In the spray foam industry, No-Burn® Plus and Plus XD intumescent paints are practical and economical options for meeting ignition barrier requirements. 

No-Burn® Plus and Plus XD act as a shield, protecting the substrate from the exposure or propagation of flame by surrounding the treated material with a protective char-barrier. These specialty products meet ignition barrier requirements for open and closed cell spray applied polyurethane foam plastic insulation as identified in the applicable sections of the International Building Codes (IBC), International Residential Codes (IRC), and Acceptance Criteria 377 (AC 377).  

According to AC 377, spray applied polyurethane foam plastic insulation installed in a crawl space where entry is made only for service of utilities, shall be protected by an ignition barrier as set in the IBC Section 2603.4.1.6, IRC Section R314.5.4 or Exception 4 of UBC Section 2602.4, except as noted in Section X2.0.
