Insulation

PRINT

The NIBS–IEQ Products & Materials committee realizes that insulation is an essential component in building systems to assure a comfortable environment. Insulation and insulating materials are generally hidden or covered, however emissions can still be encountered by building occupants. The Committee believes that polystyrene foam insulation is best tolerated by persons with multiple chemical sensitivities. Other insulating products, such as fiberglass, cellulose, or cotton/polyester blend insulating products may produce particulates, harbor mold, or emit problematic volatile fumes, depending on the product and the manufacturing techniques used.

The Committee has particular concerns about interior lined ductwork, due to the insulation's ability to collect and trap chemical contaminants, dusts, microbes and fungi, as well as emissions from the adhesives used to secure the insulation. It is recommended that no interior-lined ductwork be used in the construction of buildings meant to be accessible to persons with MCS.

Lastly, insulation used anywhere in buildings must not contain urea-formaldehyde resins.
