Exterior Fire Treated Wood

Exterior fire treated wood is used for parts of a building that will have regular exposure to the elements or conditions of high humidity. For these specifications, Flameproof Company’s exterior fire treated lumber products are the products of choice. These wood products are ideal for applications such as decks, balconies, and siding.

Flameproof Companies’ exterior wood products are manufactured in our Chicagoland treating facility, and are available for immediate shipment to nationwide locations. Flameproof Companies’ on-site delivery options can provide any size order via vehicle, crane service, or forklift.

Flameproof Companies’ exterior fire retardant wood products have been submitted to both the ASTM E84 testing for surface burning characteristics and to ASTM D2898 for accelerated weathering (rain) tests. However, exterior fire retardant products are not rot resistant. Therefore, it is suggested that cedar fire retardant wood products be used for outdoor applications, as it is a species of lumber that is naturally rot resistant.  

The exterior fire treated wood products offered by Flameproof Companies have a clear finish, but they can be stained with a water-based stain or painted with a latex-based paint to reach a desired finish.
