Wilmington, Delaware – DuPont Performance Building Solutions has reformulated its Thermax polyisocyanurate insulation to remove halogenated flame retardants. The company claimed it is the first Class A PIR sheathing manufacturer to phase out the halogenated flame retardants commonly used in building insulation polyurethane foams.
The Thermax Non-Halogen (NH) Series products are the first polyiso, Class A, non-halogen and LBC Red List Approved products in the North American above-grade commercial wall systems market, DuPont said.
‘DuPont is proactively leading this reformulation in support of the company’s Safer by Design 2030 sustainability goal,’ Kieran Carlisle, the company’s global innovation leader, said. ‘This innovation advances our business sustainability vision, which includes a Safer by Design commitment to collaborate with our customers and key partners to bring green chemistry innovations to market and drive continued reduction in the presence of priority substances in our portfolio.’
He added that the company is committed to voluntarily providing transparency documents for its products. ‘Hand in hand with the reformulation of our Thermax line, we have been working with a third party, GreenCircle Certified, to validate the ingredients in our products as well as providing our customers a Declare label via International Living Future Institute (ILFI),’ he said.
LBC Red List Approved designation indicates that 99% of ingredients present and disclosed, at or above 100 ppm, in Thermax NH Series products, do not contain any Red List chemicals. This designation can be used to obtain LEED v4 and v4.1 credit.
