for the proper nailing and gluing of subfloor materials.
By prouiding such a wide surface, the Trimjoist
allows the builder to use sub-floor framing tolerances that will prevent squeaks. The wide surface also allows for application of sufficient glue
to make the Trimjoist and the subfloor truly act as a unified system.
The Trimjoist addresses product consistency and product quality from three key perspectives:
The Trimjoist was initially designed using the most capable structural engineers and computer software
systems available from both inside and outside the forest product industry. This includes the PPSA system from Purdue University as well as Rasna finite element softeare from Parametric Technology.
All raw material components are structurally rated
by various independent agencies such as the Truss Plate Institute, Southern Pine Inspection Bureau, American Plywood Association, American Society for Testing and Materials, and of course ANSI. In
fact, all Trimjoist floor trusses now conform to the new ANSI/TPI-2002 standard. In addition, all lumber components of the Trimjoist are subject to a strict "cull" process where before entering into the production process.
In addition to the rigorous testing performed on prototype units during the development phase of the Trimjoist, all production runs are subject to periodic, ramdom tests. These tests are conducted to the standards of the Trust Plate Institute Test Truss Specification. No other production floor truss is sibjected to such ongoing scrutiny and improvement.
The Trimjoist design allows for the utilization of lumber from plantation-grown trees, thus sparing the "old-growth" forest that are necessary to produce all traditional wide-board joist. In addition, our engineered strength allows for longer spans and greater on-center spacing. This not only reduces construction cost , but can reduce the board footage of wood fiber required by up to 12% over traditional joists.By design, approximatrly 40% of the Trimjoist material content is from recycled sources. In addition, our manufacturing process recovers over 97% of its generated waste.
The Trimjoist is produced in stock lengths that range from 4' to 30', in standard 2-fppt increments. Because each joist has 12-inches of trim at each end, a continuous range of spans is possible. Complex angled walls? No problem for the Trimjoist.
The open web design of the Trimjoist
allows for the utilization of that valuable
floor cavity space. It's now practical for
duct work,wiring,and plumbing to be
contained within this cavity.This eliminates
unsightly and expensive furring. Free access
to the floor cavity requires no cutting or notching
that can severely impair the structural integrity
of other joist products of inferior design.
PUT SIMPLY, THE TRIMJOIST IS THE SUPERIOR PRODUCT FOR YOUR FLOOR JOIST APPLICATIONS !
