This accessory for mobile air conditioning units has been specially developed for German tilt and turn windows (typical German windows). This solution saves energy so that it pays for itself within a very short time. A lower temperature is possible in the respective rooms in a shorter time. Among other things, it prevents heat from outside and the warm exhaust air generated by the air conditioning unit itself from flowing back into the room. As a side effect, it also keeps mosquitoes and other unwanted insects away.

It also seals the open window against moisture. Noise from outside is also dampened by the Hook and Loop Window Kit. This accessory can also be used for exhaust air dryers, both in the warm and cold seasons. The windows can be closed easily even when the accessory is fitted, first pull one corner inwards and then the other. They are fitted using self-adhesive Hook and Loop strips that are very easy to attach.

The problem: "Where to put the exhaust air hose?" is solved and nobody has to become a tinkerer or handyman. This accessory is suitable for all standard window sizes with a total circumference of no more than 400 cm. The applicable window size results, for example, from: 1x window height left + 1x window height right + 1x window width.
