SFS construction such as Metsec is a method of façade construction with ever-increasing popularity in the UK due to its versatility and speed of erection. The SFS is constructed using pre-fabricated metal members either as a continuous ribbon framing in front of the individual floor levels or installed between floors as an infill as part of the external envelope.
For window installation, the openings are created in the SFS structure which is normally clad externally with CPB (Cement Particle Board) providing a stable backing wall to which the external cladding can be attached (e.g. rainscreen or rendered insulation). The windows are normally positioned projecting out of the structural opening into the insulation and external finishes zones and in order to maintain the air and weather tightness of the building envelope, these interfaces must be appropriately sealed, usually with membranes.
