InsulStar Meets Latest IBC, IRC and IECC Codes

Mount Airy, NC – InsulStar®, a high performance closed-cell Spray Polyurethane Foam insulation manufactured by NCFI Polyurethanes, is in compliance with the 2006 International Building Code, International Residential Code and International Energy Conservation Code, according to a report released by the California-based nonprofit group ICC Evaluation Service, Inc (ICC-ES). This compliance includes being the only closed-cell spray foam evaluated for use in unvented attics, per the 2006 International Residential Code.

Don Schumacher, Director of Sales and Marketing of NCFI, pointed out the importance of such a report. “As high energy prices become a major issue, people are looking for new ways to lower their utility bills, and InsulStar® is becoming more and more popular because it cuts energy costs by as much as sixty percent. It’s important that people who choose InsulStar® know that it’s code compliant,” he said. He noted that InsulStar® insulation may be applied to wood, metal, concrete and masonry, and gypsum board surfaces, making it one of the most versatile insulation materials available.

In compiling the report, ICC-ES noted that InsulStar® meets the following 2006 IRC requirements:

• Allows unvented attic applications

• No additional vapor retarder normally needed

• 8 inches maximum thickness in wall assembly

• 12 inches max thickness in ceiling

• Lists R-values to the max installed thickness

• Job site certification provided for installer

• Allows exposed SPF on floors of vented attics

• Permits ignition barrier coating

In addition, InsulStar® meets Florida Product Approval for roof deck wind uplift resistance, helping prevent damage during hurricanes and other high wind events.

ICC-ES is a nonprofit, public-benefit corporation that does technical evaluations of building products, components, methods and materials and issues technical reports that directly address the issue of code compliance.
