Inner wall - Covered with a lining of plasterboard. External wall - Timber boarding, tiling or an outer leaf of brickwork. Most frames are pre-fabricated into storey height panels. Available in 1.2 widths to suit the spacing of the studs. Varies in thickness - depends upon material used.
Substructure depends on the ground conditions and the building load.
Timber framing has little effect on the foundation design. Preservative treated soleplate fixed onto the DPC - forms the base for the wall panels. Soleplate provides a level surface on which to fix the wall panels. Ensures that the DPC is not displaced during the erection of the shell. To ensure the correct alignment of panels an additional timber known as a head binder can be nailed to the top plate.
