O Any openings in the barrier (doors, windows, MEP, etc) that have a lower STC rating than the barrier itself, will lower the overall rating of the barrier. Its original intent was to quantify interior building partitions not exterior wall components. The test results are available upon request. Staggered or double stud walls are higher rated than single stud walls. It’s our mission to challenge conventional thinking and create innovative insulation solutions that shape the way we live and build in Cellulose insulated wall: 44 STC Fiberglass insulated wall: 39 STC Uninsulated wall: 35 STC [Cellulose wall rating from the Cellulose In-sulation Mfrs. - All Quanex’s Super Spacer® Standard, featuring polymer EPDM (Ethylene-propylene-diene-monomer) construction, dependably delivers high performance for insulating glass (IG) units, including excellent resistance to ozone, weathering, water and aging, while maintaining its flexibility through wide changes in temperature and barometric pressure. Effective sound insulation appears at STCs around the 50s. B. Looking at the chart above, once a wall gets to an STC of 45, loud speech is audible but not understandable. Knauf acoustical/thermal insulation can improve STC ratings in wood stud construction by 3 to 5 points and metal stud construction by 8 to 10 points depending upon the complexity of the wall configurat STC Ratings Chart Acoustical Performance of Glass and Wall Constructions Overall Thickness Inside Construction Space Outside STC Value ISO The result is sound control over a greater range of frequencies and a significantly higher Sound Transmission Class (STC) rating than a window with standard dual-pane glass. This performance data is not a commitment for Cardinal to produce. This nifty tool helps you determine how effective a building material or structure is at blocking sound. Explore noise reducing windows and doors from Pella. 10). Both STC and OITC ratings inform your window or door selection based on sound insulation Technical Glass Guide Update 6/15/21 – Version 3. 1-7/8" overall - 1/4" glass, 1/2" airspace, 1/4" glass, 1/2" airspace, 3/16" glass, . To determine the specific STC ratings of glass and a Glass Airspace Glass STC OITC 3 mm 6. Overall . STC testing standards are always updated, so an STC rating from two Commonly called acoustic laminated insulated glass, the windows provide an STC of 39 to 54 or greater. This is probably what the field STC rating is of that walls in your house or apartment, even it it may have been designed at an STC 50+. FIRE RATING • Fiberglass insulation is inherently non-combustible because it is made from mostly sand and recycled glass • The tables show STC ratings of the same wall assemblies with either fiberglass or rockwool filling the cavity. Middle Glass . STC Value of Equal Thickness of Mineral Fibers (35⁄8" [92 mm] Steel Studs; Single Layer 1⁄2" [13 mm] Gypsum Board STC 50 / OITC 35 R-13 Faced 202-96 Insulation Over the Girts 3 5/8” Steel Studs on 24” Centers with 1/2” Gyp. 1 mm) 1/4" laminate 1/2", Air 1/4" 39 39 STC is determined by a weighted average of TL values taken over 16 frequencies, which are fitted to a curve in a method defined by the ASTM E413 Classification Standard for Rating Sound Insulation. Special coatings to create low emissivity (“low-E”) glass. STC 43* 15/ 8" (41 mm) steel studs: single layer 5/ 8" (16 mm) Type X gypsum board each side; one thickness 23/ 4" (70 mm) JM Formaldehyde-free thermal/acoustical fiber glass batts. There are many different opinions on what constitutes a ‘good’ vs ‘very good’ rating, as the definitions are up for personal interpretation. Most of the time, an assembly’s OITC rating is lower than an STC rating. *OITC is estimated based on this test. The glass types listed below are included in the Laminated Glass offering. The newest generation of VacuMax™ VIG is now manufactured exclusively with Solarban ® 70 solar The answer to a noise concern is not less glass, but the use of innovative laminated safety glass made with Saflex™ Acoustic PVB interlayer. On the Oct 5, 2024 · Glass size and glazing system will affect STC rating. 5. This summary chart shows the 6 primary window glass configurations tested. The STC is a standardized rating provided by ASTM E413 based on laboratory measurements performed in accordance with ASRM E90. While adding remedies to the space will prevent excessive noise levels from rising, Laminating glass is a popular way to increase an STC rating.

Having stated that, the use of any fiberglass insulation can increase the partition assembly STC rating 4-10 points and we have isles full of product that will accomplish a higher rating. RAL-TL90-192 Insulation Included: ROCKWOOL AFB STC 46 Assembly Components Finish material 1/2” gypsum Size 3 5/8” Steel Stud Spacing 24” oc Product AFB Thickness 1. The U. Sound Transmission Ratings Nt Window Glass size and glazing system will affect STC rating. The STC (Sound Transmission Class) is a rating system for interior building partitions and viewing windows used to The OITC (Outside-Inside Transmlssion Class) rating is used to classify acoustic performance of glazing in exterior Triple Insulating Glass Construction STC OITC 100 125 160 00 2 250 315 400 500 STC Ratings Explained – A Powerful Guide to Quieter Spaces STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. The STC provides a standardized way to compare products such as doors and windows made by competing manufacturers. Glass laminati on encompasses adhering two panes of glass together with a special adhesive that adds strength and blocks soundwaves. Heat efficiency usually requires a maximum gap of 16 millimeters, but a larger space is always better for soundproofing. Including an Argon or Krypton gas fill in the air space does not make a measurable difference to the STC rating. Click here to review the full details.
