When was laminated wood first used?
When was laminated wood first used?
Glulam was first used in Europe in the early 1890s. A 1901 patent from Switzerland signaled the true beginning of glued laminated timber construction. One of the first glulam structures erected in the US was a research laboratory at the USDA Forest Products Laboratory in Madison, Wisconsin.
What does Louisiana Pacific manufacture?
wood building products
Today, LP is the world’s largest producer of OSB, and manufactures engineered wood building products. LP products are sold to builders and homeowners through building materials distributors and dealers and retail home centers.
What is the difference between LVL and LSL?
LSL is typically less expensive than other engineered wood beams. Due to its high allowable shear strength, LSL beams have the capacity for larger penetrations than other engineered wood beam options. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.
Where is laminated timber used?
Laminated timber is also commonly used for bridges, sports structures, religious buildings, and multi-use facilities such as schools, libraries and more. High strength to weight ratio: Unlike steel, laminated timber offers a high strength to weight ratio, and is considered one of the strongest construction materials.
What does OSB stand for in construction?
Oriented Strand Board is a widely used, versatile structural wood panel. Manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, OSB is an engineered wood panel that shares many of the strength and performance characteristics of plywood.
What was the first use for laminated veneer lumber?
Laminated Veneer Lumber (LVL) First used during World War II to make airplane propellers, laminated veneer lumber (LVL) has been available as a construction product since the mid-1970s.
How is laminated veneer lumber LVL made?
Laminated Veneer Lumber (LVL) is a high-strength engineered wood product used primarily for structural applications. It is comparable in strength to solid timber, concrete and steel and is manufactured by bonding together rotary peeled or sliced thin wood veneers under heat and pressure.
What does PSL stand for in lumber?
Parallel Strand Lumber
Parallel Strand Lumber (PSL) PSL is manufactured from veneers clipped into long strands laid in parallel formation and bonded together with an adhesive to form the finished structural section. The length-to-thickness ratio of the strands in PSL is around 300.
Who invented laminated veneer lumber?
The invention of laminated veneer lumber as known today can be attributed to Arthur Troutner. While glue laminated wood veneers were in use since the middle of the 19th century on a small scale for furniture and pianos, Troutner was the first to develop a laminated veneer lumber of a scale large enough to be used in construction.
What is LVL wood used for?
Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It is typically used for headers, beams, rimboard, and edge-forming material. LVL is mentioned as a subcategory of structural glued laminated timber.
Does Louisiana Pacific make LVLS?
Louisiana-Pacific may have a small engineered wood division, but that doesn’t mean it can’t provide basic LVLs needed for general building use. LVLs range from 1 1/2 inches to 3 1/2 inches wide, with depths between 3 1/2 inches to 9 1/2 inches.
When was the Willamette Valley Lumber Company founded?
1906: Willamette Valley Lumber Company is formed in Dallas, Oregon. 1954: Willamette and Santiam Lumber Company establish the Western Kraft Corporation. 1973: Western Kraft merges with Willamette.
