FRT Exterior Treated

lumberFRT exterior treated wood is a great material to choose when starting a building project. It can be used the same way regular wood is used, but it has been treated with fire retardant preservatives. This means that in the unfortunate case of a building fire, this wood would burn more slowly than untreated wood would burn, which grants more time for the fire to be put out. This could prevent extra damage from happening to the building’s exterior as well as its interior! Why would anyone choose to use untreated wood when FRT exterior treated wood is available? Chicago Flameproof carries a full line of FRT exterior treated wood! Make sure you are building with quality materials and purchase your FRT exterior treated wood through Chicago Flameproof today!
