PERFORMANCE
/ / STC/OITC ratings are measurements used to gauge how well window and door products provide noise reduction. Windows and doors can be used as a sound barrier for outside or inside noise. The higher the rating, the better the sound control. Factors such as glass type, glass thickness, and airspace between the glass should be considered, as all affect STC/OITC ratings. A wide selection of Forgent Series products can be upgraded to meet specific needs.
