## Description

desertcart.com: 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 : Home & Kitchen

Review: Provides privacy - This window film worked very well. It provided privacy while letting the outside light in. It was easy to apply and easy to remove.
Review: Worked just fine. - I bought this to obscure the windows in a storage space and it worked great and was easy to apply. I don't have any connection to the company but I'd like to address some of the complaints in the one star reviews because I look at bad reviews to make purchase decisions and some of the ones here are way off base. To the people who complained that the tools that were supposed to be included were missing... They were inside the cardboard tube the film was rolled around, one of you didn't even open the package before complaining about missing tools in a review. To the people who couldn't separate the backing sheet... If you apply a piece of tape to the backing sheet side at a corner it's fairly easy to remove – I did it and I have no fingernails to speak of. If that doesn't work apply tape to both sides and pull in opposite directions. To the people who complained that you could see through it... You both bought the "pure" color, you should have bought the "white." The description clearly says that the "pure" has "better light transmission" and the "white" has "better privacy." To the people who say it doesn't stick... Adding a few drops of dish washing soap (NOT dishwasher detergent) to the water in the spray bottle should solve your problem.

## Features

- 【UV Protection】Continuous exposure to the sun will cause high room temperature, aging furniture, and sunburn on the skin. Heat insulation film that can block 90% of UV and 50% of heat.It can perfectly solve this problem, and you will have a feeling of visibly cooler after use. It can also save your air-conditioning electricity bill.
- 【Privacy Protection】After sticking the window film, the outside looks like a mirror during the day, and I promise you can’t see inside even if you use a telescope. But the inside can still clearly see the outside.It also makes the house more beautiful.
- 【Safety Protection】When the window glass is hit by objects entrapped by a ball or typhoon, the splash of glass slag can cause serious injury to people. Only PET window film with glue can be explosion-proof. Only our videos dare to do real tests.
- 【High Quality】What an embarrassing thing if the window film blisters and fades after exposure to the sun. In summer, the glass temperature can reach 60℃, ordinary window film will definitely foam, but the window film with glue PET material will not. avoid frequent replacement, waste your time and money.
- Referring to the video will be very helpful for you to paste the film! I am more than happy to answer any questions you have. We cherish every opportunity for service, if there is any dissatisfaction, I will definitely solve it for you, as long as you contact me.

### ⭐⭐⭐⭐ Affordable blackout alternative
*by M***R on August 20, 2025*

I ordered the 31.5-inch size after measuring my windows but still ended up cutting it down on the sides. Thankfully, trimming it was simple (I used a Xacto knife) and didn’t affect the look at all. Installation was pretty straightforward and much easier than I expected. Once up, it made a huge difference in my daughter’s room, it darkened the space so she no longer wakes up at the crack of dawn with the sun! I didn’t exactly try my hardest to push all the bubbles out but I did use a squeegee to help push the biggest ones out.
