VIDEO: Put insulation behind the radiator
In the past, radiators were often built in niches under the window because they were quite large and therefore less space was lost in the room. As a result, the wall is much thinner at this point than in the rest of the house, so a lot of heat is lost there.
Insulation with insulation boards or insulation wallpaper
- Insulation boards and insulation wallpaper for insulating a heating niche are basically the same thing. They are made of styrofoam and have an aluminum foil on the outside. The difference lies in the thickness of the insulation material. Insulating wallpapers are available on rolls, they are thin and can therefore be easily attached. Insulation boards are stiff and bulky and therefore more difficult to bring behind the radiator, but they also ensure better insulation.
- A styrofoam adhesive is required for both insulation materials, which you can buy in any hardware store, and you will also need one Spatula to apply the glue and a strip of wood or something similar that you use to press the insulation against the wall can.
- You can cut insulation wallpaper to the required size like normal wallpaper with scissors, insulation panels are best cut with a cutter or carpet knife.

Of course, if you have the opportunity to dismantle the radiator before insulating the niche, it will make the job extremely easier. Otherwise you have to cut the insulation boards so that you can slide them behind the radiator, so insulating wallpaper is more practical in very narrow niches.
