Measure the inside recess of your window frame and note width, height and the depth of the window ledge on the sill.
Thank you for such a wonderful product I would highly recommend these blinds to everyone. It’s simple to purchase and install Bedroom Blackout panels for any of your rooms. I am presently working a day shift at the moment but still use them all the time if I want to sleep in any mornings or to keep the heat down in the room on hot days while using the air conditioner. The windows that needed two sections I also find really good and useful as I can overlap the blinds and they just stay in place to vary the amount of light I want in the room. As soon as I got your blinds I found them wonderful as I could take them in and out of the windows after waking up letting in plenty of fresh air and light into bedroom and in particular on my days off. I had my windows originally covered in foil and the windows couldn’t be opened as the foil would be damaged and therefore was constantly in a dark room with no fresh air or no light and it was quite depressing after a while.
I just wanted to thank you for the Bedroom blackout blinds they are absolutely fabulous and I would highly recommend them to anyone doing shift work or just in general. If youre looking to add an elegant touch to your space, consider the Deconovo Thermal Insulated Blackout Curtains. I have been meaning on writing to thank you for the blinds we purchased in May 2013 and sorry for the late correspondence.
