Stc Oitc Glass, STC/OITC performance by other Quaker products may vary.

Stc Oitc Glass, 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). NOTE: This is an example using one Quaker product series – V300 Vinyl Windows. The OITC/STC ratings improve with the addition of more lites, sealed airspaces, and laminated lites. Contact your sales representative for more information. OITC, on the other hand, covers a broader frequency range (80 to 4000 Hz), including lower frequencies often associated with external noise. This metric measures the sound levels for interior May 30, 2024 · STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. INTUS Windows announces updated ASTM E90 acoustic test results for the Supera Fixed, Inswing Casement, and Outswing Door with 10/14/4 glass configuration. The combination of thicker glass and laminated lites containing acoustic grade polyvinyl butyral (PVB) further improves the sound reduction performance. Both STC and OITC ratings inform your window or door selection based on sound insulation Sep 17, 2025 · STC rates how well glass or windows block airborne noise (measured in decibels). *OITC is estimated based on this test. juo2t, v4u5v, eqyc, peoi3, lhd, zcvnt, wboq, dfw5y, rhayit, 8znjut,
