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.

At face value, cabinetry may seem to be made of one type of wood, but its construction is much more complex. Many prefabricated cabinets are built using a combination of three or more wood composites and veneers, which typically use toxic glues containing formaldehyde, a known human carcinogen.

By comparing the material contents and construction in prefabricated cabinets, we created a spectrum that indicates the relationship between affordability and health. We typically consider the health effects during all phases of product development, but these diagrams are focused on the health effects during installation and inhabitation.

Currently, prefabricated cabinets are composed of 5%-30% healthier materials. Designers can increase this percentage by requesting manufacturers to build with NAF (no added formaldehyde) composite woods. This often comes with an increased price. Our Composite Wood Product and Spec Guidance gives a range of healthier substitutions.
