Lightweight partitioning systems are the most common type of solid partitioning used in New Zealand. Such systems have inherent environmental advantages as they are low in embodied energy and flexible for the future. However in some situations additional thermal mass can be beneficial and higher mass masonry systems may be appropriate.

One of the most common framing materials is timber. NZ Building Code NZS 3604 Timber framed buildings provides an excellent source of construction details. Timber framing should always be selected from New Zealand plantations which are certified as being sustainable managed. FSC and PEFC are two trustworthy timber certification schemes and certified timber is readily available in New Zealand. (For more information please see our timber pages.)

In dry, internal framing situations, the use of untreated timber is generally preferable environmentally. If the partition may be subject to damp then consideration should be given to using more durable timber or a low toxicity treatment system such as boron. (For more information please see our timber pages.) In all cases only treat the areas at risk. For example in low risk areas it may be sufficient to treat the base plate only.

It is often argued that steel lightweight framing is just as environmentally friendly as timber framing. This is because the steel can contain recycled materials, and is recyclable and efficient to transport. For this reason if steel framing is to be selected ensure that the material is produced locally and manufactured from recycled materials. An excellent source of steel stud detailing is available here.

New demountable partitioning systems are available which can be taken down and moved with ease. These systems will naturally reduce waste and are especially useful in commercial buildings which are prone to ongoing layout changes.
