It's supple enough to sway in windstorms without snapping, yet strong enough to support its weight—up to 160 metric tons. Kilogram for kilogram, a wooden beam made from this fir is 3.5 times stronger than steel. A single tree can store half its weight in carbon and can replace itself, given enough time. Its luminous, patterned wood can be sculpted into virtually any shape.

For more than 15 years, NFPA’s wildfire safety recommendations have been shaped by this fire science and because of it, is able to provide actionable guidance for homeowners to help them prepare homes/home landscapes to resist wildfire.
