No-Burn Plus ThB

Spray on Thermal Barrier, Fire Resistant Paint

Thermal barrier base white fire-resistant paint for spray polyurethane foam insulation.

Product Overview

As spray polyurethane foam becomes the preferred insulation choice in commercial and residential construction, this highly combustible material requires a fire resistant paint or coating that may be installed on the interior as a thermal barrier spray to keep your building safe and fire code compliant.

No-Burn Plus ThB is an intumescent fire protective coating for interior and unconditioned spaces, where spray polyurethane foam insulation is installed. Used as a component in an alternative thermal barrier, an alternative ignition barrier, and/or an exterior fire rated wall assembly, No-Burn Plus ThB passively protects the spray foam insulation in the event of a fire by delaying the rise in temperature, which in turn delays or prevents the spray foam from igniting.

Prior to using No-Burn Plus ThB, our fire resistive paints were very inconsistent quality. This led to downtime, problems in the field, and problems maintaining equipment. Since using No-Burn Plus ThB, our efficiency has picked up drastically and now we can worry about the things that matter most. Make no mistake, No-Burn is the best, most user-friendly product of its kind.
