Light steel framing

Also See:


Roofs supported by LSF constructions shall be designed to support the roof coverings and transfer loads safely and without undue movement.

Connections between LSF walls and timber or LSF pitched roofs require careful consideration in the design.

LSF pitched or flat roofs should only be used in warm-roof or hybrid construction, i.e. with insulation over rafters (or joists in flat roofs).

Additional information can be found in the following SCI publications:

  • „‘Building design using cold formed steel sections: construction detailing and practice’ (P165)
  • „‘LSF in residential construction’ (P402)
  • „‘Modular construction using light steel framing: design of residential buildings’ (P302).

Condensation risk should be considered in accordance with BS 5250.
