Acoustical Products

The primary source of noise intrusion in buildings is through the windows. The proper application of the right windows can mean the difference between performance enhancing serenity and nightmarish distraction. Graham’s acoustically rated fenestration products are made using a variety of styles and framing materials and incorporate differing operating systems to suit nearly any application.

Graham’s acoustic windows and doors meet Sound Transmission Class and Outdoor-Indoor Transmission Class design requirements based upon noise-generated sources.
