Prefab Building Applications

There are two main types of prefabrication, namely volumetric (often referred to as 'modular') and panellised. Both of these types of construction can be achieved in timber, steel and concrete, and can also be mixed within the same scheme.

Steel systems for housing are usually light gauge galvanised steel. Timber systems can be relatively traditional in that the construction mirrors what might be produced on site using components such as timber studs and sheathing. It can make use of timber Ibeams which give longer spans with a relatively lightweight beam. A third option is Structural Insulated Panel systems, which use fewer studs and rely in part on the bond between rigid insulation core and outer sheathing materials for strength.

One factor that differentiates all prefabricated timber systems from what might be termed traditional timber frame is the amount of work undertaken in the factory.

While there does not appear to be a formal definition separating the two, the prefabricated panel might include any insulation material, the sheathing boards and possibly some services.
