Fire rated downlights within residential or commercial installations help reduce the spread of fire through different zones of the property. Initially when a hole is cut through the ceiling space, this allows fire to track through ceilings and spread through the ceiling cavities.
For example; A multi-level living space may have 3 residents living above each other. If a fire starts in the bottom level it can quickly spread through ceiling spaces and move into the other spaces. The purpose of fire rated downlights is to reduce the risk of this happening.
The fire rated downlight effectively blocks the hole in the ceiling using an intumescent material that expands when exposed to heat resulting in the fire spread being significantly reduced.
