Does anyone know if there is any demonstration video to show me how to install the window seal? I have some challenges to install it.

For inward open window, you can refer to the installation video https://youtu.be/35aNfQWsjwg

how do i know if i need a 300cm or 400?

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.

Will it work with a skylight?

Hello, it is open from the top, then it can work, if it is center pivot window, it doesn't Thank you.

Will this work on my windows that open outward?

Yes, a window that opens outward is what I installed it on. Follow the directions very carefully, they are complicated, but they work.
