Since 1971, Chicago Flameproof & Wood Specialties Corp. has been a long-standing manufacturer of Fire Retardant and Preservative Treated Lumber & Plywood providing a wide range of services and finished goods backed by excellent distribution capabilities. What began as a small treatment facility on the outskirts of Chicago has grown into The FLAMEPROOF Companies, but with a growing national presence. Now serving as the Corporate Headquarters for FLAMEPROOF Companies, Chicago Flameproof continues to provide quick turn around and on time delivery on hard to find Fire Retardant and Preservative Treated products. Our customers benefit from working directly with a manufacturer who understands the time sensitive demands of today’s construction industry.
