Where building with a light timber frame it must be built in accordance with AS 1684.1 Residential timber-framed construction.

With steel framing, as a precautionary measure, a bitumen-type coating is applied to the steel frame, in case a wall is exposed to prolonged moisture and the galvanised surface is damaged during installation in any way, as a corrosion bloom could potentially occur over time. Lime is an alkaline substance which does not corrode steel if kept dry and it also preserves timber protecting it from rot and insect attack.

While Hemp lime construction can be used with the full range of timber framing options including stud construction, post and beam, or double stud construction, wherever possible, sustainably farmed or recycled timber should be used.
