The bedroom is often a refuge where one must feel protected from external aggressions such as noise, humidity, cold or heat.
Although it needs less heating than other living rooms in the house, good insulation is essential to make it as comfortable as possible and ensure a good sleep, while reducing energy bills.
Insulate its walls well
After the roof, the walls are a great source of heat loss.
The internal thermal insulation must be done in priority on the cold walls, that is to say those giving on the outside of the house, in order to control the passage of air.
Unlike so-called exterior insulation, this method makes it possible not to embark on major facade work.
You can go it alone if you feel up to it, or call in a professional who will guide you on the different methods (with panels or in bulk) and possible insulation, from glass wool to rock wool, from linen, wood or hemp, passing through polyurethane or cellulose wadding.
This kind of work is rather done during the hot season.
Insulating paint at a lower cost
If you don't want to break everything and act quickly, you can opt for solutions that are certainly less effective but easy to implement, such as insulating paint.
It is composed of special resins reflecting infrared and acting as an anti-cold barrier.
It arises like a classic painting and comes in a wide range of colors.
Another option: cork panels, which can be found in rolls and which are easily glued to the wall.
Floor insulation
If your bedroom is on the ground floor, its floor may be directly placed on the concrete slab, which can generate large energy losses.
The simplest technique consists of insulation from the bottom: an insulation is attached to the interior face of the floor, using several possible materials (expanded polystyrene sheets, polyurethane foam, glass wool, cork, etc.).
In addition, it is important to choose your floor covering: the tiling will be "colder" than a wooden or vinyl floor, for example.
Long unloved, carpet is also making a comeback in interior design.
Available in several shades, it has the advantage of being able to be installed easily, without major work, and of giving the room comfort while retaining the ambient heat.
The importance of a good window
When poorly insulated, windows create significant drafts.
If they are too old and let the cold pass, it may be time to change them.
Manufacturers offer a multitude of models designed in high-performance materials such as PVC, which has a very good quality / price ratio, wood, both warm and resistant but requiring more regular maintenance, or aluminum, very aesthetic. .
In all cases, they must meet the criteria imposed by the thermal regulations in force.
Finally, for optimal insulation, be sure to choose a good double or triple glazing, which is very effective.

Some economic tips
If you can't afford to change your windows, cheaper alternatives can help you out.
First of all make sure that they are well caulked, by remaking the joints regularly (the material costs a few euros in DIY stores).
Also install thick or thermal curtains (made of an insulating material), which limit temperature variations and keep you warm.
You can also opt for an insulating film, which adds an anti-cold layer to the existing glass.
Likewise, if you have shutters, remember to close them during the night: it costs nothing and it saves a few degrees.
Finally, think of the classic but effective rollers and other door sills, of the thick carpets on the floor (which warm cool surfaces such as tiling), of the heat-reflecting panels to be placed behind the radiators or of the waterproof recessing boxes, to install on electrical outlets to fight against air infiltration.
