A new building method to potentially make space architecture possible enters the fray. All Rights Reserved. Laminated beams can be used to span low- to moderate-weight roof areas and as vertical support columns or pillars. • More savings can be found in the reduced installation cost, usually 50% cheaper than installing other plate materials. Mortenson Co., in association with Urban Development Partners, is constructing Arizona's first cross-laminated timber (CLT) Class A office building in Tempe, Arizona. Cross-laminated timber (CLT) is a wood panel system that is rapidly gaining popularity in the U.S. after being widely adopted in Europe. The layered stacks are then pressed in large hydraulic or vacuum presses to form an interlocked panel. CLT (cross laminated timber) is a construction product made of solid wood, made by transverse gluing at least three layers of single-layer laminated boards [43,44]. By varying the grain direction, one advantage of laminated beams is that they are actually stronger than solid wood beams. Cross-laminated timber (CLT) is a wood panel typically consisting of three, five, or seven layers of dimension lumber-oriented at right angles to one another and then glued to form structural panels with exceptional strength, dimensional stability, and rigidity. Laminated timber is the result of joining boards to form a single structural unit. The strength, dimensional stability, and rigidity of CLT allow it to be used in mid- and high-rise buildings. At Ziegler Holztechnik GmbH cross laminated timber and glulam products are manufactured. CLT offers design flexibility and low environmental impacts for floor, roof and wall elements within innovative mid-rise and tall wood buildings. ... 25+ Beautiful & Easy DIY Christmas Cards You Can Easily Make at Home! The design provisions for CLT in Canada apply to sawn lumber panels manufactured in accordance with the ANSI/APA PRG 320 standard. The last ten years he has focused on Engineered Wood Lumber used in Heavy Timber design and Cross Laminated Timber. Cross laminated timber (CLT) panels are formed by stacking and gluing together successive perpendicular layers of wood. Although home… © Copyright Building Design & Construction. One of the best resources for clarifying the topic is the 2013 US CLT Handbook. CLT also has a high strength to weight ratio, along with exhibiting advantages for structural, fire, thermal and acoustic performance. Mass timber is not conventional so it is very hard to light, and once it is lit, it wants to put itself out (see US CLT Handbook Chapter 8, p. 2).

This process gives CLT many of its beneficial properties along with the ability to be panelized. Phenolic types such as phenol-resorcinol formaldehyde (PRF). As a California licensed Professional Engineer since 1981, he has worked in the Engineered Wood Products industry for 25 years. Katerra offers three, five, seven, and nine-ply layups with various thicknesses reaching up to 12.4 inches. Panel thicknesses usually range between 100 to 300 mm (4 to 12 in), but panels as thick as 500 mm (20 in) can be produced. A research project recently completed at FPInnovations showed that CLT panels have the potential to provide excellent fire resistance, often comparable to typical heavy construction assemblies of non-combustible construction. A two-story building on the campus of Technical University in Dresden, Germany, will demonstrate the facility of carbon-fiber reinforced concrete. A wide variety of fastener and anchor options are available depending on the required loads and application. As a result, many construction projects use beams made of laminated wood. Trees large enough to make traditional solid wood beams have become more rare and expensive. FPInnovations—in collaboration with the American Wood Council (AWC), the United States (U.S.) Forest Products Laboratory, APA, and U.S. WoodWorks—published the comprehensive guide to provide technical information for building professionals, illustrating CLT applications adapted to current codes and standards.
