Fire Treated Exterior Lumber

Using fire treated exterior lumber is one of the best ways to protect a building against fire damage. Fire resistant exterior lumber is usually used to construct areas that will have the most exposure to the harsh elements. This lumber is treated with chemical preservatives that help to slow down the process of oxidation that occurs when wood is burned.

There are a lot of benefits to using fire treated exterior lumber. Because the chemical preservatives slow down the process of oxidation, the wood will burn more slowly if it is to catch fire.  In effect, occupants will have more time to safely evacuate the building. This will slow burning process may also minimize the amount of fire damage.
