Materials

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that are useful in many building materials and consumer products but have a large potential for harm.   The goal of this report is to inform and inspire building owners, architects, designers, building product manufacturers, and government decision makers to eliminate unnecessary uses of PFAS and to promote the design and use of safer non-PFAS alternatives.

Digital collection of tools and guides to help designers, architects, homeowners, and developers make more informed choices about building materials and health.

More than 100 product guides to support practitioners in selecting products that avoid negative health impacts.

Database containing information on chemical hazards and risks of selected groups of building products and providing guidance for making informed product selection. Resources also include drop-in specification language, manufacturer information request templates, guidance for decoding product-specific literature, case studies and online courses specific for the featured product groups.

HBN's Product Guidance uses a red-to-green ranking system to compare different types of products based on their hazardous content. It is informed by our comprehensive research into the hazards associated with building products that may impact building occupants as well as fenceline communities and workers throughout the product's life cycle.
