The Solution For Responsible Building

There is growing concern over formaldehyde. Increasingly, state and federal health and environmental agencies as well as architects and sustainable building designers are recommending that exposure to formaldehyde be reduced. In fact, in its comments to the USGBC's LEED-NC v2.2, US EPA recommended that exposure to formaldehyde be minimized as much as possible. This is especially true in healthcare, education, residential and office settings. According to the US EPA and the California EPA, one important reason to minimize formaldehyde exposure is because formaldehyde is recognized by the International Agency for Research on Cancer as Group
1 - known to cause cancer. California EPA has also determined that formaldehyde is a toxic air contaminant often found indoors at levels in excess of health-based guidelines and recommendations.

To promote the health of building occupants, particularly in healthcare, educational, residential and
office situations, one obvious way to help minimize formaldehyde exposure is to use JM Formaldehydefree™ fiber glass insulations to eliminate one source.
