A substance which expands as a result of heat exposure, creating a char‐barrier, protecting the coated substrate or surface from flame.
Visit the intumescent coatings page of No‐Burn®, Inc.’s website or contact the manufacturer’s office and ask for sales.
Each Evaluation Report, Evaluation Listing and Engineering Report issued to No-Burn®, Inc. verify the products have been tested to show compliance with specific requirements of the international (I-Codes), national, state and local code requirements. Of the utmost importance is the acknowledgement that No-Burn®, Inc.’s products are manufactured in ISO9001:2008 facilities, under additional third-party inspections as an Evaluation Report and Evaluation Listing holder. When you purchase and install No-Burn®, Inc.’s products, be assured the chemistry and performance quality are as tested because No-Burn®, Inc. is continually audited by independent third-parties.
Examples of acceptable applications have been given for your benefit in manufacturer’s literature. For specific questions, please contact the manufacturer’s office and ask for sales.
No‐Burn® intumescents are proprietary and patent pending formulations; copies of (M)SDS are available online at www.noburn.com.
Clients may select installer(s) from a national network. Specializing in the installation of No‐Burn® products, installers may also specialize in the installation of other building product materials, such as insulation, fireproofing, etc. For specific questions, please contact the manufacturer’s office and ask for sales.
Examples of acceptable application rates have been given for your benefit in manufacturer’s literature. Wet film thicknesses for acceptable applications are specified. For specific questions, please contact the manufacturer’s office and ask for technical support.
Yes. Temperature requirements shall be maintained during application (ER 305 Section 4.1 or UEL 5005 Section 3.1). Cure time is 24 hours; however, temperature requirements are not required to be maintained for 24 hours. Verification of all installation requirements is the responsibility of the certified installer.
In accordance with ER 305, No‐Burn® may be installed to meet the following fire performance requirements: fire resistance, non‐prescriptive thermal barrier, non‐prescriptive ignition barriers and surface burning characteristics for interior finishes.
Furthermore, No‐Burn® may be installed in accordance with UEL 5005 to meet surface burning characteristics (ASTM E84/ASTM E2768 extended 30 minute duration).

Yes. Representative assemblies were tested by accredited or certified testing laboratories using Evaluation Criteria (EC) 017 and Acceptance Criteria (AC) 14 procedures, which include standardized and modified ASTM E119 fire resistance protocol, respectively. Proprietary test reports were reviewed and accepted by the Evaluation Service IAPMO UES, demonstrating equivalence as required by Exception 4 of R302.13 (2018/2015) and Exception 4 of R501.3 (2012).
No. No‐Burn® reduces the spread of flame and smoke developed. In the unfortunate event of a fire, No‐Burn® limits the fire’s ability to consume the material; therefore, the smoke developed and smoke toxicity may be considered less threatening.
No. As a Class III vapor retarder, No‐Burn® does not restrict or limit the amount of moisture that passes through a material or assembly.
No‐Burn® intumescent coatings should be installed in accordance with manufacturer instructions. In most cases, No‐Burn® will be the finish coat on the substrate, which given the intended end‐uses, may likely have limited to no contact with typical sealants, termite treatments or other products. As a water‐based specialty coating, no special care is necessary once No‐Burn® is in place.
All No‐Burn® products have been tested in accordance with international standardized fire conditions, most notably ASTM E119 for fire resistance. Rated and non‐rated assemblies, where No‐Burn® Plus was applied to structural members, performed equivalent in quality, strength, effectiveness, durability and safety or met the fire performance standard prescribed in the International Building Code® (IBC®), International Residential Code® (IRC®), National Fire Protection Association® (NFPA®), etc. and the testing protocol of international standards, such as those previously listed above.
Intumescents manufactured by No‐Burn®, Inc. may be considered interior specialty coatings or paints. They do contain typical coating or paint particulates classified by the Occupational Safety Hazard Association (OSHA) as non‐hazardous, possible irritants, if inhaled while curing. Post curing, the intumescent(s) are inactive or static. In the case of activation, the intumescent(s) reduce the amount of smoke, by ceasing and limiting the spread of flame, by more than 50%. Intumescents manufactured by No‐Burn®, Inc. comply with strict VOC content and emissive regulations and green building standards.

No. The application of intumescent coatings does not negatively affect mechanical properties of the substrate.
The intumescents will resist certain amounts of water. As an interior, latex coating, No‐Burn® intumescents should have limited exposure to continuous wetting. If the substrate where No‐Burn® has been applied becomes compromised as a result of moisture, reapplication shall be necessary once the damaged substrate is reinstalled.
Tested to comply as an equivalent material to what is prescribed in the residential code, equivalence was established when all the exposed surfaces of the joist and subfloor are sprayed. No‐Burn® Plus sprayed to the joists and subfloor protects structural components in a more complete manner when compared to other options.
Penetrations or openings for ducts, vents, electrical outlets, lighting, devices, luminaries, wires, speakers, drainage, piping and similar penetrations or openings do not compromise the performance.
No. Standard hangers may be used.
