Blackout Window Films, White Sides 100% Light Blocking Window Cover for Bedroom Nursery Day Sleeping, Opaque Static Cling Privacy Film, Non Adhesive Thermal Insulated Window Treatment, 78.7"x35.4"

I'm really happy with these. For larger windows it can become a bit patchy

I bought the white blackout supplied from uae and it turned out to be privacy rather than blackout.. it doesn’t give dark blackout coverage.

Not hard to install at all. Very dark as long as you don’t leave gaps around the edges. Most of the complaints about this product are installer errors. Clean the window very well and use lots of water when installing. This white ‘blackout’ film is perfectly fine.

Es muy complicado cortar justo a la medida de la ventana, por lo tanto no pude dosfrutar al 100% de los beneficios, pero en la parte que si cubre, bloquea la luz perfectamente, dentro parece que es de madrugada, además ayuda para que no entre el calor a la habitación.

I followed the instructions and used tips from other folks. 1) clean the window or glass you're about to put it on. 2) measure the window and have a bit of overlap 3) ensure you have a sharp box cutter or blade to cut the edges off 4) spray the entire window/glass with water before applying 5) ensure you take the backing off to apply the shiny side to the glass 6) wipe down the bubbles using a credit card. DONE!

I used this to cover a half moon window that's divided into 3. A very inexpensive alternative to an insert. A little tricky at first to get exact cuts. Measure bigger and cut down as you go. Definitely a 2 person job.

Easy to use. Blocks light. Enhances contrast.1. Measure, and cut an inch or two larger than you need2. Spray the glass and the film with a little water (a drop or two of soap shaken in the water will lower the surface tension of the water for fewer bubbles)3. Use a credit card, putty knife, or other thin, rigid tool to apply4. Take a bare razor blade across each side to trim excessI used this for a few aquariums. The black can work really well - I think it's great on the tank shown - but I'd going to redo another with a translucent blue because in some cases the black is too stark.The black can really make embers, rubys, and chilis stand out, but if you have otos, well, you might never see them again.
