noise enclosures do not require any additional support framework but for external use as noise barriers (or large enclosures) then an internal or external support structure will be required. This may need to take into account wind loadings and/or silencer weights (if roof mounted) so it is best to consult with a structural engineer on these matters. Often support braces are required every 2-3m or so.
Made of 1.2mm pre-lacquered galvanised smooth sheet metal shaped to be assembled with the panels. The omega and PF80/01 trims are available in a 2.5mm thickness which can be welded to the support structure.
The PF80/01 ‘U’ channels are fixed to the base, the main panels slot into this profile. The same PF80/01 can be used to cap off ends or the top. The Omega profile acts as a central ‘brace’ which. at 2.5mm can be welded to. Self drilling facade screws can be used for installation.
