Intumescent Coatings for Spray Polyurethane Foam Insulation
To keep a building up to code, spray polyurethane foam insulation (SPF) must be separated from the interior of a building or occupied living spaces by a spray foam thermal barrier or an approved alternative thermal barrier assembly.

There’s no need to use sheetrock or an equivalent to protect spray polyurethane foam insulation — a site-applied coating of No-Burn Plus ThB provides an approved thermal barrier as required by international and national building codes, including the IBC, IRC , and NFPA Life Safety 101 code. No-Burn Plus ThB passes the burn tests required for code compliance, providing approved protection for a wide variety of foam insulation brands.
In certain attic and crawlspace applications, the building code permits an igniton barrier for spray polyurethane foam insulation. No-Burn offers both thermal and ignition barriers with No-Burn Plus ThB and Plus XD intumescent coatings that create a char-barrier in the presence of flame, protecting the insulation beneath.
Designed with professional installation in mind and manufactured in compliance with ISO 9001, No-Burn Plus ThB and Plus XD are water-based, non-toxic, and low VOC.
