The most common application for SFS is infill walling. In this scenario the SFS is constructed from the floor to soffit of the primary structural frame to ‘infill’ the external wall zone. This option is typically the most economical solution and allows the SFS to be installed from the inside of the building.
The studs are designed to resist lateral wind loads only, using SFS patented slotted head track to allow the primary structure to deflect without applying any vertical load into the studs.Where it is necessary to use sections with a higher capacity, single sections can be fixed together to form compound sections. This can be done for jamb, cill and lintel sections.
Parapets and downstands can readily be formed with SFS using posts, which can be incorporated within the framing. These posts can also be used to break up the span of wide openings and also allow the formation of ribbon windows.Continuous walling is where the SFS is designed so that it ‘oversails’ the edge of the primary structure. This method is often used when a design team wants to maximise the amount of internal floor area or if they are using a cladding which cannot accommodate horizontal deflection joints at each floor level. Continuous walling is typically constructed from the outside of the building.
