Description:

The advent of the light steel frame building (LSFB) method has been one of the most exciting developments in the international building industry in recent decades. Used increasingly across the USA, Australia and New Zealand, it was introduced to South Africa only relatively recently. The local mainstream building market has been cautious in accepting LSFB, yet the building method’s manifold advantages – substantially faster construction time, energy and cost efficiency, and significant environmental benefits – are grabbing the attention of a growing number of industry players.

“Time can also be saved when using LSFB by different disciplines work in parallel. For example, LSFB window apertures can be agreed upfront with the glass and aluminium contractor, even before the light steel frame walling is installed, since the framing system is extremely accurate,” Barnard says.

Light steel joists were used for the roof structure, and installed at 1,2m spacings. Purlins consisting of cold-formed top hat sections, made using high strength galvanised steel sheet, are fixed to the roof beams using self drilling screws. The roof sheeting – Arcelor Mittal’s Chromadek was used for this purpose – was then fixed to the purlins, again using self-drilling screws. As with the all the light-gauge steel used in the frames, the screws have to comply with stringent corrosion resistance standards to ensure the long, maintenance-free life of the building.

“Insulation in the ceiling under the roof is of paramount importance for a well-insulated building – to prevent losing heat in winter, and gaining heat in summer. We used 135mm-thick glasswool insulation, as required by the light steel frame building standard (SANS 517),” Barnard explains.

For the ceiling under the floor of the second storey, the team used 15mm-thick fire resistant gypsum board, to meet the fire rating requirements. They put 50mm-thick pink fiberglass insulation in the ceiling, for acoustic insulation.

Both the walls and the ceilings were skimmed with a thin layer of gypsum cement – providing a perfectly smooth surface for painting.
