Substrate is the surface to which a material or product is applied.

During recent decades, the emphasis in structural design has been moving from permissible stress design to limit state design since the latter approach makes possible rigorously designed, yet economical, structures by considering relevant modes of failure directly.

Atmospheric corrosivity categories are a standardised rating of the corrosivity of the atmosphere in relation to the corrosion rate of certain metals.

The collection, storage and use of rainwater has potential for considerable reduction in the requirement for potable (mains) water supply. This TECHnote suggests ways that a NATSPEC based specification can be used to specify a rainwater harvesting system.

This TECHnote suggests some ways to use NATSPEC worksections to specify Building Management Systems (BMS) and automatic controls.

Compliance with the Deemed-to-Satisfy energy efficiency provisions of the NCC can be achieved using thermal modeling software and load limits for the climate zone specified in the ABCB standard NatHERS heating and cooling load limits. The NatHERS compliance pathway requires a building to achieve a minimum star rating and satisfy corresponding heating and cooling load limits.

This TECHnote includes information useful in satisfying the NCC energy efficiency provisions for Class1 buildings and Class 10a buildings.

This TECHnote summarises typical sealant types used for different applications in construction.

Pipe supports are required in various applications, many of which are governed by Australian and other standards.

This TECHnote provides guidance on the National Construction Code (NCC) classification of the fire behaviour of building materials and assemblies. Classification is generally based on the level of risk associated with different classes of buildings and how they will be used.
