I use these curtains in the conservatory. Since my thermal curtains are expensive initially, I would need for the conservatory more of them, I manage myself so: let the normal curtain on the high wheels. Towards the interior ancient warmer Sheets install and then after that I called with clips. Donau brackets these curtains. So everything looks good and the winter cold out. Have very good experience with this type of window Kältschutz.
