Without a smart window seal, you lose a lot of energy and warm air permanently flows back into the cooled room through the window, which is, of course, particularly inefficient.

The Windowseal puts an end to energy waste

The windowseal is more than just a window seal. This practical aid can be installed on any window in no time and prevents warm air from returning to the cooled room. Not only that, but the windowseal ensures that no insects can enter through the window and the window can simply be closed again when leaving the room, without removing the window seal.
