Steps

  1. Go to the NFRC Certified Products Directory search tool at search.nfrc.org/search/searchdefault.aspx (linked from nfrc.org/certified-product-directory).
  2. Filter by product type (window, door, skylight) and desired features to narrow the result list.
  3. Review matched entries for manufacturer, product line, and the NFRC label ratings (e.g., U-factor, SHGC) associated with each Certified Products Directory (CPD) entry.
  4. For commercial glazing products specifically, use the separate Commercial Products Directory at cmast.nfrc.org instead.
