Soundproofing Windows in Dumbo
December 3rd, 2007
A NY Times article on Sunday by C.J. Hughes gave mention to Dumbo’s J Condo at 100 Jay Street. C.J. Hughes writes about the increase of E Zones in NYC. “In 2007, 16 E zones were created, involving hundreds of blocks, versus four zones in 1996.” E zoning designation, typically means that it abuts a busy nonresidential area and that developers must take extra noise-abatement steps. Both J Condo and Beacon Tower are new condo developments in Dumbo that abuts the Manhattan Bridge on opposite sides. J Condo hired soundproofing consultants, Architectural Testing to minimize the bridge noise. Beacon Tower at 85 Adams Street hired Shen Milsom Wilke, a New York-based acoustical design firm, to evaluate and measure the site noise. Their windows feature heavy panes of laminated glass separated by eight inches of air space and rubber gaskets, to dramatically reduce the sound levels. According to Shen Milsom Wilke, it was found that sound levels intermittently peaked at 96 dBA due predominantly to the train passing by every few minutes at the 5th floor level.
With the proximity to the Manhattan Bridge, Brooklyn Bridge, and the Brooklyn-Queens Expressway, most of Dumbo is noisy, and many existing buildings have been around before zoning required extra noise-abatement steps. If you don’t live in one of the two new high-rises, you still have options for a quiet night at home or at your business. Two companies that soundproof windows in the Dumbo area are Cityproof and Citiquiet. I’ve spoken to several residents of Dumbo who have hired both to install soundproofing windows. In most cases, window frames that match the existing windows are installed in the framing or behind the exterior window, leaving alternating layers of air and thick glass. Ordering custom windows typically take 6-10 weeks for delivery, but installation takes a few hours. (Photo of installed soundproofing window above). Based on personal experience and talking with residents of J Condo, Beacon Tower and residents who soundproofed other older apartments, the windows make a huge difference. Walking into one of these apartments make one forget that there are any cars or subways outside of these apartments. One side effect of soundproofing — you notice more of your interior noise such as a noisy refrigerator and central fan while exterior street noise is kept out.
