Spray polyurethane foam insulation and health

Spray polyurethane foam (SPF) is mainly used to insulate the floors of existing homes. It’s two main components undergo a chemical reaction, causing it to cure into an insulating foam layer. It is important that this process proceeds completely, otherwise substances may be released that can cause health problems. When SPF home insulation is installed correctly, residents are unlikely to experience any associated adverse health effects. This will ensure that any exposure to hazardous substances remains within safety limits. However, if this material is applied incorrectly, these limits can be exceeded, causing it to pose a greater health risk. Due to inadequate registration, the health issues reported by residents still cannot be properly interpreted. The Council recommends that registration be improved. The Council also feels that insulation companies must provide guarantees to residents that they operate safely and in compliance with the guidelines. Finally, the Council recommends that the risks posed to workers be further investigated.
