Zola Windows has introduced its Sanctuary Glass to reach acoustic performance through a combination of wide asymmetrical spacing between panes, sound absorbing lamination and thick glass panes in differing widths. This glazing, combined with Zola’s existing sealed and thermally broken window design, ensures that Sanctuary Glass products deliver not only sound protection but also energy performance and visible transmittance.
Ready to include in any of Zola Windows’ product lines, Sanctuary Glass windows will ensure silence and tranquility deserved in a residence or office. Noise mitigation is important in buildings near busy streets or highways, train stations, and airports.
Whether you are concerned with minor sound dampening or you live in an urban environment where the highest acoustical performance is required, Sanctuary Glass will allow you to focus, relax and isolate yourself from the external din. With this special glazing package, an office will remain a quiet retreat; a home will be a sanctuary.
The Sanctuary Glass configuration can be used with any of the product lines from Zola Windows, and has certified third party testing results reaching up to 44 STC and 37 OITC. Zola has worked with third parties to test and verify performance in a few sample windows:
- 44 STC and 37 OITC Thermo Clad Sanctuary Glass tilt-turn windows
- 44 STC and 35 OITC American Heritage Simulated Double Hung (SDH) Sanctuary Glass tilt-turn windows
- 40 STC and 35 OITC Thermo uPVC Sanctuary Glass tilt-turn windows
STC, or Sound Transmission Class, measures transmission loss between 125 Hz and 4,000 Hz. This range covers most common sounds – human speech, barking dogs and more. The STC rating averages sound transmission results over a few points in between these frequencies. OITC, or Outside Inside Transmission Class, meanwhile, measures transmission loss from 80 to 4,000 Hz. The lower frequencies included in OITC mean that it is a better measure for blocking sounds often associated with transportation, speakers and subwoofers.
