With OITC, the higher the number the more effective the sound mitigation properties. With STC, a higher rating means increased sound attenuation capabilities (and can be used on exterior glazing systems as well). ### Sound Mitigation of Glass Ron states: > Glass itself does not generally have good sound attenuation properties; however, adding an interlayer between glass lites offers great improvements. As such, laminated glass is typically chosen for projects that call for greater sound mitigation from glazing systems. Monolithic glass can still be used, but it should be paired with laminated glass in a double-glazed unit. > > A properly designed double-glazed office partition with a 3 ½-inch space between glass lites can offer, and even outperform, the soundproofing capabilities of a concrete wall of equal thickness. The larger the airspace between the glass lites, the better the sound attenuation properties. A double-glazed unit with a 6-inch airspace will achieve an STC rating of approximately 15 points greater than a double-glazed unit with a ¼-inch airspace. ## How St. Cloud Window’s Interior Windows Mitigate Sound We consider sound mitigation in all our interior windows and sound control room windows.
