Certified Faced Insulation” is the certification designation granted by the Home Innovation Research Labs (formerly National Association of Home Builders), a third-party testing service, to vapor-retardant-faced insulation produced by an insulation laminating company and certifies that the insulation thus certified meets certain minimum standards, such as width, length, and R-value. “Certified Faced Insulation” is a certification used by fiberglass laminators. Only insulation that has been laminated using NAIMA 202-96 certified insulation can meet the requirements of the Certified Faced Insulation certification.
