Adhering to a New Standard of Excellence in Innovative Building Materials

CLT Construction – By Darryl Byle,

It’s a sticky problem that Forest Products Laboratory (FPL) researcher Juliet Tang in collaboration with faculty member Hyungsuk Lim and graduate students from the Department of Sustainable Bioproducts, Mississippi State University, find themselves researching.

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.

Redwood Trees—Building a Sustainable Future

Sunrise in the the Redwoods – By Stephen, Adobe Stock # 322472485

Sequoia sempervirens is an extraordinary tree.

It has been the focus of a recent conservation, sustainability, and life-cycle assessment (LCA) study by Forest Products Laboratory (FPL) researchers Richard Bergman PhD and Kamalakanta Sahoo PhD. Their study, “Environmental Impacts of Redwood Lumber: A Cradle-to-Gate Assessment,” measured environmental performance ofthe coastal redwood through LCA by tracking material flows, energy consumption, and emissions from forest management through the lumber manufacturing process. Bergman and his team used SimaPro modeling software to estimate raw material consumption, environmental outputs, and associated impacts along its supply chain.

Like the public, concerns about protecting these trees and keeping forests as forests are also at the forefront of FPL researchers’ minds.

110 Years of FPL: Early Fire Retardant Treatments

In celebration of 110 years of research at the Forest Products Laboratory (FPL), we are revisiting blog posts that detail some of our most interesting historic people, places, and projects. Enjoy!

In the early days of developing fire-retardant treatments, researchers at the Forest Products Laboratory (FPL) investigated about 130 treatments. Combinations of chemicals were used to obtain the best performance for both fire resistance and other performance properties, such as corrosion, leaching, gluing, finishing, and cost.

110 Years of FPL: Laminated Wood Products

In celebration of 110 years of research at the Forest Products Laboratory (FPL), we are revisiting blog posts that detail some of our most interesting historic people, places, and projects. Enjoy!

FPL’s pioneering work on the engineering design of glued-laminated construction helped launch the laminating industry in the United States. Much of the research on laminated wood originated at the time of the first World War when the Bureau of Aircraft Production approached FPL with a need for lightweight airplane wings.

Remembering Former FPL Director Robert Youngs

Robert L. Youngs, director of the Forest Products Laboratory (FPL) from 1975-1985, passed away Saturday, April 25, 2020 in Blacksburg, Virginia at the age of 96.

Bob first heard of the Lab when he was studying wood technology as an undergrad at the College of Forestry at Syracuse. FPL’s famed Wood Handbook was one of his textbooks. Later, as a graduate student at the University of Michigan, Bob’s advisor had previously worked at FPL, and Bob recalled he “was very effusive in his praise of the Laboratory as a place to work.”

Upon graduation, Bob wrote to FPL inquiring about work, but there were no positions available. One year later, he inquired again and his timing was right. FPL had just received some extra funding related to the Korean War, and Bob was hired on to work in wood drying. He continued in this line of research, even studying it as he earned his Ph.D. from Yale, and eventually helped developed the original Dry Kiln Operator’s Manual, one of the Lab’s most popular publications.
