Description
This report contains the results of surveys on the materials used in new non-residential buildings. The aim is to provide information useful to building material manufacturers, retailers/wholesalers, builders, designers, researchers and government officials.
In general, many of the market shares of materials have been relatively steady over the years surveyed.
In 2019, partition wall framing market shares became relatively even, with steel, timber and ‘other’ ranging from 30–39%. Steel remains the primary material for main structural framing. Steel and other metals are also the most common roof and wall cladding.
Timber remains the most common material for infill framing – the framing between the main structural elements – closely followed by steel.
For insulation, fibreglass is no longer as dominant, with the ‘polyester and other’ category now ahead for wall insulation. Polystyrene is still the most common insulation
in insulated floors.
Scope
Using the data collected, representative estimates of the incidence and proportions of many different materials can be made.
The components analysed are:
- roof claddings
- wall claddings
- main structure
- partition wall framing
- wall infill framing
- wall insulation
- ceiling insulation
- floor insulation
