What is the STC rating of laminated glass?
40
Laminated and double-glazed glass both hold STC ratings of 40, but anything higher typically calls for a combination of the two. Maximum noise insulation is achieved by laminating one or more lites in a double-pane piece.
Is 6mm glass sound proof?
Soundproof Glass For example, to achieve maximum soundproofing properties, a window or door can be fitted with a double-glazed unit of glass where the outside sheet is 10mm and the inside sheet is 6mm thick. Special studio quality SoundControl glass can be used in severe cases.
How thick should glass be for soundproofing?
The wider the space, the better the effect. The thickness of the total acoustic double glazing unit is important to consider as well. An IGU with an overall thickness of 12 mm (3mm of glass + 6 mm of air space + 3 mm of glass) is going to have less ability to dampen sound than an IGU that is 24 mm thick overall.
Is laminated glass good for soundproofing?
Laminated glass has a thin layer of polyvinyl butyral (PVB) sandwiched between two panes of glass to form the outer pane. PVB provides excellent acoustic performance by dampening soundwaves. The PVB prevents the glass from shattering, and the window stays in one piece, so security is also increased.
What does STC mean in glass?
Sound Transmission Class
Sound Transmission Class (STC) STC is used to measure a window’s ability to reduce sound. The higher the rating, the better the sound control. The typical rating for single pane windows is 18-20 while a double glazed window is 28-32.
What should my STC be for laminated glass?
Standard walls in most homes are 33 STC, while studio-level soundproofing requires a rating of at least 45. With this in mind, a mid-30s score might seem low, but it’s suitable for office spaces lacking all-glass construction. Laminated glass can increase an STC rating when cost and thermal insulation aren’t concerns.
What’s the minimum STC rating for a window?
STC window rating depends upon several factors – glass thickness, laminated glass, the airspace between panes, and how and what the frame is constructed of. A rating of 40 is the minimum for conversation privacy, and many building codes now require a rating of 50 to 55.
What does STC stand for in acoustic rating?
The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. Its original intent was to quantify interior building partitions, not exterior wall components.
How does OITC affect the acoustic rating of glass?
*OITC is estimated based on this test. Glass size and glazing system will affect STC rating. See additional notes below data for specific details. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance.
