Blocking Panels

Blocking Panels- are pieces of TJI® Joists or solid sections of Structural Composite Lumber (SCL) that fit perpendicular between the joists. Blocking panels transfer both vertical and lateral loads through the floor.


Five primary uses of blocking are:

  • To transfer load from stacking bearing walls above to bearings below
  • To transfer diaphragm or shear wall loads through the floor into a wall or foundation below
  • Provide lateral support for joists at bearing locations including cantilevers, multi-span conditions, and ends of joists
  • To prevent rollover during installation of joists that lap or butt over a bearing
  • Fire draft stop
