What is an Acoustical Window?
Windows are designed into structures to provide viewing, to transfer light and outside air, and for aesthetic value. When a window must also provide significant acoustical isolation, the design, construction and installation of window assemblies must be carefully controlled for a successful result. Glass panes (and typical residential and commercial windows) are not inherently good acoustical barriers. Such windows provide various levels of acoustical isolation (STC ratings) depending on the specific construction of the assembly. When “typical” assemblies do not provide adequate isolation, acoustical windows can be considered. Acoustical windows are typical windows that have been acoustically upgraded by increasing the thickness (weight) and number of glass panels, the air space between the glass, improving the glazing system for the glass, and improving the sealing system between the glass frame, window frame and structure. STC and Coincidence Dip Acoustical windows come in various co
