Since we are always innovating and adapting to our customers’ needs, we were one of the first companies to begin manufacturing CLT and offered its unique benefits to the site access and industrial matting market.  \nToday, Sterling is still America’s largest CLT manufacturer with the capacity to produce 1,000 panels a day at our plants in Lufkin, Texas and Phoenix, Illinois. In 2022 we expanded to bring our exceptional operational capacity and wealth of experience to the building construction market, with PRG 320-certified structural CLT panels available at competitive price points and timelines.  \nThis design guide was developed to give you, our community, a better understanding of our manufacturing capabilities and how the design process impacts manufacturing as part of our commitment to innovating with you. From optimal grids to spline details, we are sharing smart design solutions that will ensure we can collectively design more sustainably and bring mass timber to the masses.  \n2  \nTABLE OF CONTENTS  \nINTRODUCTION STANDARDIZATION  \nDESIGNING WITH TIMBER  \nCASE STUDIES  \n4  \n6 9  \n10  \n12  \n13  \n16  \n20  \n21  \n24  \n26  \n28  \n38  \nWhy CLT  \nProduct Dimensions Span Tables Sourcing Specifications Finishing  \nGrids Glulam  \nHybrid Structures Tolerance Machining Preferred Details  \nProject Examples  \nDesign Manual V1 3  \nINTRODUCTION  \nWHAT WE DO  \nThink of Sterling as a resource for all things mass timber.

Additionally, building with forest products typically creates fewer emissions during the harvesting/extraction, manufacturing and transportation cycle than other materials used in construction.  \nMany buildings have been completed using CLT for floors, roofs, and walls with a full mass timber system. However, it is common to use CLT floor and roof panels in combination with engineered wood framed post and beam systems or light-frame wood bearing walls as the vertical supporting structure.  \nSince roughly 75% of the carbon sequestered in a mass timber building is stored in its floor and roof slabs, increasing the adoption of CLT for horizontal plate applications can significantly reduce the construction industry's carbon footprint. Providing flexibility for the utilization of a wider range of vertical support materials while making substantial progress in sustainability.  \n300 LBS CO2E/M³ SEQUESTERED  \n500 lbs CO₂E/m³ emitted  \n5100 lbs CO₂E/m³ emitted  \nDesign Manual V1 5  \nSTANDARDIZATION  \nSTANDARDIZATION  \nDeveloped in direct relation to the established lumber supply chain, the lumber for our CLT panels is transported to our facilities by rail, ensuring consistent delivery and scalable production.
