Coavas One Way Window Privacy Film, Window Tint for Home, Daytime Reflective Mirror Glass Windows Coverings Heat UV Blocking See Out Not in, Black, 23.6 x 78.7 Inch

This film works very well for reducing solar heat transfer into your living space. I just installed 4 rolls in about 2 hours on 7 windows. The film is thin, but sturdy. In fact it will not tear so you must cut it carefully. I suggest using a sharp utility knife. The Included knife works but it’s flexible. I found a utility knife worked best with a fresh blade. You will notice that it appears dimmer looking outside through the film. the film is crystal clear and you can see very well. I recorded about a 20 degree difference on the floor between the filtered light from a window I had installed the film on and from one I had not yet installed. That alone is proof that this will help reduce cooling costs. You will notice the glass becomes hotter to the touch after installation as it’s absorbing some heat as it’s reflecting much of the solar radiation. Installation: use a lot of water with a little dish soap. Go slow and over size your cut. Once it’s on, squeegee it slightly to keep it in place. Carefully cut the film using a credit card to push the film tight to the window frame and glass as a guide. Once cut exactly to size slowly squeegee all bubbles out. Occasionally look at a steep angle to see bubbles. Slowly press them all out. Repeat. Slow is good and stress free!

It was is so simple to do it yourself

Instead of spending $3-4000 for some one to come and tint my doors, I decided to do it myself. I’ve never tinted windows or doors in the past so I was a bit nervous since I’ve read many negative reviews on how this film is flimsy and wrinkles easily to end up with a horrible result. Well, I read the instructions and I watched videos, I ended up installing 6 doors and all of them turned out OK. Installation is very technique sensitive and I can see why many had trouble. Once I got the first two done, the remaining 4 were straight forward. LOVE how the end result looked and this product did what it was supposed to do and I saved thousands!

Worked just like it should would buy again

4 stars as the use of this product tremendously reduced the heat coming in through my back door window which is in full sun each morning. Would have been 5 stars if the directions provided were more clear, the squeegee provided was larger/longer, and the film was easier to install! Great product to reduce the heat coming in through windows.
