In any building, a ceiling helps slow the spread of fire. The ceiling will have a fire rating depending on how well it slows the spread of fire. If you install a Recessed downlight into a ceiling, chances are you are reducing that fire rating. Fire rated downlights have an important role in fire safety, as they effectively block the hole cut into the ceiling. On each down-lighter they have an in tumescent pad, which will expand when it reaches a certain temperature, and ultimately slow the spread of fire. Different fire rated downlights have different fire rated times, varying from 30 to 90 minutes.
Without fire rated downlights, it can mean that your ceiling collapses within just a few minutes compared to giving you extra time to get out to safety.
