The THERMATEX® Symetra Rg 4-16/4 x 4, like all tiles in the Symetra range, impresses with its uniform drilled holes and outstanding values in acoustics. It features a so-called block perforation. Uniform breaks in the rows of perforations result in a grid-like pattern of four by four perforations. The result is an accurate, well-ordered surface design ideal for use in show rooms, amongst other applications.
