Due to the increased heating costs, many consumers want to save energy.
You often hear that curtains help, but how big is the difference really?
Kassel – The energy crisis is causing rising heating costs.
Many citizens therefore fear a high bill at the end of winter.
For this reason, some consumers do not want to turn the heating up to the max.
But there is also often talk of being able to save electricity and heating costs without making major cutbacks.
Instead, you should save energy with a few little tricks.
One of those pieces of advice that you've probably heard by now is that curtains help because they help keep heat in the home.
But does it really affect the heating bill if curtains are attached to the windows?
Can curtains really save energy?
In fact, curtains save energy, so the advice is right.
"You may not believe it, but even a thin and light-transparent curtain can improve the energy efficiency of an older window that was installed in the early 90s or earlier by up to 30 percent," Christian Handwerk told the
editorial network Germany
He is a consultant for energy-efficient construction and building physics at the NRW Consumer Advice Centre.
He goes on to say that curtains are often underestimated as a way of saving energy.

However, it is important that the curtain is attached correctly.
To do this, he would have to completely cover the window.
If this is the case, a small air space forms between the room and the window, which also insulates.
It should also be ensured that the curtain only hangs in front of one window.
If it is in front of the heater, for example, it also shields the heat from the heater from the apartment.
"Of course it has to be the other way around.
It must be made difficult for the heating air to flow to the cold glass pane.
It should flow past the curtain on the inside and then into the room," said Handwerk.
The information website pro-energiesparen.de writes that the heat can be kept in the apartment particularly well with special curtains, for example made of natural felt.

Even with thin curtains up to 30 percent
Saving energy with curtains: What else can you pay attention to?
There are numerous energy guzzlers in the household, the windows are just one of them.
Even small appliances like the kettle can save energy.
In order to reduce heating costs in the apartment, you can also reduce the room temperature a little.
With just one degree less, costs can already be reduced by up to six percent.
