Protection against forced entry. 20-min : Y . Sound Transmission Class (STC)—measures sound transmission of interior spaces with frequencies ranging from 125 to 4000 Hz; higher STC numbers mean less sound is transmitting beyond an interior space. Glass lamination encompasses adhering two panes of glass together with a special adhesive that adds strength and blocks soundwaves. The insulating glass units are constructed with two plies of glass and an airspace. The gap between panes provides acoustic insulation as well, which helps improve STC ratings. By comparison, a ¼” laminated glass has an STC rating of ~34 dB. Sound Transmission Class ratings. [25] Sound leakage 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.

The attached STC and OITC data is for glass only and that the final STC rating of the window assembly could vary because of the influence of the acoustical performance of the framing members and the construction of the window assembly. Operable windows also include a convenient mesh screen Reduces UV radiation by 99% reducing fading up to 8. STC is highly dependant on the construction of the partition. Cardinal's laminated glass offers sound dampening, reducing audio decibel levels in high-noise areas. 5+10*2. Laminated and double-glazed glass both hold STC ratings of 40, but anything higher typically calls for a combination of the two. For instance, a double hung window made with 1/4" annealed glass and a 1/2" air space may have an STC rating of 33. It’s actually 2 pieces of glass with a piece of plastic in the middle. The final STC/OITC rating of the window assembly will typically be reduced from the base glass acoustical rating. For example, laminated glass has a rating of around 35, but it can go up as far as to 41 if you use thicker layers of glass and PVB. Registered Office: Saint-Gobain House, East Leake, Loughborough, Leicestershire, LE12 6JU. Safety Applications. The STC (Sound Transmission Class) rating is a single-number rating system for interior building STC. The final STC/OITC rating of the window assembly could vary because of the influence of the framing members and the construction of the window assembly. Design Pressure: 30 - 50 psf. The However, it is important to note that different glass options and the use of combination units may affect the sound abatement performance of the unit. In general, a higher STC rating blocks more noise from transmitting through a partition. 5lg(M1+M2)+13+R1. Sound Transmission Class Sound Transmission Class (STC) is a single-number rating system that assigns a value to a product to indicate how well that product insulates against unwanted noise within the Gaps or weaknesses in the frame can compromise the STC rating.
