Crystal Window AC85 Acoustic Window Receives Industry Recognition Members News January 13, 2021 National manufacturer Crystal Window & Door Systems and its impressive product line continue to receive fenestration industry recognition. Leading national trade publication US Glass Magazine named the Crystal Acoustic Window AC85 Aluminum Window the winner in the façade/glazing systems category of its annual “Readers’ Choice Awards,” featured in the December 2020 issue. This is the second year in a row and the third time in the past five years that a new Crystal product was picked as a favorite. “The Crystal Series AC85 Acoustic Window delivers industry leading acoustic sound transmission reductions,” said Sabrina Leung, Crystal’s R&D/Architectural Sales Manager. “Independent lab testing of the AC85 window for a recent project in New York certified an outstanding Outdoor-Indoor Transmission Class (OITC) sound reduction rating of 42 using double pane insulated glass. This means properties in high noise areas near highways, rail lines, airports, or heavy traffic can use these windows to provide very comfortable interior environments.” The aluminum frame Crystal AC85 Acoustic Window is available in either casement or fixed window styles. The heavy-duty aluminum 7-⅞” depth thermally-broken master frame window features a dual-sash configuration for both styles. For the casement, the interior sash opens in and the exterior sash opens out. The AC85 dual sashes each have a 1-¼” glazing pocket which accepts double or triple pane insulated glass units. With appropriate glass, Low-E coatings, and argon filling options, notable U-values of 0.28 are achieved. The US Glass Readers’ Choice Awards are determined by the publication’s national and international subscribers voting online during November for the most impressive new products featured in the publication during the year. Crystal was a previous Readers’ Choice Award winner in 2019 with its Magnus Commercial Vinyl Series 4500 uPVC window line and in 2016 with its aluminum Series 8500/8600 projected window line.
