Power tool being used on insulation


Prefer fiberglass, formaldehyde-free mineral wool, or cellulose insulation. If board insulation is required, prefer expanded cork, halogen-free polyisocyanurate, or rigid mineral wool insulation. Avoid foam insulation, whether board or spray-applied, whenever possible. Use mechanical installation methods, such as fasteners, to avoid unnecessary use of adhesives. Prefer products with full disclosure of content through Health Product Declarations (HPDs).

Proposed procurement goals: 
  • At least 80% of insulation purchased by the municipality or used by contractors meet the HomeFree Green or Yellow level including formaldehyde limits for fiberglass or mineral wool batts, prohibition of two-part spray polyurethane foam, and halogenated flame retardants
  • Preference given to products with publicly available information to encourage the use of building products that are working to minimize their environmental and health impacts
    • Material ingredients documentation demonstrating the chemical inventory of the product to at least 0.1% (1,000 ppm) with all content characterized and screened
