Intrastack SFS Infill

Infill walls, also known as SFS, are the non-loadbearing external walls built between floors of a primary structural frame; they are used to provide support for the cladding system.

Benefits of Steel Frame Systems

  • Quick Installation
  • ‘Dry’ Construction Process
  • Design Flexibility
  • Superior Fire Resistance
  • Exceptional Acoustic Insulation
  • Enhanced Thermal Efficiency
  • Versatile Cladding Support
  • Lightweight Construction

Non-loadbearing external wall system.  

Infill walls do not support floor loads, but are able to resist wind loads applied to the façade.  Light steel infill walls, utilising vertical C-section studs, have become the preferred choice for both steel and concrete-framed buildings, largely replacing traditional masonry or timber alternatives. 

Intrastack’s light steel infill walls (SFS) use vertical C-sections, known as studs, spanning between the floors of the primary frame and around openings. The size and spacing of C-sections are selected based on structural requirements, as well as compatibility with external façade materials and standard plasterboard widths. Wall panels can be pre-fabricated as storey-high units or assembled on-site from cut-to-length C-sections, offering flexibility for different construction scenarios.
