Alternative for the less handymen
If do-it-yourself isn’t your strong, don’t panic. Do-it-yourself stores offer thermal insulating films made of aluminum, often sold in rolls. Although more expensive (around 20 to 50 euros for 15 metres), this option is ideal for covering several radiators or for those who want a ready-to-use solution.
The concrete benefits of this tip

By reflecting the heat towards the inside of the room, this method makes it possible not only to enjoy increased comfort, but also to:
Reduce your electricity bills by optimising the consumption of your radiators.
Extend the life of your heater, as your appliances work less intensely.
Moreover, this tip is particularly effective in old, often less well-insulated, where each degree gained counts.
