Is CertainTeed insulation formaldehyde-free?

Yes, most current CertainTeed residential insulation products are formaldehyde-free, and the company has transitioned its entire residential fiberglass line to formaldehyde-free binders. CertainTeed Sustainable Insulation fiberglass batts and rolls and InsulSafe SP blown-in fiberglass are manufactured with a plant-based, bio-based binder that contains no added formaldehyde, phenols, or acrylics. These products are GREENGUARD Gold certified for low chemical emissions and have been verified by third-party testing to meet strict indoor air quality standards. This transition mirrors the industry shift that Owens Corning and Johns Manville also made around 2018 to 2020, moving away from traditional phenol-formaldehyde binders that could off-gas trace amounts of formaldehyde, especially when first installed. Older CertainTeed fiberglass insulation produced before approximately 2015 may have used a formaldehyde-based binder, as was standard across the industry at the time, but any product you buy today at Lowe's, Home Depot, or a lumber yard is formaldehyde-free. CertainTeed's product data sheets and packaging explicitly state Formaldehyde-Free. Its other product lines, such as rigid foam boards and MemBrain smart vapor retarder, also do not contain formaldehyde. If you have chemical sensitivities, you can confidently use current CertainTeed Sustainable Insulation, and for maximum assurance look for the GREENGUARD Gold label on the package.
