About this item:
  • KESPEN sun blocking window film can effectively block 82% of infrared rays and 90% of UV rays which may hurt your skin, prevent your precious furniture and interior decorations from fading.
  • The window tinting film for home reflects some of the heat back outside, thus reducing the amount of heat transmitted through window glass, which can keep cool in summer and retain heat in winter, helping you save money by cutting the high energy bills.
  • This one way window film provides superb privacy during daytime, the mirror reflection of privacy control window film allows others to not see any interiors from the outside, effectively protecting your private space. But when inside light is stronger than outside, loss of light difference, such as the lights turning on, the mirror effect will disappear and will be seen from the outside. So at night with this mirror tint, it is necessary to draw the curtains.

Since I did not know this note this is only for single pain windows as if you put it on the inside of a double pane it will cause the gas Gap to overheat and fail, if you're double paying Windows no longer have the gas Gap safe to use on the inside otherwise put this on the outside of your windows perhaps with a screen in front of it to make sure it doesn't fall off in the middle of summer that way you won't lose any insulation.

It does in the daytime, doesn't at night. This is typically how window tint works.

If you want privacy at night, use curtains or blinds. It's not that difficult. This film allows you to leave the blinds/curtains open during the daytime while providing privacy when it's light out.

Community Reviews

This static cling window film is mainly useful for daytime privacy, giving a mirrored look that lets you keep blinds or curtains open while still blocking views in. The effect depends on lighting, and it can work especially well with an outdoor light reflecting off the glass. At night, the privacy drops off sharply and inside lights can make the room visible, so curtains or blinds are still needed. It is also flagged as a poor choice for inside application on double pane windows, where heat buildup could damage the seal.

Common Questions (3)

  • It works as daytime mirror privacy, but at night it does not block visibility the same way. If lights are on inside and no outside light is reflecting, people can see in clearly; curtains or blinds are needed for real nighttime privacy.

    Thomas911FALDameTimevelocirapt0r

  • Yes, it can work on car windows and is described as sticky enough to stay on. The practical expectation is that it should be easy to apply and removable, though the comments do not confirm long-term bubble-free durability.

    dxxviFAL

  • It is safest on single-pane windows. Applying it to the inside of a double-pane window can overheat the gas gap and damage the seal, so outside application is suggested if you want to avoid that risk.

Is it easy to put on a car window? I don't need it to be perfect as long as it lasts for more than a year, has no bubbles and can be taken off easily.

Are you more of a foil person for privacy? I've heard it can be used for windows and hats!

Most people want more privacy at night when this doesn't work.

If you care more about your privacy than looking out your window, frosted glass privacy films are much better. Examples:

You won't get privacy at night UNLESS you have a light on outside. The light will reflect off the windows where it will be very difficult for anyone to see inside but you must have a light on. If your outside light is off and you have lights on inside your home, you can clearly see inside the home. Remember window tints like this reflect light.

I think these can break the window if a hot sun reflects on them too long.
