A review of the health effects of energy conserving materials.
The energy conservation movement has promoted both greater use of insulating materials and the reduction of heat losses by sealing air leaks. The release of volatile or airborne materials from the installation of these building materials under these conditions has resulted in an exacerbated indoor air pollution with the potential for certain health and safety hazards. Consequently, a comparative review of the health and safety hazards, exposure standards, and regulatory action associated with the more commonly used insulating materials with particular respect to current energy conservation measures was undertaken. The materials reviewed included asbestos, urea-formaldehyde foam, polyvinyl chloride, cellulosic insulations, fibrous glass, mineral wool, and vermiculite. Although no longer used, the past installation of asbestos in a friable form is the greatest potential health hazard. The exposure to formaldehyde gas from its release from urea-formaldehyde foam has elicited subjective complaints of sensory irritation and unresolved controversy and regulatory action regarding its toxicity to humans. Lesser health problems have been associated with the more widely used fibrous glass and mineral or rock wools.
