InsulBloc gains ICC approval

InsulBloc received ICC approval based on 2012 building codes.
A new International Code Council (ICC) Evaluation Service report gives approval for SPF insulations, based on 2012 building codes, to InsulStar (residential) and InsulBloc (commercial) closed-cell spray foam insulations from NCFI Polyurethanes.

The report, ESR-1615, for InsulStar and InsulBloc does the following:
  • Approves both insulations for use as a vapor retarders, air barriers, and as air-impermeable insulations
  • Includes evaluation of DC-315 as an alternative thermal barrier coating
  • Recognizes use of both insulations as water-resistive barriers
  • Recognizes InsulBloc for all building types (I, II, III, IV and V under IBC) and InsulStar for all dwellings under the IRC.
Jason Hoerter, P.E., senior product manager with NCFI, says the ICC report better defines for code officials and builders how the products can, and are, used.

“Former reports were not as clear and precise as this new release,” says Hoerter. “Our technical staff spends a great deal of time working with code officials, architects, builders and spray foam contractors interpreting the language and educating each other on its intent. This report does a very good job making it concise, and provides a chart that will help U.S. building stakeholders not only choose the best products for the job, but also guide them in applications. Plus, it tests according to new 2012 codes, so they can trust they have the most up-to-date product information.”
