Sandy Springs, Ga., an Atlanta suburb, amended its building code to prevent buildings taller than three stories and larger than 100,000 sf from being wood-framed.
Supporters of the change cited safety, durability, and longevity as concerns regarding wood-framed construction. Georgia Forestry Association and American Wood Council officials countered that wood is a more sustainable material and said the code change would harm the wood industry.
The use of cross-laminated timber (CLT) for framing high rises is growing, particularly in Europe, where wood-framed buildings as tall as 80 stories have been proposed. Firefighting professionals around the U.S. have expressed concern about the fire resistance of wood-framed tall buildings.
CLT manufacturers say the material is just as safe as steel and concrete, and can be installed more rapidly.
