Heat Control Window Film, Window Tint Sun Blocking Blackout and UV Protection, one-Way Privacy Mirror Reflective Film,Explosion-Proof Premium PET Material Cosmic Black, 17.5 Inch x 6.5 Feet

The window screen is fantastic once you get it installed. Excellent privacy and heat reduction.Installation is difficult. I did it by myself with a $5 squeegee and a $7 car tint kit that had a hard card and a utility knife. Installation would have been impossible without these tools.Highly recommend installing this with a second person, as the film is unwieldy. Highly recommend turning off all fans, as if any dust or dog hair catches onto the screen, you will not be able to get it off. Buy a little extra film, and practice on a small window or area before applying. Watch a few Youtube videos for pointers, and use excessive amounts of water.

The adhesion is quite sticky once the protective film is removed. The sticky side goes on the window; instructions don't say that. I recommend using copious amounts of soapy water for the application as well. Don't wipe immediately all the water as the instructions imply. Wait about five or six hours and then go back over the film and smooth things out; works better that way. I used this on the three windows that get the most heat of the day. I noticed that it wasn't as toasty in that area around 7pm. It doesn't reduce the amount of light, but does provide enough to keep curtains opens. You can see out but nosey neighbors can't see in. I have weird shaped windows; original windows from the 60s on my home, so fitting the film to the windows took some creative thought. There was an overlap of film, so I used a straight edged razor to cut things down to make the film fit. Looks good; can't even tell there is a film on the windows from the outside. This is pretty easy to use; take your time.

You can clearly see the side where I’ve put the reflective film and where I haven’t. It works great. Very easy application. You do need your own squeegee and water spray bottle so keep that in mind.

The glue is on the other side. The guide shows that it can be installed from inside the window but it only can be installed from outside. I took this to install it on my bedroom windows. But I can’t now unless I go 10 floors up from ground to stick it to my bedroom window from outside. Useless now!

this item is not really good, doesn't adhesion to the glass. Don't buy
