Floor trusses are similar to roof trusses in that both utilize open web construction and connections are made using truss plates. These high quality engineered components offer longer open spans than conventional framing and can better accommodate HVAC hardware. Efficient, simple installation and proven performance make these components the wise choice.

Open web trusses are useful when project designs require greater open areas. In combination with engineered roof trusses, these structural floor members are the ideal solution for achieving the larger open spaces so popular in home designs today. Typically installed at 24” on center spacing, floor trusses offer a cost-effective solution to many design challenges.

The open web construction of engineered floor trusses also allows for simpler mechanical installations. Access to HVAC, plumbing, and electrical are hidden within the webbing and chase of the truss systems, leaving the bottom chord of the trusses clear for application of finished ceilings.

Open web floor trusses require exact measurement of the foundation to assure proper fit. Typically, each floor truss is 1” shorter than the total outside to outside bearing measurement. This gives ½” clearance at each end for sheathing thickness. Each truss is individually engineered to determine deflection and performance. The total clear span of the truss and all live and dead loads will determine the depth of the floor truss system.

Floor truss systems are placed using the supplied layout diagram and installation details. A vertical 2x4 is nailed to the ends of the trusses to stabilize the ends and support the sub-floor and wall-framing members.
