Traditional Stick Framing – Carpenters take 2x6, 2x8, 2x10 and 2x12 sticks of lumber to the job site. They hand cut and fit this lumber together into a roof or floor system. Timber Frame – Craftsmen assemble timbers, joinery and braces together to form a self- supporting skeleton structure. Engineered Wood Products – I-Joists, Glulam, and LVL (laminated veneer lumber) wood products are shipped to the jobsite, cut to fit, and made into beams for the floor system, or into ridge beams and sloping joists for the roof system. Truss Systems – in two primary forms: • Metal Plate Connected Wood Trusses – Engineered trusses are designed and delivered to the jobsite with a truss placement plan. Trusses are quickly erected and braced onsite. • Steel Trusses – Light gauge steel trusses are designed and delivered to the jobsite with a truss placement plan. Trusses are lightweight, able to be quickly erected and braced onsite.
