An improved silencer panel construction for use in the exhaust gas stream of power generation equipment is described. The silencer panel has an outer periphery of U-shaped channel. Perforated webbing is attached within the outer periphery to strengthen the outer periphery and reduce thermal gradients building up within the web during operation. Acoustical insulation is provided within the silencer panel and held in place by screening as well as perforated cladding. A plurality of silencer panels are spaced apart within the silencer chamber to attenuate the noise produced by the exhaust gas stream.
