Technology Validation Guide
LSF Systems Overview The type of certification selected for LSF technology is determined by the type of system, the sector in which it is being used and the design parameters of the structures. Validation is provided by a variety of organisations, who carry out an assessment of the build system. There are numerous types of providers, and whilst the majority relevant to LSF construction are included here, it should be noted that there may be other providers who offer an acceptable level of validation. Certification is underpinned by supporting data which validates the system, the level of data is driven by the type of system used and complexity thereof. A high level overview of the certifications, warranties etc. in relation to the use of light gauge steel frame is given here in relation to the three main system types outlined below;
SFS Infill/Oversail Systems SFS Infill/Oversail systems generally require a lower level of certification and therefore validation through testing is less onerous as these are typically non-loadbearing elements of structure. That said these systems can benefit from achieving the majority of available certifications..
Panelised Systems Walls in panelised systems can be either open or closed frame technology. In closed walls, this is a full through wall system which will include either the external or internal linings, or potentially both. The prospective certifications for both systems are the same, however the level of fire testing for validation purposes is higher for a closed panel system. Where the external façade is included as part of the system other areas of assessment such as weathertightness and loads imposed by the façade need to be taken into account. In panelised systems walls and floors are generally tested as individual, standalone elements.
Ayrshire Metals
Intelligent Steel
Modular Systems Certifications, testing etc. for modular build systems are similar to panelised systems and the same principles can be used. However, as the wall and floor/roof elements are formed as one structure in addition to separate wall and floor fire tests there are opportunities for fire testing of the whole module. EOS
