THE UK'S LEADING CHOICE FOR FIRE RATED AND SPECIALIST GLASS & GLAZING. Sound Transmission Loss (dB) 9/16" overall - 1/4" glass, . Graph 1 shows the sound transmission loss of glass across a low to high frequency range, comparing ordinary laminated and Acousta™ laminated glass. Although laminated glass is effective at reducing noise transmission, how does it compare to other types of glass? Acoustic laminated glass offers improved levels of noise reduction over regular laminated glass. Skyline Design’s acoustic IGUs include laminated glass and airspace to improve both thermal and acoustic performance. Pilkington Optilam™ is produced by combining two or more sheets of glass with one or more plastic interlayers. meaning that it has an Impact Safety Rating and can be used in Critical Locations. On the products, they were as mentioned, packaging was high quality, and delivery in these Download our datasheets for fire-rated, acoustic, laminated & toughened safety glass products. Recent technological advances in the manufacturing of the interlayer, contained within laminated glass, have shown an improvement in acoustic performance. The four-point increase in STC rating is the resuH of dampilg provided by the PVB intedayer used in the laminated glass. 1/2-inch of acoustic laminated yields an STC rating of about 38-39; Regardless of the selected soundproofing materials chosen, in general, all glass and glazing solutions adhere to five STC rating by increasing the air space alone. Acoustic Properties of Laminated Glass. Laminated glass Aside from being cost-effective, acoustic laminated glass panels will certainly earn you some Sound Transmission Class is a single number rating for glass’s efficiency in reducing noise transmission.
