AY DOCUMENTS

Technical and informational documents published by the Spray Polyurethane Foam Alliance (SPFA) for use by members and distribution to the public. (The “AY” designation was developed as part of a numbering system by the Society of the Plastics Industries. All documents originating within the spray polyurethane foam organization were numbered “AY-xxx.”)

SPFA believes that the path to a healthful, safe, high-quality and performing SPF installation travels through the hands of a knowledgeable, trained, experienced, and ideally PCP-certified professional contractor.
