SFS Continuous Walling
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.
Studs are designed to resist lateral wind loads plus the accumulative vertical load from the self-weight of the external walling. Therefore the framing needs to be fixed with Metsec’s slotted cleats to ensure that any vertical movement of the primary frame is not transmitted into the studs.
The SFS is supported by the primary structure at the base by either the concrete slab or ledger angles.
Continuous walling does tend to be more expensive than infill as sections need to be spliced at regular intervals and there is also the additional cost of the cleats. It does however have the benefit of being able to cantilever past the slab edge to form parapets or downstands.
