Is there formaldehyde in Thermafiber blanket insulation?
The only component in Thermafiber blankets that contains trace amounts of formaldehyde is in the binder system (the glue that holds the fibers together to form a blanket). Even with this trace amount, blankets are cured in a high-temperature oven that virtually eliminates the free formaldehyde. Thermafiber blankets have been evaluated by an independent testing laboratory for emissions of formaldehyde. Results verified only trace amounts (12 ppb) of formaldehyde.
