110 Years of FPL: Early Fire Retardant Treatments

In celebration of 110 years of research at the Forest Products Laboratory (FPL), we are revisiting blog posts that detail some of our most interesting historic people, places, and projects. Enjoy!

In the early days of developing fire-retardant treatments, researchers at the Forest Products Laboratory (FPL) investigated about 130 treatments. Combinations of chemicals were used to obtain the best performance for both fire resistance and other performance properties, such as corrosion, leaching, gluing, finishing, and cost.
