Fire Rated Control Joints
The Building Code of Australia requires the gaps between building elements to have the same fire rating as the required building element. These gaps are known as fire rated control joints and are nominated as an essential safety measure by the building surveyor/ building certifier in a building permit/ building approval.
Building Code of Australia
Part G3 Protection of Openings, clause C3.16 Construction joints, requires fire rated control joints between building elements required to have a fire resistance level must be protected in a manner that complies with an identical prototype tested under AS1530.4-2000 Methods for fire tests on building materials, components and structures – Fire resistant tests of elements of construction.
The following illustration depicts maintaining the integrity of a fire-resisting wall through fire rated control joints.
