The purpose of this document is to give guidance to approved contractors and suppliers who are engaged in the fire stopping of fire rated structures using the Astro LUMI Canopy.

All service holes through floors,ceilings and compartment walls must be fire stopped to prevent the passage of fire, smoke and hot gases.

The key points for passive fire protection products are :-

  • Prevent the spread of fire, smoke and hot gases through a building by containing it in the compartment of origin.
  • Maintain the integrity of escape routes from a building.
  • Reduce loss or damage to property from the effect of fire and smoke.
  • Maintain pressure differential between compartments and ventilation channels.


Luminaire canopies are designed to specifically stop the passage of smoke and fire through a fire rated ceiling,where recessed downlights are fitted.

Tests have shown that, without the canopy in place, fire and smoke would penetrate through the recessed light fitting in seconds spreading into the void or room above endangering both lives and property.

The Astro Lumi Canopy will provide 60 minutes protection by completely containing the fire and smoke within the cover,whilst at the same time allowing the heat from the light fitting to dissipate through the cover
