1 4 Tempered Glass Stc Rating, STC ratings commonly range between 30 to 75+ and are largely dependant on the type of materials used in the assembly and the care taken in construction. Sound Transmission Basics Single Glazed A single pane of glass has an STC rating ranging from the high-20s to the mid-30s, with its score rising as the glass gets thicker. Impact Safety Rating: CPSC 16CFR 1201 (CAT I & II) Shop Teza Doors & Windows 120 Series 23-1/2-in x 23-1/2-in Center-operable Black with Black Interior Aluminum Sliding Window With Tempered Glass (Full Screen Included) in the Sliding Windows department at Lowe's. Impact safety-rated: complies with IBC requirements for use in doors. LAMINATED ACOUS ICAL DATA INSULATING LAMINATED ACOUSTICAL DATA DOUBLE LAMINATED INSULATING ACOUSTICAL DATA Double Laminated Insulating Glass The OITC (Outside-Inside Transmission Class) rating is used to classify acoustic performance of glazing in exterior applications. com. Laminated Glass Specifications Laminated architectural glass is produced by bonding a polyvinyl butyral (PVB) interlayer between two or more lites of glass under heat and pressure. Tested under ASTM E90, panels caulked in place with wooden stops and glazing putty. Teza's Multi-sliding windows provide any space with a contemporary style. Light Transmission: 86% STC: 31. 1 Class A and CPSC 16CFR 1201 (CAT I and II) 1" thick - consists of two pieces of 1/4" thick clear tempered glass with 1/2" air space between and butyl seal An STC rating of 30 or below is typical for standard hollow doors and offers minimal sound isolation. For example, while a single 1/4-inch piece of glass achieves an STC rating of 31, doubling up with two 1/4-inch pieces does not double the rating to 62; instead, it only increases to 36 STC. The result makes laminated architectural glass an excellent choice for safety glazing. See additional notes below data for specific details. 0 mm and increasing the glass thickness of both lites from 3. Laminated glass is designed to crack upon impact but tend to remain in its opening, reducing the risk of injury or property damage. Acoustical Performance Results For example, increasing the airspace from 6. 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. 1 Class A and CPSC 16CFR 1201 (CAT I and II) 1” thick - consists of two pieces of 1/4” thick clear tempered glass with 1/2” air space between and butyl seal VT STC approvals include tempered, ceramic (laminated and filmed), wired, and insulated Metal Vision Panels and woodstops approvals available See VTsoundsource, our acoustical navigator, for glass size/thickness, Metal Vision Panel, and woodstop approval Product Specifications Material: Heat-treated clear safety glass that breaks into small particles. Insulated Tempered Glass Impact safety-rated: complies with IBC requirements for use in doors. Thickness: 1/4” (6. 0 mm results in an approximate STC rating of 34 (28 + 2 + 4 = 34). 5 psf. 4 mm) Weight: 2. STC calculations meets standards of ASTM E413, and ISO 717-1. Meets ANSI Z97. 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) Sound Rating Up to Unit STC 34 NanaWall SL45 has been tested at an accredited and certified independent laboratory. For reference, standard house walls are 33 STC, while studio-level soundproofing requires a rating of at least 45. . Two pieces of 3/16″ thick clear tempered glass. The STC rating system looks at the amount of noise mitigation provided by the assembly over a broad range of frequencies and a single number is calculated as its rating. For a noticeable reduction in street noise and conversation, look for doors in the 35 to 40 range. Its original intent was to quantify interior building partitions not exterior wall components. As a result it is not recommended for glass selection of exterior wall applications since the single-number rating was achieved Insulated Tempered Glass Impact safety-rated: complies with IBC requirements for use in doors. DUAL PANE INSULATING ACOUSTICAL DATA TRIPLE PANE INSULATING ACOUSTICAL DATA 1-inch insulated impact and safety-rated glazing for commercial door vision lite frames. 1 Class A and CPSC 16CFR 1201 (CAT I and II) 11" minimum height.
