Developed by the architecture firm Perkins + Will, Transparency is a website to “put the precautionary principle into action” in the building industry.   The site allows users to identify toxic chemicals in building products.  You can search by  chemical of concern, product, project area, Masterformat specification, health hazard, or environmental hazard.  Site also includes articles, background description of precautionary principle, and information about efforts to get toxic chemicals out of building materials.

PFAS in Building Products

Polyfluoroalkyl substances (PFAS) are a class of chemicals widely used in the building industry.  PFAS are persistent, bioaccumulative, and those that have been studied have been shown to be toxic at very low levels.


Safer Insulation Solution

Many insulation products contain halogenated flame retardants and other toxic chemicals.  This site, a project of Green Science Policy Institute, describes different insulation materials, including their environmental and health impacts.  Information is also included about advocacy efforts to increase the safety of insulation.
