What is Fire Treated Lumber?

lumberAre you wondering, “What is fire treated lumber?” If so, you are at the right place for an answer! Chicago Flameproof has been providing builders with fire retardant products for over 40 years, so you can trust our expertise.

Fire treated lumber is lumber that has been treated with fire retardant preservatives. That means that in the unfortunate case of a building fire, this lumber will burn more slowly than untreated lumber would burn, which allows for more time for the fire to be put out. This could prevent extra damage to the building’s exterior and interior alike! It is an absolutely amazing feature.

Here at Chicago Flameproof, we carry a full line of fire treated lumber that is suitable for any building project you may have. Not only is our company FSC Certified, but it is also located in three different states, and we ship our products throughout the entire United States! You can reach us at our Chicago location at (866) 884-7591, at our Wisconsin location at (866) 884-7593, or at our North Texas location at (866) 884-7594.
