Code Acceptance

Building code organizations and related agencies recognize Dricon® FRT wood as an alternative to materials classified as noncombustible for a range of applications.  The uses for fire retardant treated wood as an alternative to noncombustible materials are specifically noted in the model building codes, downloadable below. In general, the codes permit the use of fire retardant treated wood in specific components and/or locations as an alternate for noncombustible materials in cases when combustible materials including untreated wood are not permitted.

The model building codes require that every piece of FRT wood bear the identification mark of an approved inspection agency. Each piece of Dricon® FRT wood is marked with an ink stamp bearing the classification mark of Underwriters Laboratories, Inc., describing its surface burning characteristics. The mark further identifies the name and location of the treating plant and will show that the material complies with AWPA standards, has been dried after treatment and qualifies as an Interior Type A, low hygroscopic product.

Dricon® FRT wood has been evaluated and issued a report (ESR-1626) by International Code Council (ICC) Evaluation Services, providing evidence that it meets the requirements of model building codes for interior FRT wood. ICC creates model building codes used throughout the U.S.; its evaluation reports are accepted in nearly all cases by local building officials. To download ESR-1626, click here (PDF).

Compliance with Industry Standards

The American Wood Protection Association (AWPA) develops standards for the wood preserving industry in the United States to ensure that treated wood products perform satisfactorily for their intended use. Dricon® FR chemicals and Dricon® FRT wood are acceptable under AWPA’s P & U standards.

An editable model specification is provided here as a convenience to architects and design professionals to ensure that products purchased for a given project meet their intentions. Model specifications typically include criteria defined in building codes and industry standards, but may also include additional characteristics, such as warranties, third-party certification and special properties, to provide desired features. As such, this model may be edited. We present it in electronic form as a service in order to save time and paperwork for specifiers.
