Timber Structures Worldwide Show Potential Of Wood Construction

by | Aug 14, 2017 | News

Roofs made from wood are one or the rarest roof types to find around these days, as concrete slab and shingles take over, according to Choice Solutions Roofing and Exteriors Co. In Oklahoma City.

Wood is not seen as strong as some other materials when it comes to construction, but in general well-maintained roofs made of wood can have a lifespan that ranges from 30 to 50 years. Having a wooden structure on top of a house has several good qualities, and it can look great. Here are some examples of wooden structures which are not the average roof that will provide an idea of how unique and marvelous structure topped off with wood can become.

The Centre Pompidou Metz has a hexagonal pattern of a load-bearing timber roof structure which is visible at night through its transparent covering membrane. It is interesting to know that the inspiration of the roof comes from a woven Chinese hat. Before this one-of-a-kind structure was created, it was studied from every angle to ensure that it would withhold heavy weather conditions. This woven like structure roof is made out of wooden beams, spaced 2.90 meters apart, forming a hexagon pattern that is 90 meters wide.

The timber used is glue laminated which enables the different lengths of the beams and makes them more resistant. It is without a doubt an astounding structure due to its complex curves and counter curves and therefore it is one of the most challenging and largest structure built up to date.

The mesh can allow the roof to expand 40 meters, made from protective fabric which consists of fiberglass and Teflon, forming a membrane over the wooden structure. This layer helps the inside temperature to stay natural. This building was created for displaying art and the goal behind the innovative structure was to draw tourism to Metz, France.

Timber Construction Has Mill Machinery Rolling

by | Jun 13, 2017 | News

Timber construction is opening a new market that has been keeping lumber and milling machinery busy at a growing number of wood products companies, including Montreal’s Nordic Structures, Sauter Timber in Rockwood, Tennessee, SmartLam, in Columbia Falls, Montana, and D.R. Johnson, in Portland, Oregon.

Oregon-based D.R. Johnson Wood Innovations, a subsidiary of D.R. Johnson, specializes in the manufacture of cross-laminated timber, or CLT, and glue-laminated beams from Douglas fir and Alaskan yellow cedar. D.R. Johnson Wood was the first U.S. company to receive APA/ANSI certification to manufacture structural CLT panels – and CEO Valerie Johnson plans to help grow the U.S. market.

D.R. Johnson has received the first U.S. certification to manufacture cross-laminated timbers (CLT) under a new standard approved last year by the American National Standards Institute. D.R. Johnson is one of only three North American companies certified by the Engineered Wood Association to construct CLT for use in buildings.

Johnson’s company employs 125 at a traditional sawmill and laminating plant, which was recently expanded by 13,000 square feet for increased CLT production. They’re currently fielding calls from hopeful builders, and manufacturing samples to be tested for fire safety and structural quality. One recent new wood construction project is a 14-story wooden apartment tower being built in Portland, Oregon.

Vaagen Timbers Gets Into CLT

Vaagen Timbers Gets Into CLT

 

Sawmillers have formed Vaagen Timbers, which will construct a mass timber facility in Colville, Wash. The new business will produce cross-laminated timber (CLT) and glue laminated beams (glulam).

Vaagen Timbers is partnering with Vaagen Bros. Lumber, Inc. for the supply of lumber to the new facility, which will be adjacent the Vaagen Bros. Lumber sawmill in Colville.

“Although the entities will be operated separately, this connection will add value to both businesses,” comments Russ Vaagen. “This will allow Vaagen Bros. and Vaagen Timbers to tell the small log story from the forest to better buildings.”

The state-of-the-art facility will be designed to produce multiple sizes of straight glulam beams up to 60 ft. long. CLT production will be up to 12 in. thick, 4 ft. wide, and 60 ft. long. Operations are scheduled to begin in 2018.

Production capacity numbers are still being tested, but forecasted capacity on two shifts for two press lines will consume approximately 50MMBF per year. Once Vaagen Timbers develops market demand, plans for a second 8 ft. press will provide a more diversified product offering.

“This is exciting for all involved including the forest, the community, and the future of eco-friendly buildings in North America,” Vaagen adds.

Bert and Bud Vaagen founded Vaagen Brothers Lumber in the early 1950s and the business has not only been a sawmilling mainstay in the Northwest since then, but is recognized as one of the leaders of the industry. Current President Duane Vaagen was Timber Processing’s Man of the Year in 1989.

D.R. Johnson Ready To Serve New Wood Building Market

by | Oct 7, 2016 | News

If the vast potential of timber construction isn’t obvious, a new exhibit at Washington D.C.’s National Building Museum aims to clear things up. Running through May 2017, the USDA-sponsored Timber City is drawing attention to the recent boom in a worldwide movement toward timber construction.

It’s opening up a new market that has been turning the mills at a growing number of wood products companies, including Montreal’s Nordic Structures, Sauter Timber in Rockwood, Tennessee, and D.R. Johnson.

Oregon-based D.R. Johnson Wood Innovations, a subsidiary of D.R. Johnson, specializes in the manufacture of cross-laminated timber (CLT) and glue-laminated beams from Douglas fir and Alaskan yellow cedar. They’re the first U.S. company to receive APA/ANSI certification to manufacture structural CLT panels – and they hope to help grow the U.S. market.

D.R. Johnson is one of only three North American companies certified by the Engineered Wood Association to construct CLT for use in buildings. The company employs 125 at a traditional sawmill and laminating plant, which was recently expanded by 13,000 square feet for increased CLT production. They’re currently fielding calls from hopeful builders, and manufacturing samples to be tested for fire safety and structural quality.

D.R. Johnson says the system for constructing CLT involves assembling prefabricated parts, speeding construction, and paring labor costs. The company partnered with wood processor manufacturer USNR to build a custom panel press for CLT.
