A wall system with an STC < 35 is considered low performance, whereas one with an STC > 55 is considered high performance. It is determined in accordance with ASTM E413 using sound transmission loss data measured between 100 – 5000 Hz. Tempered glass is one kind of safe glass being produced by the heating flat glass to its softening point. Insulation will noticeably improve the STC rating of an assembly. ” When evaluating STC ratings for partitions, it’s crucial to consider key factors that influence sound insulation effectiveness. concrete, glass, steel) using graphical computation method based on the material thickness, density, and critical frequency values. Standard ½” glass (clear tempered) STC 34: Standard 3/8” glass (clear tempered) So go ahead, turn it up (and feel free to OITC and STC are almost the same rating system except that OITC is geared for testing lower frequencies. 4. STC ratings are used for windows, doors, walls and most building materials. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. However, because of the break pattern, tempered glass is much more likely to evacuate the glazing system immediately upon breakage. Finishes Front, center, back or multi-plane glass applications; Flush glazed from either the inside or outside; Screw spline, shear block, stick or type-B fabrication Acoustical rating per AAMA 1801 and ASTM E 1425; Project specific U-factors (see Thermal Charts in Architectural Detail Manual) Data is based on testing ~36″ x 84″ glass to ASTM E413-87 in an acoustical wall. Glass size and glazing system will affect STC rating. The STC ratings for windows and glass can range from 18 to 65, depending on the type and thickness of the glass.

Ensure you understand the testing methodology, installation quality, and the role of sound absorption The average STC rating for a regular single pane window is 27. This is because the multiple layers deform the sound waves in different ways, muffling the sound even further than a monolithic piece of glass. IQ: Insulating Glass. Glass and Solar Energy; Green Resources; Our Solar Commitment; Sound insulation rating of the window system/glazing and; 3. The STC rating is a single-number rating Glass Product Type and Thickness STC Rating OITC Rating; ¼" Monolithic Glass: 31: 29: ½" Monolithic Glass: 36: 33: Calculate Correctly. while solid wood/solid core doors and MDF doors offer better soundproofing with STC ratings from 30 to 50. For more sound dampening Phone: 888-815-9691. 52mm, is a kind of laminated glass. Glass offers a healthy option for flexible space, transparency, versatility, efficiency, and a low cost of ownership. Compare the Among the numerous glass options available, annealed glass and tempered glass have emerged as two of the sought-after choices. The performance of the final BTG 13. For reference, standard house walls are 33 STC, while studio-level soundproofing Muraflex STC rating 3/8" Tempered Glass – 1” air space – 1/2" Laminated Glass .

Multiple configurations can be added to the list by clicking "Calculate – Compare Additional Products" after building the next configuration. 1 mm) 1/4" laminate 1/2", Air 1/4" 39 39 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. the data applies to double-pane insulating glass units using tempered double-strength glass and laminated double-strength glass with a 9∕16″ airspace. 3/8" Tempered Glass – 2” air Acoustic Calculator. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing Two Panes of tempered glass with a metal spacer in a sealed insulated glass unit – Each Pane: 3/16″ Approx. Table 1A provides a guide to examples of noise measured in decibels TABLE 1B: GLASS SOUND REDUCTION RATINGS Rw (dB) Page 3/3 situations, the Rw does not account for all noises generated. All performance data is calculated using LBNL Window 7. If thicker glass material is used, the rating can go up to 35. -1/4″ AS(2)-1/8″ For monolithic, laminated or insulating glass unit performance data, please go to SystemSelect ™, our on-line glass performance calculator. Custom IG unit designs can be fabricated with glass thicknesses ranging from 1/8″ to 3/4″ and with airspace thicknesses ranging from 3/16″ to 7/8″ having standard spacer colors of clear, bronze and black anodized, and mill finish aluminum.

We would like to show you a description here but the site won’t allow us. 49; Egofine Heat-Strengthened Glass Replacement for Picture Frame: $16. 52mm laminated glass is 39. The performance values shown above represent nominal values for the center of glass with no spacer system or framing. Sound Transmission Class (STC) is a measure for rating the performance of a wall system as a barrier to airborne sound transmission between adjacent closed spaces such as offices. STC ratings are calculated by a weighted average of Transmission Loss (TL: a door’s ability to reduce noise) values taken over 16 frequencies, which are fitted to a curve in a method defined by the ASTM E413 Classification Standard for Rating For your typical interior office tempered glass wall partitions, you can expect an STC of about 32. 3/8" Tempered Glass – 2” air 10 Glass Fittings for Interior Swing Doors 12 Architectural Pulls, Handles, and Locksets 14 Concealed Closers, Pivots, and Glass Panic Hardware Contents dormakaba interior glass systems bring the benefits of glass to your projects. For doors, the STC rating is critical because it determines how well the door blocks sound from passing through. The Energy Savings view provides savings as overall percentages based on a 15% window-to-wall ratio and comparing the selected insulating glass configurations to 2 pane clear glass insulating glass units. 38 - 40. Once a calculation is complete, users have the option to refine these selections, and then receive a detailed report including acoustic ratings, test details, a sound transmission float glass (also called “flat” glass) that has not been heat-strengthened or tempered is annealed glass.
