SEALECTION® 500 IN CHANNEL 9 NEWS ORLANDO, FL 

DEMILEC USA wants to take this opportunity to correct some misleading statements from a recent 

story regarding the spray foam industry and our SEALECTION® 500 product. 

First and foremost, several spray polyurethane industry groups have been working to develop safe use 

and handling guidelines and protocol at the request of the EPA. This work predates this complaint and is 

unrelated, as it primarily addresses safety protocol for industry personnel during application and 

consumer guidance for do-it-yourself spray foam kits. 

Additionally, open-cell spray foam is water-blown with no CFCs, HCFCs or formaldehyde and 

SEALECTION®

 500 is not new to the industry, as it has a 20 year history in the construction market. 

Furthermore, based on toxicological assessment, SEALECTION® 500 completes its off-gassing within a 

few hours of application and DEMILEC USA maintains a 24 hour re-occupancy guideline. Also, 

SEALECTION® 500 is recognized by the National Association of Home Builder’s Research Center as a 

Green Approved product. 

In relation to the homeowners involved with this news story, after multiple site visits by DEMILEC 

USA personnel, DEMILEC USA contracted the services of a third-party indoor environmental 

consultant to conduct a full site investigation. His first visit included an initial indoor environmental 

measurement, including particulate matter and VOCs. He explained to the homeowners, this initial 

measurement is a baseline method and does not identify the individual components in the air. After the

initial visit, all parties involved (the consultant, DEMILEC USA and the homeowners) agreed upon an 

action plan that included completion of the thermal envelope, using spray foam, to be followed by 

complete indoor air quality testing. It was identified by DEMILEC USA and the consultant that a kneewall was required to separate the garage from the semi-conditioned attic, for both thermal performance

and to prevent chemicals or other contaminants from being drawn into the conditioned space from the 

garage. 

When the consultant returned to perform the scheduled air quality testing, the homeowners identified 

that the air quality measurements would be compromised due to their own “venting” and “filtration” 

efforts, therefore no analysis conducted. Later we were informed that the homeowners had conducted 

their own indoor air quality analysis. 

Due to our scheduled monitoring being cancelled, we continued to contact the homeowners, offering air 

quality analysis by our consultant, requesting to review their findings and offering to have our consultant

speak with their consultant about the results, to no avail. In the end, the homeowners chose not to work 

with us or allow our consultant to assist in determining the source of the problem. 

The unfortunate part of not being allowed to run conclusive testing is that the homeowner may never 

know the cause of their problem. While we are confident that the spray foam did not cause this issue, the 

creation of a sealed attic space reduces ventilation and may have helped to identify a pre-existing 

condition that is unrelated to the spray foam. Additionally, considering the foam could have easily been 

removed with no damage to the structure, the removal of their roof is an exaggerated approach with 

inflated costs that were unnecessary. 

DEMILEC USA stands behind our product SEALECTION® 500, which has been manufactured for over 

20 years and has been used to insulate hundreds of thousands of buildings across the world. This product 

is listed by ICC-ES and is manufactured under the stringent quality assurance program of Warnock 

Hersey.
