Fire Treated Lumber for Exterior Use

wooden building constructionChicago Flameproof’s fire treated lumber for exterior use is a great product to use when starting a building project! It can be used in the same fashion that untreated lumber is used, but this lumber has been treated with fire retardant preservatives. Due to this treatment, this lumber will burn more slowly than untreated lumber would burn if ever in the position of catching fire. This allows for more time for the fire to be put out and could prevent extra damage to the building’s exterior and interior!

Here at Chicago Flameproof, we always have a full line of our fire treated lumber for exterior use in stock! Make sure that you are building with quality building materials by purchasing these amazing products today! Not only is our company FSC Certified, but we also ship our products throughout the United States!
