Our high-quality window seal for portable air conditioners ensures an efficient and pleasant indoor climate during hot summer months. It is available in different lengths: 300 cm and 400 cm, allowing you to select the right size individually for your window, skylight, or balcony door.
Simply measure the three open sides of the window or, optionally, all four sides to ensure a complete seal.
Should your measurement be, for example, around 390 cm, we always recommend rounding up to the next available size and choosing the 400 cm seal in this case.

The seal is made of water-resistant, durable material (100% polyester) and protects your home not only from warm outside air but also from unwanted pests such as mosquitoes or flies.
With a width of 60 cm, it is particularly suitable for deep windows or older buildings, e.g., tilt windows or windows with side openings that swing inward or outward.
Important note: The seal is not suitable for sliding windows or center-pivot windows.

The window seal can be installed quickly and easily – without any drilling or additional tools.
It creates an airtight seal around the exhaust hose of your portable air conditioner, thereby preventing warm air from flowing back into the room.
This not only increases the efficiency of your air conditioner but also helps to save energy and keep the room temperature consistently comfortable.

Benefit from a simple solution to keep your home cool, comfortable, and insect-free.
With our window seal, you can enjoy the summer carefree – whether in the bedroom, living room, or office!
