Timber or Steel Framed Walls
In framed wall constructions of timber or steel the insulation is fitted between the studs, combining the structure and thermal insulation into the same plane. The internal face of the wall is lined with plasterboard, whilst the external face can be finished with a single leaf of brick, tile hanging, boarding or a render system (see Figure 54). Where necessary the thermal performance of the wall can be improved by installing a further layer of insulation across the face of the studs: that will also reduce the effects of thermal bridging.
The use of framed wall construction has become increasingly common, most notably in Scotland and Ireland where the required U-values for walls are already 0.30W/m2K and below.
