Can you remove foil insulation from a light fixture?
Removing the foil insulation may cause the fixture to operate in an unsafe manner. There may, however, be a need to remove parts of the foil insulation around screw holes or edges to make the base fit.

Do LED lights need thermal protection?
Despite an efficiency advantage over other light sources, LEDs can still suffer reliability issues if all parts of the lighting system, including the driver, aren't properly protected from over-temperature situations, says Steve Roberts.
Do LED can lights get hot?
Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer. The heat from the lighting will also warm your surrounding environment but in comparison to old incandescent lighting, this ambient heat is greatly reduced when using LED lighting.
What goes first insulation or electrical?
It is important that wiring is done before insulation is put into place in new construction. Holes need to be drilled into the frame and wires run throughout the walls. Trying to do this kind of work around insulation would provide needless obstacles for the electricians to work around.
Does electrical wiring go behind insulation?

Why are wires insulated?
Cable and wire insulation prevents the wire's current from coming into contact with other conductors, it preserves the wire material against environmental threats and resists electrical leakage. There are three major categories of wire insulation, each with a variety of styles.
What is IC rated light?
IC-rated lights (insulation contact lights) are truly the only lights that are designed to be used in contact or close proximity to insulation in your walls or ceilings. For products that are not IC-rated, it’s important to know how to treat the downlights before installing insulation.
What is recessed lighting?
Shutterstock. By: Emily Fazio. Downlights, also commonly known as recessed lights, are an undeniably affordable and popular way of adding lighting to a room. Installed during both new construction and home remodeling projects, downlights offer many advantages to spatially sensitive homeowners by permitting extra lighting ...
Can downlights be out of sight?
However, trouble with downlights starts when homeowners and contractors fail to properly protect the casing of the light that is, quite inconveniently, out of sight and, most definitely, out of mind . The heat that emits into the ceiling space above downlights is something to be mindful of, and perhaps the main reason you would want to be aware ...
Can you cover downlights with insulation?
There are ways to safely cover downlights with insulation, but always check the manufacturer’s instructions to avoid a potential fire hazard. Industrial meets organic in this one of a kind kitchen covered floor to ceiling in natural wood elements with stainless steel accessories.
Does fiberglass insulation melt?
Be mindful of the insulation product you choose: Fiberglass insulation has a higher tendency to melt when in close proximity to heat , such as that emitted from a downlight. It fits loosely between joists, which permits air gaps to form around lighting, wires, pipes or other obstructions.
Do LED downlights heat up?
Aside from longevity and being eco-friendly, LED downlights won’t heat up nearly to the degree as their halogen counterparts. A cooler system immediately reduces the chances of fire, and makes them a safer product option if being surrounded by insulation.
What is an IC rated light?
An IC rated light can not only prevent a fire, but it can also save money in the long run as these lights can reduce the need for repairs. Plus, an insulated can light with an IC rating ensures that there is no energy loss occurring in your home. 2. Consider LED or CFL Can Lights.
What is can lights?
What to Know About Insulating Can Lights. “Can lights” add an elegant and contemporary feel to your home. Instead of handing from the ceiling, can lights or recessed lights are installed in such a way that their back is extended into the attic. So, all you can see is the front edge of the can-shaped fixture and the bulb.
How many watts does a can light need?
A can light that has an IC rating can be safely installed in a ceiling with insulation. Usually IC rated lights have a 75- 100 wattage capacity, meaning that as long these lights don’t consume more than 100 watts, IC rated lights will lessen the risk of overheating and a potential fire.
Do CFLS overheat?
CFLS also don’t overheat and can last up to 15 times longer than incandescent and use 75 % less energy. 3. Don’t Take the DIY Route. We understand that taking the Do-It-Yourself route is certainly cheaper and can even make you a more independent homeowner.
Can task lights be used for air leaks?
Homeowners are increasingly opting for these lights as they are incredibly versatile—they can provide spotlighting, task lighting and overall illumination. However, while these lights are great, they can allow for air leaks and heat exchange if they are not insulated properly.
Do LED lights overheat?
Standard incandescent bulbs can easily heat up quickly and even impact the temperature in the attic and the insulation in it. Consider using LED lights —they don’t overheat, and they last 25 times longer than incandescent bulbs and use up to 75 % less energy.
Question
The recessed lights in my house are accessible from the attic, but there’s no insulation around them because it says on the fixtures that they need to vent the heat generated by incandescent bulbs. If I replace those bulbs with LEDs, will that reduce the heat enough so I can insulate around the existing lighting cans? — T. J. Guinta, Patchogue, NY
Answer
While LEDs run much cooler than incandescents, their electronic components and external heat sinks do get quite hot; you would still need to keep the insulation away from your fixtures. And that leaves you with some serious problems.
Step 1
Inspect the fixture base where the foil backing is located and determine exactly where the foil needs to be cut. In the case of the foil interfering with the edge of the base, dry fit the base and determine how much of the foil backing you must remove to make it fit properly.
Step 2
Score the foil backing with a utility knife in the cut location. You may need to run the knife over the area a couple of times to cut through the foil. In the case of a screw hole, score a square section around the hole.
Step 3
Cut into the insulation below the foil with the knife. Cut as close to the base surface as you can.
Step 4
Pull out the cut area of foil and insulation with your hand. Pull the insulation straight off the base to avoid ripping off insulation from an area you do not intend to remove.
Step 5
Scrape the surface of the base with the edge of the utility knife blade to remove any residual insulation or adhesive.
