Loft insulation helps to slow down the transfer of heat between your home and the outside environment.
It is mainly installed on the roof or floor to prevent heat transfer and make your home warmer in winter and cooler in the summer.
But, can you use loft insulation under kitchen cabinets?
Yes, you can use loft insulation under kitchen cabinets, but keep some small vents available for the appliances attached to the cabinets. In this way, your kitchen’s temperature will not fluctuate and will maintain an adequate temperature, and also, the large appliances will not get hot due to the vents.
Before installing the insulation, do check out these conditions.

Where Are Your Kitchen Cabinets Installed?
The position of the cabinets plays an essential role in maintaining the temperature inside the cabinets.
If your cabinets are installed on the interior walls, then insulating them will be fine, and you can control the temperature to some extent.
But if installed on the exterior walls, then only insulating the cabinets will not work because the heat can quickly transfer through the walls to the cabinets, and your insulation will be wasted.
So, first, check out the position of your cabinets, and depending on that, you have to take the decision.
What To Do If My Cabinets Are Installed On The Exterior Walls?
If your cabinets are installed on the exterior walls where most people have them, you must insulate your walls first.
Insulating the walls will slow down the transfer of heat, and your kitchen will be much warmer than before.
But if you want to insulate your walls, there are better options available than loft insulation. The best option is to inject foam into the walls, which will completely fill the cavities like the cracks and the gaps, and your kitchen will be much warmer.
Foam injection doesn’t sag, settle or compress over time and it will maintain an adequate temperature by keeping your energy bills down. It is far better than regular fiberglass and cellulose insulation.
You can also try spray foam insulation instead of foam injection, which also works more efficiently than fiberglass and cellulose insulation.
So, the main objective is to keep your kitchen warm to prevent your food from getting cool quickly.
How To Install Loft Insulation Under The Cabinets?
Installing the loft insulation is not tough to work with, but you can hire someone to do it if you are not confident.
The primary step is to fill all the gaps you think the cold air is coming from. So, take a roll of loft insulation and cut it, and top up all the gaps.
If you have a few inches gap underneath your cabinets, then you can easily fill the gaps. But if the gaps are negligible, then it will be difficult to insulate with loft insulation.
In this situation, when the gaps are very tiny, you have to use spray foam. It will fill all the small gaps to some extent, and your cabinets will be insulated. If you have some gaps behind the kitchen cabinets, then insulate them too.
Insulating the kitchen cabinets will stop the heat transfer to some extent, but it will not prevent it entirely.
To get proper insulation, you have to insulate the entire kitchen so that there are no gaps left in any part of your kitchen, and your kitchen will be much warmer.
