TJI Joists Vs. Plated Trusses

TJI Joists

  • Lightweight (3 lb/ft) and trimmable.

    

  • Wrapped in TimberStrand LSL rim board giving you a solid nailing surface with high shear values. Allows 1-hour separation between units and corridor.

    

  • No need for strongbacks.

    

  • Reduces costs (not just in floors but in other building materials) thanks to its shallow depth floor system design.

    

  • Does not require a fully sprinkled floor cavity (NFPA 13 Section 8.14.1.2.6)

    

  • Uses only carpet and pad to achieve Sound Transmission Class (STC) and Impact Insulation Class (IIC) ratings of 50.

Plated Trusses

  • Heavy (5-6 lb/ft) and cannot be trimmed.

    

  • No shear transfer -- requires 1x4 nailing strip on its perimeter just to prevent racking. Needs the use of draft stop or extra gypsum to achieve the 1-hour separation between units and corridors.

    

  • Strongbacks are required to help it maintain some 1-hour fire assemblies. 2x6 strongbacks are needed at 10’ on-center to reduce vibration.

    

  • Uses a deep floor system design (16” +).

    

  • Requires a fully sprinkled floor cavity unless gap is completely filled with noncombustible insulation.

    

  • Requires concrete overlay or a sound-deadening mat to achieve STC and IIC ratings of 50.
