Fire-Rated Lumber
Many local building codes require the use of lumber treated with fire-retardant materials. Fire-rated lumber has all the same applications and versatility of traditional lumber, but significant advantages in terms of safety and overall cost-efficiency.
In the event of a fire, structures built with fire-rated lumber catch or burn much more slowly, providing crucial extra time for firefighting and evacuation. With results like significant potential savings of life and resources, the benefits of using fire-rated lumber cannot be overstated.
Capitol Building Supply offers dimensional fire-rated lumber and plywood products in a variety of dimensions to meet the full range of your Mid-Atlantic construction needs.
