Application

Can be used with the majority of external finishes, across most applications. It is compatible with reinforced concrete and hot rolled steel frames, and traditional, pre-cast concrete and tensioned slab designs. It suits infill, oversail and loadbearing systems:


Infill systems:

Infill between structural slabs and steelwork. Normally offset 20 mm from the edge of the structure.


Oversail systems:

Installed outside the line of the structural frame using specially designed support cleats and brackets. Particularly suitable to projects where the façade treatment needs to have movement joints reduced or removed or where internal floor area needs to be maximised.


Multi-storey loadbearing:

Most commonly used for extensions of old or existing buildings.

Description

The cold rolled SFS offers a structurally robust and dimensionally stable warm spaced wall construction that can be used with most external finishes.


This component supply structural stud and track system, is available to suit infill, oversail and loadbearing systems that provide early weather protection capability to the building.


Features and benefits:

  • Lighter than blockwork which reduces foundation mass and costs.
  • High value commodity.
  • Can be installed in any weather conditions.
  • Easily adapted to site.
  • 100% recyclable and will lose none of its structural strength during the recycling process.
  • Bespoke solutions can be achieved with the flexibility of the products. Consult manufacturer for more information.
