Exterior Fire Retardant Treated Wood

Fire retardant lumber is essential to creating a safe building. Exterior fire retardant treated wood is one type of fire retardant lumber that is especially important to maintaining a safe building. Exterior fire retardant treated wood is used for specifications that will have a lot of exposure to the elements or high humidity. Even under these harsh conditions, exterior fire retardant treated wood will still maintain a fire rating.

Flameproof Companies’ exterior fire retardant treated wood has a clear finish. However, the wood can be stained with a stain that is water-based, or it can be painted with a latex-based paint. Additionally, it can be used in any way that untreated exterior fire wood is used. There’s virtually no logical reason not to use exterior fire retardant treated wood.

This lumber is manufactured in the Chicagoland treating facility, but it is available for immediate shipment to nationwide locations. Flameproof Companies are so passionate about creating safe buildings by using exterior fire retardant treated wood that they offer on-site deliver to locations nationwide. Any size order can be delivered by a forklift unload, crane service, or by a vehicle. Exterior fire retardant treated wood is important for responsible construction, so Flameproof Companies make it as easy as possible for companies to use.
