Stc Oitc Glass, Data is based on testing ~36" x 84" glass to ASTM E413-87 in an acoustical wall.

Stc Oitc Glass, NOTE: This is an example using one Quaker product series – V300 Vinyl Windows. In The definitions of two ratings: Sound Transmission Class or STC and Outdoor-Indoor Transmission Class or OITC The project’s design requirements and how they impact the glazing system, and How to calculate an STC or OITC rating STC versus OITC The first measure of acoustic performance is referred to as the Sound Transmission Class or STC. Sound transmission class (STC) and Outdoor/Indoor Transmission Class (OITC) are measured in decibels (dB) and are the standard method for rating sound attenuation characteristics of glass products and window The performance data below applies to triple insulating glass units constructed with three plies of glass, two airspaces and an interlayer (where applicable). OITC, on the other hand, covers a broader frequency range (80 to 4000 Hz), including lower frequencies often associated with external noise. STC/OITC performance by other Quaker products may vary.
