Neat and saves on heating costs.

In the stairwell far drafty and chilly. A simple shower curtain rod between the walls stretch I have two curtains with eyelets buy, so you can * easily * overlap in the middle. The folds help dams. The difference when you go through is clearly and automatically think to pull to the curtains again. The cold out. You can now even venture so that the stairwell to heat something that would previously have been a waste of money. In summer the sun beats down before the door, then to be seen what the curtains still can. I am satisfied with the processing.

Now I can say in addition that in these extremely hot days the curtains also block heat. The chimney effect that heated air can penetrate unabated into the house and up in all the rooms through the glass door is broken. Money well spent and they can also be washed. So I wait, but until the heat wave subsided. :)
