Modular construction, using timber as a key element, is a credible solution to fast and sustainable house building. However, Metsä Wood believes that more needs to be done in terms of sharing knowledge and innovation in wood construction to further advance the use of this material in mainstream construction.
In order to help facilitate this process, Metsä Wood has launched its Open Source Wood initiative at www.opensourcewood.com. Metsä Wood’s Executive Vice President, Esa Kaikkonen, explains: “Not enough knowledge about modular wood design and building is shared, so wood construction remains niche. There is plenty of innovation but it is difficult to find, so Open Source Wood is our solution. We believe that with open collaboration the industry can achieve significant growth.”
The potential of wood is undeniable and today, offsite construction has major aspirations. Prefabricated wood elements enable fast, efficient and environmentally sound design without reducing quality. Reports on the benefits of such a lean approach are compelling: In a study of companies that have applied lean construction methods, 84% report higher quality in construction and 80% experienced greater customer satisfaction.
The report also highlights that almost 70% of projects that used prefabricated elements had shorter schedules and 65% had decreased budgets. Timber prefab construction also reduces other inconveniences such as the constant unloading of building materials, as well as the amount of on-site waste and the need to transport it.
Innovation in the house building sector is key, and offsite timber construction could be key in achieving the high volume of housing required. Using new and innovative products like Metsä Wood’s Kerto LVL (Laminated Veneer Lumber), homes constructed offsite can be turned around in a matter of weeks. Modern engineered wood products can be used for a variety of housing projects ranging from terraced and detached homes through to apartment blocks several stories high.

American Wood Council released the following statement regarding the U.S. House of Representative’s passage of the Resilient Federal Forests Act of 2017 (H.R. 2936). The bill (H.R. 2936) includes the research title of the Timber Innovation Act (H.R. 1380/S. 538), which would establish a performance driven research and development program for advancing the use of innovative wood products in building construction.
“The United States has an opportunity to help bring an innovative and sustainable technology to our nation’s construction industry,” said AWC president and CEO Robert Glowinski.
“This bill includes language directing the technical assistance and research components already in place at the U.S. Department of Agriculture to facilitate the use of these innovative wood products into mainstream construction through research and development, education, and technical assistance. Supporting mass timber construction is a win-win because it would introduce new carbon-neutral building materials to our urban areas, as well as job creation in rural areas.”
Congressmen Bruce Westerman (R-AR), Mike Conaway (R-TX) and Mike Thompson D-Calif.) helped sponsor and advance the bill.

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.

A building materials supplier is investing $10 million dollars to build a new manufacturing facility in Bowling Green.
Governor Matt Bevin said Thursday that Carter Lumber Company will create 50 jobs for the region and operate under its Kight Home Center division. The operation will produce roof and floor trusses, wall panels and other wood products.
Construction of the 70,000 square-foot facility is anticipated to begin later this year and would open in late 2018 or early 2019.
Bowling Green Mayor Bruce Wilkerson said Carter Lumber is welcome to the city’s business community that he says is expected to grow over the next several years.

The U.S. Forest Service is working to build markets for innovative forest products. One of these products, cross-laminated timber, also known as CLT, offers an opportunity for raising tall buildings with wood, opening up a completely new market for wood products.
And there’s tremendous opportunity to increase the market share for wood-based construction. Because of its high strength, CLT is an advantageous alternative to traditional building materials such as concrete, masonry, and steel. Because CLT panels resist compression, they are well-suited for building multistory structures, especially mid-rise buildings. Made from layers of dried lumber boards, stacked in alternating direction at 90-degree angles, glued and pressed to form solid panels, CLT has exceptional strength and stability and can be used as walls, roofs, and floors.
Additionally, CLT is highly resilient to fire, earthquakes, and even explosions. In fact in a recent series of live blast tests, CLT passed with flying colors. An examination of the results showed that the CLT structures suffered less degradation than expected and might outlast concrete and steel.
In terms of fire, CLT is like using a large log to start a campfire—it doesn’t ignite easily. And when it does burn, a char layer forms on the outside, protecting the inside and allowing the wood panel to maintain its structural integrity during fire scenarios.
Researchers have conducted extensive seismic testing on CLT and found that the panels perform exceptionally well in multi-story applications. When a seven-story CLT building was tested on the world’s largest shake table in Japan, it survived 14 consecutive earthquake simulations with almost no damage.
