Residential Sound Insulation Program Issues Resolution

​​
For 25 years, the Residential Sound Insulation Program (RSIP) has worked to mitigate airport noise on behalf of the communities near Chicago’s airports. The Program is designed to reduce the effects of aircraft noise inside the home, with the goal of achieving a quieter environment and better quality of life for residents located within the highest impacted areas affected by aircraft noise. To date, the City has sound-insulated more than 21,000 homes near O’Hare and Midway.

Recently, the State of Illinois enacted legislation, 30 ILCS 105/6z-20.1, .2, and .3, and 65 ILCS 5/11-101-3, which will provide funding for the Chicago Department of Aviation (CDA) to replace confirmed odorous windows and doors with entirely new windows and doors, and which establishes eligibility requirements, a general procedure for replacement, and provides for additional in-home air quality testing in a limited number of homes.  The CDA is now working to implement the state legislation, and is working with the State and the advisory committee pursuant to the legislation to fulfill the responsibilities and achieve the goals set forth in the legislation.  The replacement process pursuant to the legislation is in its initial stages of development. 

A notice will be mailed at a later date to each homeowner that participated in the RSIP describing the process and deadlines for requesting odor inspections which will be used to determine eligibility to receive replacement wind​ow and doors for homes that have a confirmed odor.  Residents in homes where offensive odors have already been confirmed do not need to request an additional odor inspection.  The right to request an odor inspection and seek replacement is not affected by any odor related claims made or odor related products received from the RSIP prior to June 5, 2019.  

Odorous windows have been reported by a small percentage of homeowners. In order to respond to these concerns, CDA established an odor inspection protocol and hired two independent experts to conduct in-home and laboratory testing to identify and measure the compounds emitted from the windows.

The two independent experts concluded that there is no evidence that RSIP window products or the odors emitted from them pose a threat to health. Extensive testing by both an industrial hygiene expert and an architectural testing expert have determined that the primary source of the window odor​s is the PVC-coated screens found in many window installations. As referenced above, the CDA is now preparing to implement state legislation providing funding for window and door replacements in homes with a confirmed odor.

The CDA has revised the window specifications for all future RSIP phases to prevent the use of PVC-coated screens and requiring testing of select window products before they are installed in homes based on recommendations provided by the third-party architectural experts.  

More information regarding eligibility for window repairs and replacements as part of the mitigation program can be found below. The CDA remains engaged with the community, and invites residents to get in touch with any questions regarding the mitigation program, and/or to schedule an inspection if they are experiencing any issues with windows in their homes. ​

Additional Information

In 2017 and 2018 the City of Chicago ordered testing to determine the source of odors associated with some of the vinyl windows installed as part of the RSIP. All of the testing reports are provided below.
