Odorous Window Status
The CDA released reports in October regarding solutions for odorous windows. One report stated that there was no imminent danger due to chemicals in the air. California standards were used as a guideline. Tests were done during the summer and in the winter. The tests concluded there were no health issues.

InterTech was hired to solve the odorous window problem. They determined that the odor was caused by the PVC coating on fiberglass screens. The screens were removed the odor went away, but not entirely. Another test technique was to drill vent holes to release the vinyl odor without compromising sound insulation. They also wiped the window sashes with mineral spirits to diminish the odor.

Construction specs are being analyzed for future sound insulation window placement to ensure the problem is solved.

A total of 195 inquiries have been made from O’Hare residents, 134 were validated as having odorous windows. CDA will continue to take each call and validate accordingly.

To date 11,540 homes have been sound insulated in the O’Hare region with just 134 homes affected by odorous windows and 10,175 homes in the Midway region and 500 homes verified.

Fly Quiet Program—Sound Insulation Impact
Catherine Dunlap, Technical Committee Chair, shared her concerns regarding the potential changes to the Fly Quiet Program. She felt it might impact the Record of Decision(ROD) regarding which homes would receive sound insulation based on the full build out noise contour. The CDA staff presented the Residential Committee with three graphics of runway utilization: 2015 Estimated Runway Utilization in use today, Estimated Runway Utilization beginning in 2020 with Runway 9C/27C in use, and Estimated Runway Utilization at OMP Build Out.
