The tesa Moll rubber seals have helped to get the windows in our house poet. These are now 15 years of age and here and there it moved just a little - one has especially seen when candles were on the windowsill. Now with the seals, it has become much better and we can keep up with less heating turned up the temperature pleasant and comfortable. Because we have a system for controlled ventilation with heat exchanger in the house, I'm not worried about running out ventilation. That would be the only danger, because with the help of these seals the windows are just really tight. Even the Amazon price was unbeatable - in the construction market should be 1 role whopping 16 costs. So highly recommended.
