No Roof Insulation products should cover the downlights in the home. Potentially downlights covered with insulation could be a fire hazard. Drilling the downlight holes in the ceiling often ends with some of the downlights next to or under the wooden beams. The light will still be fitted in this position. The trouble comes when the Roof Insulation covers the light the heat is stored is a small area with no escape. This heat build up could cause the timber to burn. In fact, ALL DOWNLIGHTS MUST HAVE A BREATHING HOLE IN THE INSULATION.

Beware of fitting cones over the downlights as these can also be a fire hazard. The cones get hot from the heat of the downlights, and this can cause the cone to melt into the downlight wires.
