SPF & ICC-ES AC377
ICC-ES Acceptance Criteria for Spray-Applied Foam Plastic Insulation (AC-377)
Traditionally the International Code Council Evaluation Service (ICC-ES) maintained acceptance criteria for SPF within the framework of another AC document entitled simply AC-12 Foam Plastic Insulation. Due to performance, application and manufacturing characteristics of SPF being different from that of other foam plastic insulation, the SPF industry, through SPFA, worked with ICC-ES to craft a separate acceptance criteria. This new acceptance criteria, AC-377 as it was approved in 2007, would eventually allow for the SPF industry to differentiate the unique performance aspects of spray foam, and demonstrate its compliance-points easily to the building code community.

UPDATES
Over the last year, the SPF industry has worked through SPFA with ICC-ES and many external industry stakeholders to modify, update and create new passages within AC-377 to keep up with the product, its performance and uses.
On June 3rd, 2009, the ICC-ES approved another change to AC-377, reflecting the industry's increased focus upon fire safety and testing, effectively altering several of the provisions related to SPF. Read the summary of changes, projected milestones and sunset dates, and other background on the project also linked at the bottom of this page (ICC-ES June09 Outcome Summary Fnl.pdf).
ICC-ES meets several times a year. Commonly acceptance criteria undergo changes on a regular basis to reflect the advances in safety, performance and product development, so it is imperative to maintain awareness and monitor the ICC-ES agenda for upcoming meetings. The webpage with materials for the June 3, 2009 hearing, with related AC377 attachments, letters, comments, etc are available here. Additionally, the original SPFA proposal is also available for download at the bottom of this page.
SPFA will post a notice and link on this page once the final version of the revised AC377 becomes available from ICC, which is likely early July, 2009.
For future meetings, ICC-ES typically posts agendas, or at least ACs up for consideration, here.
