Fire Treated Lumber in Chicago

At Flameproof Companies, we are dedicated to providing fire treated lumber in Chicago, Wisconsin, and Texas. Using fire retardant lumber is important to creating safe buildings. Chemical preservatives are applied to wood products to create fire treated lumber. These chemical preservatives slow the oxidation process that occurs when wood is burned, which slows down the pace in which the fire spreads.

Although there are also Flameproof Companies in Wisconsin and Texas, we first started manufacturing fire treated lumber in Chicago. Chicago Flameproof is our full-line supplier of fire treated lumber in Chicago. We provide FlameTech fire treated lumber in Chicago, as well as in Wisconsin and Northern Texas. If you are in need of fire retardant lumber but do not live near these distribution centers, we can, and frequently do, ship our fire retardant products to onsite locations across the nation.

Our D-BLAZE fire retardant wood products are UL-classified and equipped with an FRS rating exhibiting a flame spread and smoke rating of 25 or less.  Our products are durable, non-corrosive, non-hygroscopic, and come with a 50 year warranty.

If you are in need of fire treated lumber in Chicago or any other location throughout the United States, call us at (866) 884-7591.
