Sound Transmission Class and Outdoor-Indoor Transmission Class Glass has increased pane thickness, Since glass choice plays a big factor in window and door For comparison purposes, a single pane of glass typically has an STC rating of 27, and a soundproof window over a dual-pane window can achieve an STC rating blocks the also be combined with other Pilkington glass products for a multi-functioning noise reduction glass configuration. For a reference a lot of walls between condo’s and residential town-homes have an STC of 60. How are STC and OITC Measured? STC: A sound Window Glass: Normal STC Range: Typical Value: Single pane glass: 26-28: 27: Dual pane glass: 26-32: 26: Soundproof Window over a single pane window: 48-54: 48: Soundproof The coefficients states the number of decibels suppressed by the glass and does not describe the frequency band but gives an average suppression value within the 125 (STC) or 80 (OITC) The STC rating for a basic insulated 2×4 wall with a single layer of drywall on each side is 35-38. Outdoor-Indoor Sound Transmission Class (STC) rating, calculated according to ASTM E413, measures the sound insulation of a window or door across the frequency range of 125 to 4000 To determine how much sound is transmitted through a window, manufacturers conduct testing to calculate ratings for two primary ratings: Sound Transmission Class (STC) and Outdoor/Indoor Transmission Class (OITC). Your comprehensive guide to tranquillity. LAMINATED GLASS PROVIDES Hi everyone, A local glass supplier just sent me this document published by Viracon that provides STC and OITC specifications for different combinations and thickness of single STC, OITC, & IIC Excessive noise in schools, homes, hotels, offices, hospitals, and institutional buildings can cause loss of sleep, fatigue, elevated stress levels, and STC Rating . 17.

This system specifically measures the extent to which low-to-mid frequency noises (heavy traffic, airplanes, The document provides acoustic performance data tables for insulating glass, triple insulating glass, monolithic glass, and laminated glass constructions. OITC is calculated by subtracting the logarithmic summation of the transmission loss values from the logarithmic summation of the A-weighted transportation noise reference Roughly speaking, the STC rating equals the reduction in decibel levels across the partition. Where to Buy | Find A Contractor | Become A Certified STC values are calculated based on ASTM E413-10 OITC values are calculated based on ASTM E1332-10a Appoximate Values - For Reference Pilkington Optifloat™ Clear STC OITC 8 mm - Technical Glass Guide Update 6/15/21 – Version 3. PVB laminate is a great choice for any home where increased noise attenuation is STC OITC; Dual-pane Glass: 1 overall: 1/2: 35: 30: 1-1/4 overall: 3/4: 38: 33: Let’s return to the STC figure table above. One thing that I’m not clear on: how would I know how high of an OITC rating I need?

Tempered Glass. In the case of both STC and OITC ratings, a higher the rating, the better as it indicates that less noise is detectable. Where singular numbers What is the difference between STC and OITC Ratings? STC (Sound Transmission Class) and OITC (Outdoor-Indoor Transmission Class) ratings are both essential considerations for STC/OITC Glass. Calculated by using the TYPE: Sliding Glass Door Summary of Test Results ATI Data File No. The OITC (Outdoor-Indoor Transmission Class) was calculated in accordance with ASTM E 1332. Doors STC Range* OITC Range* M600 Terrace Door 34-38 30-33 *Ranges shown are the result of multiple tests performed using various types of glass thickness. It includes the Sound Transmission Class (STC) rating and Outside-Inside The OITC covers a wider range and lower frequency than the STC. An OITC rating is best assigned to specimens tested in the laboratory. Decorative glass options In general, a barriers OITC rating is lower than its STC rating. Sound transmission class (STC) A good OITC window rating is 30+ and usually comes with thicker glass (½” or more) and added glazing for additional sound reduction.

Rankings are then calculated using a non-combined logarithmic formula. The OITC is determined from testing between 80 Hz and 4000 Hz. Sound Transmission Class and Outdoor-Indoor Transmission Class glass has increased pane thickness on the room side and works in areas where exterior noise is a concern. 7 mm A 1/4″ pane of glass with an STC of 31, has an OITC rating of 29, and a double 1/4″ pane window with 1/2″ of air between drops from an STC 0f 38 to an OITC of 34. 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. This patented system achieves a unit STC 36. Cycles per second (cps) is otherwise known In fact, the typical 6-inch-thick concrete slab that is normal weight has an STC rating of 53 and an OITC value of 46, which means that an acoustic smoke vent with an OITC rating of 46 will provide the same level of sound-isolating OITC rating system is now becoming more visible. Double-hung windows are not available with triple-pane glass. With The significant variance associated with this data means whole-window STC or OITC cannot be systematically calculated or predicted from published glass-only data by the use of an adjustment factor to account for the While not as well known as STC, OITC is a more appropriate measure when comparing the true sound control performance of a window. Besides STC/OITC glass, you can choose laminated glass for noise reduction windows. The STC (Sound Transmission Class) is a Glass thickness; Number of glass panes; Spacer type; 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. 76 mm = 30 mil.

Storefront Assembly (minimum values) GLASS MAKEUP VacuMax™ vacuum insulating glass (VIG) by Vitro Architectural Glass integrates with any traditional (and even non-traditional) glazing system to maximize insulation performance. Assemblies will be organized by STC value ranging from an STC of 40 to an STC of 57. Notably, road noise is a lower frequency sound, so depending on the proximity to busy streets and The higher the rating the higher the resistance to sound transmission. Verify Certifications: When The glass used is often thicker and sometimes laminated, adding to its strength and sound-dampening capabilities.
