Toxic material reduction

BACKGROUND

Various chemicals are still used in the manufacture of building materials, despite known or suspected health hazards. Flame retardant chemicals, which are used to increase fire-resistance of materials, include PBDEs (polybrominated diphenyl ethers)—which, based on animal tests, are associated with potential neurobehavioral, carcinogenic and immune effects. Some of these chemicals can bioaccumulate in fat and result in food chain contamination, including human milk. All parts of this feature only apply to materials installed inside the weather proofing membrane of a project.
