Normal spacing is at 450mm centers for external walls and 600mm for internal walls unless specified otherwise for structural reasons.
Can a single top plate be used for roof trusses?
A single top plate does not have the strength to carry major loads, such as roof trusses or upper floor beams so these should be fixed directly above the studs. To increase the strength, if required, a second timber can be added during erection to make a double top plate.

What is the best treatment for termites?
Timber requires treatment to limit termite attack and rot. Options (Ecospecifier 2012) include the following: 1 Light organic solvent particles (LOSP) treatments offer low toxicity preservatives, fungicides and insecticides. Protection levels range from H1 (lowest protection) to H3 (exposed external applications). Unsuitable for in-ground applications. 2 Boron and fluorine products are available as paints and provide largely benign preservative, fungicide and insecticide protection for H1–H4 applications. Products are water-soluble and require retreatment at regular intervals. 3 Copper azole is a highly effective alternative preservative, fungicide and insecticide suitable for H1–H4 (in-ground) applications. It contains no high toxicity arsenic or chromium compounds and can be burnt and mulched. 4 CCA (copper chrome arsenate) solution is not recommended. It emits highly toxic smoke if burned and cannot be mulched. Any quantities, including shavings and offcuts, must be disposed of as landfill. CCA is effectively prohibited in Japan and some European countries and being phased out in the US. Contact with CCA-treated timber may be toxic to young children (Environmental Working Group 2001). 5 Glues and solvents used in engineered timber products often contain formaldehyde — a known carcinogen — and volatile organic compounds (VOCs) with known adverse implications for human health. Some products now use low formaldehyde and VOC glues (see The healthy home).

What is MRTFC construction?
Multi-residential timber framed construction (MRTFC) uses fire and sound-rated timber framed wall and floor systems to provide vertical and horizontal separation between dwellings. It is an innovative use of lightweight framing techniques to deliver cost effective, low mass housing solutions that are highly appropriate for most climates and likely to be better able to respond to climate change (see Thermal mass).
Why is bulk insulation not compressed?
Bulk insulation performance is reduced if it is compressed because it is the trapped air that insulates, not the material .
What are the two methods of dealing with termites?
The two principal methods of dealing with the threat of termites are chemical and physical.

How does sound travel through a building?
Sound travels via floors, walls and ceilings in lightweight framed buildings, by both direct path and reflection , and each of these elements requires effective sound treatment to ensure acceptable outcomes. This means selecting components with the appropriate sound insulation rating as well as framing details that minimise transmission.
What is lightweight framed home?
Lightweight framed homes can range in appearance from the ultra-modern to the traditional weatherboard bungalow. With the enormous variety of non-structural claddings, linings and finishes available (e.g. reconstituted forestry waste, fibre cement sheet or siding, plywood, weatherboard, brick veneer, or metal) lightweight framed construction can be used to create almost any desired architectural form or finish (see Cladding).
