Dampers stick on to kill vibration

Sound Dead Steel has introduced a range of self-adhesive steel/aluminium antivibration dampers. They are available as 2000 x 1000, 2500 x 1250 and 3000 x 1500mm or cut to size. The thickness of the material can be specified from 0.5 to 2.0mm (there is no advantage in using more than this). The new dampers avoid fabrication and welding issues. Folding a laminated sound deadened sheet can result in slippage between the two layers of steel. This is avoided by fabricating in the traditional way and bonding the SDS dampers on afterwards. The acoustic benefits are not affected. Welding an acoustic laminate can be tricky as the polymer in a laminate often isolates the two layers of steel. The solution is to fabricate and weld in the traditional way, then apply the SDS damper on the flat areas, missing the welds and folds. SDS is developing a laminate that can be easily welded. Laminates and dampers can be supplied with high a temperature polymer or silicone, which means dampers can be fitted prior to anodising or powder coating.
