The Sound Transmission Class (STC) is a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. Insulating gas Any of these factors, alone or in combination, can have an impact on the STC rating and performance of your window or door. But what does that really mean? A sound transmission class chart is a simple way to understand the decibel scale and its relation to STC ratings. Where to insulate for acoustic control. Sound transmission class (STC) ratings solve that problem by giving a single value to acoustical performance for a door. 39 . 030" P. DOUBLE LAMINATED INSULATING ACOUSTICAL DATA. k. Gypsum Wallboard (each side) Finish Insulation STC Fire Rating . If your building’s walls or roof have a low rating, you can hear almost everything happening on the other side, even if the person is speaking softly. Determine Target IICs. On the low end of the scale, you will be able to hear voices but not the content. Sound transmission reduction wall designs are given for both single stud and staggered double stud structural and partition walls. IIC stands for Impact Insulation Class. "The Facts About the Acoustical Performance of Metal E413-87 in an acoustica l wall. This rating is based on the requirements that the value of transmission loss at any of the eleven measuring frequencies does not fall below a specified TL-frequency contour. Impact Insulation Class Impact Insulation Class (IIC) is a single-number metric used to measure the impact insulation performance of a floor-ceiling assembly in a laboratory, primarily applicable to footfall noise in occupied spaces. Ecolife Solutions online insulation shop makes choosing and buying insulation online easy; we'll even deliver right to your door in Sydney, Brisbane, Canberra and beyond!. When tested in the field, an STC rating of a wall assembly will almost always be lower than the lab Recommended STC Ratings on Corridor & Demising Walls. 1 hr. STC Ratings & Steel Stud Framed Walls . 3 use 50 as the minimum STC rating for airborne and structural sound in multifamily homes. 5/8” type X, one layer . Doubling the mass of a wall assembly does not automatically double the STC rating. 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+. A sound reduction of 35 decibels is very high. An increase from 30 to 40 means 90% of the noise is reduced. Achieve greener insulation solutions today! Skip to content. A higher number indicates more effective sound insulation than a lower number. Often times, specialty insulations do not perform any better than standard batt insulation. com. Key areas for insulation Insulation. , Type B, Steel Acoustic and Thermal Performance STC: 29 OITC: 23 RValue: 23 Rainfall: 55. That means that if we were to use 4-inch fiberglass batts, the overall R-value would be R-14. There are other factors to consider. 8. STC is highly dependant on the construction of the partition. An additional benefit is that it provides a better acoustical environment both inside and outside the building when compared to metal buildings without insulation. 33; The STC rating is not indicative of the number of decibels (dB) that will be reduced but represents a means of specifying materials for acoustical wall assemblies that will provide the required noise reduction (i. (Fire Rating) UL Number USG Levelrock® Sound Mat USG Levelrock® USG Durock™ Underlayment (a) Insulation Framing Member Depth RC Deluxe® USG Sheetrock® Brand Firecode® C or X Gypsum Panels Floor Covering Sound Rating Test Number STC IIC Engineered Wood I-Joist (1 Hour) L570 L589 M502 M506 SAM-N12™ 1/8 in . e. Sound Transmission Loss (dB) 43 1-3/8" overall - 1/4" glass, 3/4" airspace, 3/8" glass. Implementation of the appropriate rating system is important because OITC and STC ratings are not linearly related, and the achievement of a strong STC rating does not necessarily correlate with a similar OITC rating. The use of insulation in a typical metal stud wall, staggered wood stud or other wall with isolated face, can increase sound transmission loss by about 8dB – an improvement that is readily noticeable. However, when building hotels, the STC of 55 for demising walls and STC 50 for corridor walls isn’t a building code requirement – this is what we call a “brand Denser materials have better STC ratings. Acoustical Assemblies STC Rating Reference Guide. As previously explained, this means they have been tested in a laboratory for their sound transmission loss. Transmission The passage of sound waves from its source, through a vibrating medium, and to a listener. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. Of course, the higher the STC rating, the better. Building Material: R-Value (1 Inch Thickness) R-Value (5 Inches Thickness) R-Value (10 Inches Thickness) Closed Cell lower than STC ratings for the same assembly, due to construction variations in the field. Address: 6301 N Florida Ave Tampa, FL 33604 The STC rating for a basic insulated 2×4 wall with a single layer of drywall on each side is 35-38. After sealed IG units were installed into the laboratory test opening, the first glass panel and wood spacers were used to complete the triple glass configurations. (STC) requirements. How It Works: Airborne noise travels through air gaps and weak points in walls and floors. Is Complete Soundproofing Possible? Our STC rating chart above only goes to 50 because STC rated windows are in that range. Fiberglass R-13 Unfaced. C. Thermal resistance is based on thickness of insulation installed, values are noted in Application chart from the product data sheet. The shape of this contour is drawn to represent Canada's No. jm. A good level of isolation for walls and ceilings is STC 50 plus. The STC rating Maximum noise insulation is achieved by laminating one Hot Water Heater Insulation: Insulate water heaters to prevent costly energy loss. The STC rating goes all the way up to 65. A higher sound transmission class rating indicates more effective sound insulation than a lower rating. STC ratings are the Phone: 888-815-9691. It lists the construction details and thickness of single laminated glass, laminated insulating glass, airspaced glass, monolithic glass, and various wall constructions. As a rule of thumb, doubling the mass generally improves sound insulation by about 5dB. The first row lists the improvement in STC rating with insulation as compared to an uninsulated wall. 1 † Insulation. Acoustic Insulation are classified as NON-COMBUSTIBLE in compliance to the Canadian Standard CAN ULC S114 Recycled Content, Efficient Manufacturing & Product Benefits The tables below show STC ratings of the same wall assemblies with either fiber glass or rockwool filling the cavity.
