What is Formaldehyde-Free insulation?
Formaldehyde-Free insulation is a fiberglass insulation that uses a different “binder”, or glue, to hold the glass fibers together. The binders allow a manufacturer to shape the insulation products they produce and give those products the strength and recovery required to fill a wall cavity. The recovery of insulation is key since there is such high compression used to package the products in the factory. Tests have shown that Formaldehyde-Free insulation has problems with recovery and tensile strength. Further tests have been done by state and federal agencies on formaldehyde emissions of many construction materials and other items in the typical home. In all cases the conclusion was that the emission rate from fiberglass insulation did not significantly affect the indoor air quality of the home. Rockweiler Insulation uses regular fiberglass insulation because we believe the quality of the insulation product is compromised as a formaldehyde-free product.
