ECOTONE™ (SW-1) Anechoic Wedges: – Extremely low-density material and this facilitates installation, as wedges can adhere directly to the anechoic chamber walls and roof with the minimum of mechanical fixings, there is no air gap. Length of wedges will depend upon Cutoff Hz, Very light, easy to install (glue), exhibits superior fire, off white color, easily replaceable.ECOTONE™ (FL) Fabric-covered wedges:- Wedges will be fixed onto perforated sheet metal angle brackets (just like mineral wool wedges) This makes removal of the wedges easier at a later date if required as the wedges are not glued. Wedge covered with non-flammable glass-fiber fabric. The cover does not absorb dirt that easily and can be replaced at low costs, resistant against contact damage, air gap at the back improves acoustic performance.
