CLT 3xW The What, Why and When success story of Cross Laminated - PowerPoint PPT Presentation

CLT USA in the United States 2012 CLT – 3xW The What, Why and When success story of Cross Laminated Timber Technology and the future opportunities for the Southern Pine Industry Presented by MDS10 pllc, Architects and CLT USA, llc C. Crawford Murphy, Architect Michael J. DeVere, Architect

CLT USA, LLC  Cross Laminated Technologies USA, LLC (CLT USA) was formed in 2011 to develop a new industry sub-sector for cross laminated timbers (CLT) and build and operate the first manufacturing plant for CLT panels in the United States.  The company was founded by Crawford Murphy and Michael DeVere, Architects with over 71 years of combined experience in the successful completion of major construction projects throughout the USA. During the past four years they have been researching the use of CLT in Europe and Canada having made numerous trips abroad. Their knowledge of the product and its uses have made them the “go to” people for CLT in the US. They have been invited to present on the subject at numerous seminars, symposiums and lectured at colleges and universities across the US.  Principals have developed a strategy for the use of CLT in the US including structural design and usage, market development, plant design, manufacturing processes, timber supply, logistics and infrastructure.  CLT USA maintains affiliations with Southern Forest Products Association, FP Innovations and Woodworks Association.  Collaborators in several successful university grants in research and testing of the use of southern yellow pine and hardwoods in the manufacture of CLT  Voting members of the international committee that created the ANSI standards for the production and use of CLT in commercial construction in the US  They designed and built the first CLT structure in the US – Myers Memorial United Methodist Church Bell Tower in Gastonia North Carolina  CLT USA anticipates constructing the first US manufacturing plant in 2013.

Wha hat t is is Cr Cros oss s La Lami mina nated ed Tim imber? ber? Cross-Laminated Timber (CLT) panel  consists of a series of milled timber planks that are stacked, glued and laminated in perpendicular layers. The gluing takes place using ecologically friendly adhesives that are both solvent-free and formaldehyde-free. The glue is applied automatically over the whole surface and then subjected to approximately 120 pounds per square inch of pressure that provides a very high-quality level of adhesion. Material used in the fabrication of CLT  Panels are factory dried to achieve a very low moisture content (12%). Resulting panels are strong and have  favorable acoustic, thermal, fire resistant and seismic resistant characteristics. Environmentally preferable substitute for  concrete, steel, and oriented strand board Use to build energy-efficient structures  Extensively used in Canada , Europe,  Japan and now in Australia.

It is the only renewable structural building material. • A forest can absorb carbon dioxide from the atmosphere at nearly 50 pounds of carbon for each cubic foot of wood growth. • Wood has the lowest embodied energy of any mainstream building material across its lifecycle. When compared to other building materials; 1 ton of brick = 4x for 1 ton of wood. 1 ton of concrete = 5x for 1 ton of wood. 1 ton of steel = 24x for 1 ton of wood. 1 ton of aluminum = 126x for 1 ton of wood.

Southern Yellow Pine grows up to 3x  faster than other species currently being used in the production of CLT. Use of relatively low value sideboards  of a log having quality grades of #2 and #3 can be used in production. Rapid on-site erection and fewer  construction delays due to prefabricated elements. Fast and dry installation, immediate  durability. Reductions in on-site waste as wall,  floor, and roof elements are pre-cut. Reduction of on-site construction noise  by eliminating the use of most saws and hammers. Easier on-site installation of plumbing,  electrical, and HVAC duct systems.

Adv dvan anta tages ges of of Us Usin ing Cr g Cros oss s La Lami mina nated ed Tim imber ber SUPERIOR BUILDING PERFORMANCE Sound Insulation due to the inherent  acoustic protection of solid mass elements. Fire Protection due to the resistance  to spread and the structural stability of solid wood having significant thickness. Load-Bearing and seismic strength.  Successful testing and research has been conducted in Japan. Dimensional Stability. Multi-layer slab  effect, shrinking and swelling negligible. Air Tightness and Thermal Benefits.  Ambient room temperature is maintained with approximately one third the heating and cooling energy. Visible Quality Opportunities. CLT  can be sanded or planed and left exposed. Living Space Comfort. Insulation  properties moderate temperature and humidity.

Adv dvan anta tages ges of of Us Usin ing Cr g Cros oss s La Lami mina nated ed Tim imber ber LOW ENVIRONMENTAL IMPACT Low Carbon Footprint because wood products store carbon and take  little energy to produce. Carbon Neutral Buildings wood contributes to overall neutrality because  more carbon is removed from the atmosphere by the growing tree than is emitted during the process of transforming it into a product. This means wood products carry a “carbon credit” which helps offset the “carbon Debt” imposed by other building materials. Safe and Healthy Environment. Use of wood adhesives that are free of  toxins assures there is virtually no off-gassing of pollutants into the atmosphere or indoor environment. The use of CLT construction will provide a cleaner, greener, faster, and  financially beneficial alternative to standard concrete construction used today. CLT building shells are 10-50% cheaper than their concrete alternatives for the market segments considered.
