Betta Absorptive Acoustic Barrier With Timber Finish To Both Faces.
A 3.0 metre high Betta Absorptive Barrier with timber finishes on both sides and blends well with landscape features in commercial, and industrial settings.
The absorptive face consists of a black breathable membrane, 25 x 25 black weldmesh and 17 vertical chamfered timber trims per 2.4 metre bay.
A five vertical trim finish is a more economical option where blending with the environment is not so crucial and a tough industrial face can be offered with heavy galvanised weldmesh.
The barriers universal posts may be galvanised, galvanised and powder coated or timber clad. The standard pressure treatment for the timber is Tanalith E with green or brown tints.
In sensitive residential areas, where planning / conservation constraints are strict, the absorptive face may be finished with willow / hazel woven hurdles or thin vertical feather edged pales. This type of finish reduces the absorptive performance of the barrier slightly but there is a slight gain in the airborne insulation.
The standard Betta Absorptive Acoustic Barrier, during laboratory tests, was given a sound insulation rate of 26 dB and classified as category B3 in accordance with BS EN 1793-2:1998 and 20 dB sound absorption, category A4, in accordance with BS EN 1793-1:1998.
It should be noted the Betta Group can design and install any height of Barrier to meet a client's need.
