The Advantages of Fire Retardant Treated Wood


When it comes time to decide what type of material to build with, architects and homebuilders often choose wood mainly because of its aesthetically pleasing look and adaptability in design. Given concerns over the flammability of wood, many builders opt use fire treated lumber for their projects.

FRT wood, or Fire Retardant Treated Wood, is the chemical solution applied for this specific treatment. FRT wood is an excellent technique that significantly decreases the chance of a fire burning an entire building. Although FTR wood can still burn in the right circumstances, it does so much more slowly than regular wood meaning any fires are less likely to spread quickly.

Wood is a sustainable option in building material and using FRT wood makes it a safe, modern choice. Furthermore, there are a number of advantages to selecting lumber processed in this manner.
