Trees Are Climate Change, Carbon Storage Heroes

J.R.R. Tolkien, author of The Lord of the Rings, once wrote, “I longed to devise a setting in which the trees might really march to war.”

If climate change is a battle for Earth’s survival, then trees will be a vital army holding the line. When Tolkien imagined trees marching to war, he couldn’t have foreseen how relevant those words would one day be.

Trees are a bastion against climate change.

Engineering News-Record recently featured Forest Products Laboratory’s (FPL) materials research engineer, Laura Hasburgh and her expert consultation on the Ascent construction project in Milwaukee. At 25 stories, the Ascent building is making history as the soon-to-be tallest timber building in the world. And because of its unprecedented height and exposed mass timber interior, Hasburgh was contacted to lend her fire testing expertise.

The top eighteen floors of the Ascent will be framed in mass timber and the interior architectural design features exposed glued-laminated timber (glulam) framing and cross-laminated timber (CLT) slabs to showcase the natural beauty of the wood. But with these design and material choices, the Ascent’s fire safety planning needed to be carefully considered.

The team is brainstorming innovative ways to make the building material of the future—mass timber—more versatile. But in order to do that, they have to find an adhesive and a preservative, two substances that tend to be uncooperative together when used on timber, that will work concurrently for optimal bond strength and durability.
