SOLVED: Can You Insulate Over Recessed Lights?


Meeting the monthly bills can be a struggle for many people. Much of these outgoings are made up of energy bills, especially during the cold Winter months. Covering surfaces with insulating material, though, can be very effective at helping to keep your energy costs down.

This will usually help to pay for the investment many times over, while also helping to make your premises a more comfortable place. While insulating surfaces can be effective, however, it is important that the building is effectively sealed from heat loss.

But can you insulate over recessed lights and other similar features to obtain this fitted seal?

Just one small area that is not insulated will allow for heat to escape, decreasing the effectiveness of your installation considerably. Awkward fixtures and fittings, like recessed lights, are difficult to cover, and may cause issues with your efforts.

This leads to many people asking the question – can you insulate over recessed lights?

Avoid Overheating Lights

Recessed lights are generally found in ceilings, and the fittings are generally accessed from above through the floorboards or attic space.

Recessed lights are installed into holes that have been created in the ceiling and, without proper insulation, this provides an opportunity for a lot of heat to escape.

This is not normally a problem in itself, because heat loss can usually be prevented with an effective insulating material. The question of can you insulate over recessed lights, however, tends to be more centred around concerns over safety.

Light fittings emit heat. With standard lights, this is not a problem when insulation is concerned because the heat emitted will be retained within the room. At the most, it will help to make the room a little warmer, which is a good thing in the winter.

For recessed lights, however, much of the heat that is generated is radiated from the fittings above the ceiling.

It is often not a case of simply being able to cover these fittings with an insulating material, however. Because the fittings are emitting heat, they can soon overheat if the energy is not allowed to radiate. Not only could this affect the performance of the light, it can also present a potential fire-hazard.

Can You Insulate Over Recessed Lights Safely?

The potential fire hazard is something that should be avoided at all costs, not matter what. Still, though, leaving them uninsulated could lead to a great deal of heat loss and, in turn, expensive heating bills.

The good news is that it is possible to insulate directly over some of them. This depends on whether or not it is safe for the fittings to come directly into contact with the insulation material being used.

If your fittings have F Capped Approval, then it is safe for them to come into contact with insulation. This, in turn, means that it is safe for them to be covered with insulating material.

If you are unsure of whether or not your fittings do have F Capped Approval, you should contact the manufacturer to find out.

Another option is to use a loft cap. These caps go over the top of the light fittings, and help prevent the fittings from coming into contact with the insulation. You are then free to cover the loft caps with insulation in complete safety.

It is important to be sure that the caps themselves are not in contact with the light fittings; especially if they do not have F cap approval.

Fire Safety: Approved Document B

It’s also equally as important to choose an insulation material that is fire or flame resistant/proofFire Safety: Approve Document B covers all building regulation in England in relation to fire safety matters within and around dwellings. Your choice of insulation to adhere to these regulations and be fire safe!
