Acoustical Subsurface & Acoustical Fiberglass
ACOUSTICAL SUBSURFACE
Accutrack Panels, Baffles and Upholstered Wall Systems utilize molded fiberglass boards as a subsurface for all acoustical applications.
Acoustical board is a thermal and acoustical insulation product made from inorganic glass fibers pre-formed into boards bonded by a thermosetting resin. The board is manufactured with a smooth surface on one side and is precision cut with a 1/16" tolerance in thickness, insuring perfect alignment within the Accutrack framework.
