CertainTeed Introduces a Formaldehyde-Free Batt Insulation

Most fiberglass batt insulation is made with phenol formaldehyde or urea-extended phenol formaldehyde to bind the glass fibers together. And though formaldehyde exists naturally at low levels in the atmosphere, it is labeled a known carcinogen by the International Agency for Research on Cancer (IARC).
