Installing Insulation Around Recessed Lighting
Incandescent lights generate a lot of heat and can cause fires if they are close to flammable materials, so knowing insulate around your recessed lights is important in preventing fire hazards. The method used depends on the type of lamps you have installed. Read on to learn what to look for when insulating and do the job correctly.

1. Verify that the an "IC" designation on them. "IC" means "insulation contact," meaning that insulation can touch the light without danger. If the lights have "IC" labels, you may insulate around them. If the lights do not have this designation, use them in a location that does not require insulation. If you wish to use non-IC lights with insulation, see Step 3.
2. Whether the light is IC or not, read the printing on the electrical cable connected to the light to verify that it is rated for temperatures to 75 degrees C. If the wiring was installed prior to 1986, it is only rated to 60 degrees C and must be replaced with new cable that can withstand the additional heat from the lamp.
3. Insulation must be at least 3 inches away from non-IC lamps. Put a piece of wood or sheet metal between the ceiling joists on either side of the lamp to prevent insulation from touching the lamp. If you do not wish the lamps to remain uninsulated, replace them with IC-rated lamps.
4. Get your work approved by the building inspector.
