Light steel framing is extensively used due to its
good thermal and structural behaviour. Heat
loss reduction and thermal comfort have been
the main driving forces defining the design of
these frames. With this form of construction it is
important that some insulation is placed inside
or outside the steel frame to provide a thermal
break and avoid condensation.
There are two major construction types:
Warm frame construction where all the
insulation is outside the steel frame.
One disadvantage of this technique is the loss
of any possible insulation benefit by not utilising
the space between the steel frame studs.
Hybrid construction, where insulation is included
both inside or outside the steel structure and in
between the steel components (a minimum of
33% of the thermal resistance should be
provided outside the steel frame.) With this form
of construction a condensation risk analysis
(in accordance with BS 5250) should be
provided by the system manufacturer to ensure
there is no risk of interstitial condensation.
A vapour control layer should be installed on
the warm side of the internal insulation layer.
This method is becoming increasingly popular
both in standard 2-3 storey housing and high
rise apartments alike.
Steel frame construction has many of the
attributes of timber frame construction:
• Off-site prefabrication delivers a quality
• Quick erection of the structural frame and
early creation of a dry envelope, thus
removing the external finish from the critical
path and enabling an early start on the
internal fit out
• Wet weather does not interrupt erection process
• Lightweight structure reduces load on
foundations, especially important on
brownfield sites and rooftop extensions
In addition, steel has a higher strength to
weight ratio than timber, enabling more flexibility
in design and clear floor spans over 7m.
Although steel does not have the sustainability
credentials of timber, it is fully recyclable and
steel manufactured in the UK usually contains
approximately 20% recycled content.
Light steel framed structures can be used for
buildings up to six storeys high, although British
Board of Agrément certificates limit some
systems to four storeys. A steel frame system is
usually based on factory made or site
assembled panels and sub-assemblies forming
the structural steel framework of a building or
the light steel infill system within a structural
concrete or steel framed building.
Structural steel framed external walls are
usually manufactured from 75mm or 150mm
wide loadbearing C studs. The use of factory
manufactured components guarantees
dimensional accuracy and all structural
steelwork should be fabricated from
galvanised steel to BS EN 10326 : 2009
with a Z 275 coating.
