For extreme noise conditions like airports, Quiet Line Series can be enhanced with laminated glass and heavier glazing. VT Door Types . Call: (360) 334-4107 Mar 22, 2024 · 3mm thick monolithic glass, glass STC is only 30Dbs,when glass thickness was increased to 12mm thick,glass STC can reach 36Dbs,whether it’s single piece monolithic glass,laminated glass,or insulated glass,the thicker total glass thickness,the better sound transmission loss. To determine the specific STC ratings of glass and a of acoustic glass with high ratings. 52 , 10. 17. • Laminated glass can be drilled, cut and otherwise modified in the shop or field, increasing fabrication Glass meets the requirement of ASTM C 1172 Standard Specification for Laminated Architectural Flat Glass and the safety criteria of CPSC 16 CFR 1201, Category II; and ANSI Z97. STC 30 if you live in an average area but want more privacy, STC 35 is the go to in louder areas, STC 37 if in a louder area and you want a luxury feel or you are pretty close to the airport or overlooking the freeway, STC 40+ is either you live in an area that is obnoxiously loud (seldom the case for single family housing) or you don't want to OA Glass 1 Glass 2 Acoustical Ratings - Ultra I C650 updated 04. -1/4" (total 1/2" thick), 1/4"-0.

Refers to a window manufactured by Soundproof Windows, Inc. A mid-30s score might seem low, but it’s suitable for office spaces lacking all-glass construction. The performance data below applies to an insulating unit constructed with two plies of glass and an air or argon filled space. Laminated glass provides security for both homes and businesses. Heat-strengthened and tempered glass can be incorporated into laminated glass units to further strengthen the impact resistance. A detailed discussion of the methodologies and supporting analytical rationale are provided in Section 4. Therefore, laminated safety glass produced with PVB interlayer provides excel-lent protection against, for example, the effects of vandal-ism, hurricanes or explosions. Kolbe. (cfm / ft 2 of frame @ 1. 5 - 7. Annealed glass can be cut, machined, drilled, edged and polished. Rating. Laminated glass provides higher mechanical resistance and security benefits. . 52 39 20. Performance targets are selected based on acoustic ratings, and results are revealed immediately. Glass size and glazing system will affect STC rating. Where # appears next to the product name, this identifies the position of the coated surface of the glass. fxb jmcfkq iwag amvrb zaadxf ary ibsu tytx mupxi spiu cckbm edx dzdoy vdqpwafg cbphw
