HOOMEE Window Seal is also suitable for outward open casement windows. ALTERNATIVE WAY OF HOOK TAPE APPLICATION For certain window types and window corners can it be better to install the hook tape on the side of the window casement. This way the window can still be closed when the window seal is installed. IF YOUR WINDOW HAS A SPECIAL SHAPE AND THE WINDOW SHOULD NOT CLOSE EASILY WHEN THE WINDOW SEAL IS INSTALLED CAN YOU SIMPLY REMOVE THE WINDOW SEAL FROM THE HOOK TAPE OF THE WINDOW CASEMENT AND CLOSE THE WINDOW Another tip is to stick the hook tape on the outer edge of your window frame. This allows you to open and close your window effortlessly Review: Easy to install and remove when needed. - We got air conditioning unit last year but having the window open for the tube when it was 30+ degrees outside meant it still never really for cold enough. This easy to install seal makes a huge difference and I’m really impressed by it. The seal is simple to attach and just requires you to add the Velcro to the window frame and attach the seal. Once attached there’s four zips so you can have the pipe through one hole and still be able to open the other zips to get to the window handle when you need to. You can also cable tie the zips round the tube so it doesn’t come open. The seal doesn’t keep out 100% of the heat but it keeps out enough to make a difference. If you don’t want it attached during the winter months you can just pull the seal off and leave the Velcro up ready to use again next year. At £20.99 (it’s current price) I think this is well worth the money and I’d definitely recommend it. Review: Good product but a tight fit - Just bought a portable air con unit so needed one of these so I could vent the air hose out of the window but keep the room cool. My window's total exterior rim measurement came to 380 cm so I ordered the 400cm version. The item arrived same day, thanks to desertcart Prime. I found fitting relatively easy. The velcro tape has extremely strong adhesive - be careful not to stick it to your fingers. But because my window swings open from the bottom and has hinges on either side edges, rather than along the top, it has a large gap at the top when it is open. This means that the designed taper of the fabric strip only just overlaps at the top and there is limited spare material for making gussets at the window corners. I proably should have ordered the next size up. But it does seem to work well and the room cools down quickly. ## Features - NO MORE HOT AIR INCOMES HOOMEE window seal keeps the warm air coming from the hose of your portable air conditioner away by locking the hose between the window frame and the window itself. Our window seal leaves out unwanted guests, rain and crates a closed environment that keeps your room cool for longer. - EASY TO INSTALL NO NEED FOR DRILLING HOLES . You dont have to buy window kits, adapters for your hose or additional tools. All you need comes with your HOOMEE Window Seal! Simply apply the adhesive hook tape to the inside of your window frame and to the window itself. Attach the window seal to the hook tape. Then, open the zip on the window seal and place your air conditioner hose out of the window. At the end, close the zip tightly around the hose. Simple as it is. - UNIVERSAL - Suitable for all portable air conditioners and tumble dryersregardless of manufacturer. Whether for windows that open to the left or windows that open to the right, bottom hung windows or skylights, HOOMEE Window Seal will do the job.

I have some challenges to install it.** A: For inward open window, you can refer to the installation video https://youtu.be/35aNfQWsjwg **Q: how do i know if i need a 300cm or 400?** A: Hello, you can measure four open sides of the window and calculate the total length of them, if the total length is equal or less than 300cm, than you can select 300cm size, if equal or less than 400cm, than you can choose 400cm size. Important note, if you open the window, there is no gap where the window is attached to the frame, then you can just need to measure three open sides. Anything unclear please contact us via info@hoomee.com ,Thank you. **Q: Will it work with a skylight?** A: Hello, it is open from the top, then it can work, if it is center pivot window, it doesn't Thank you. **Q: Will this work on my windows that open outward?** A: Yes, a window that opens outward is what I installed it on. Follow the directions very carefully, they are complicated, but they work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install and remove when needed. *by H***S on 11 May 2021* We got air conditioning unit last year but having the window open for the tube when it was 30+ degrees outside meant it still never really for cold enough.
