Does Owens Corning insulation have formaldehyde?

Traditional Owens Corning insulation did contain formaldehyde, but most of its current residential products are now made to be formaldehyde-free. For decades, fiberglass batt insulation across the industry used a phenol-formaldehyde binder to hold the glass fibers together. That binder could off-gas small amounts of formaldehyde, especially when first installed. Owens Corning addressed this concern by reformulating its products. Since around 2019 to 2020, the majority of Owens Corning residential fiberglass products, including EcoTouch Pink Fiberglas and the newer Pink Next Gen Fiberglas, are made with a 100 percent bio-based binder and are certified as formaldehyde-free and made with natural plant-based materials. These products are also certified to GREENGUARD Gold and are validated to be formaldehyde-free by third-party testing. However, some specialty or industrial Owens Corning products, such as certain high-temperature or mechanical insulation boards and older stock that may still be in distribution, may still use traditional binders. If formaldehyde is a concern for you due to chemical sensitivities, look for the specific label that says Made with 100 percent Natural Materials and Formaldehyde-Free, and check the product data sheet. Johns Manville and CertainTeed also offer formaldehyde-free options, and mineral wool like Rockwool never used formaldehyde binders at all.
