It is through windows and doors that most heat escapes, 35-45%. Therefore, even a well-insulated house may lose energy faster than we think. If you want real savings, it is worth doing one simple trick with window coverings.
First of all, it is worth considering why does heat escape from the apartment? Well, the temperature difference between the inside and the outside is to blame. Therefore, it is worth creating an additional layer of air that will reduce the transmission of energy to the outside. We can do this using window coverings.
Well-fitting window blinds can reduce heat loss by up to 7%. This number may increase to 10-12% if we choose special cellular (pleated) blinds. They create the best insulating layer.
To save on heating, just do one trick with window blinds. For the evening, we only need to close both the external and internal blinds. Why will this work?
An additional layer of air will be created between the external roller shutters and the glass, which will act as a natural insulation slowing down the escape of heat. In turn, internal blinds, especially the mentioned cellular ones, will retain air, making it easier to maintain the desired temperature in a given room.
Interestingly, dense curtains can also create an insulating layerbut less effective than window coverings. Moreover, we cannot cover the radiators with them, because then we will block their operation and the heating costs will be reduced.

As mentioned, to save on heating, it is best to close the blinds at night during the day, we recommend using solar energy. This way we will gain natural heating.
You also need to take care of proper ventilation of the room, to prevent moisture accumulation. Finally, it may also have a negative impact on the durability of internal blinds.
Let’s also remember about regular . Thanks to this, we will maintain their full functionality and prevent the accumulation of dust that limits their effectiveness.
Let’s check the condition of the window covering mechanism on a regular basis. They must raise and lower smoothly, without resistance.
