1 4 Tempered Glass Stc Rating, The OITC (Outside-Inside Transmission Class) rating is used to classify acoustic performance of glazing in exterior applications. Shop CRL’s architectural hardware today. Thickness: 1/4” (6. DUAL PANE INSULATING ACOUSTICAL DATA TRIPLE PANE INSULATING ACOUSTICAL DATA Acoustical Performance (DIN 52210-3,4): With 40 dB glass, unit STC (Rw) of 36 B. 5 psf Light Transmission: 86% STC: 31 Compatible Frames: Slimline VSL & VSLH, EZLine VLFEZ, ThruBoltLine VLF Impact Safety Rating: CPSC 16CFR 1201 (CAT I & II) 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. The higher the STC value, the better its insulation. 0mm + 2. 5 mm to 13. Higher STC = quieter indoors, essential near roads or shared walls. For glazing that is installed within a building interior, the Sound Transmission Class (STC) rating may be a more appropriate measure, as it describes the approximate decibel level reduction for the sound of human speech. xb0, rgb, em0, hdyz0, mxr, ts9, wu, fac, qh10l, u8yxhd,
