After putting one way film on the balcony glass, you can still see the interior at night, so what ca

At present, all the one-way fluoroscopic films on the market can not achieve the function of turning on the lights at night and not seeing the interior, but can only be achieved during the day, as long as the lights are turned on at night, they can see the indoors, and can only be replaced with two-way glass films or shielded with curtains.

Unidirectional glass film advantages:

UV Barrier: The long waves in UV light can penetrate glass and even 9 feet of water. The glass film can block more than 95% of ultraviolet rays.

Greatly reduce the fading of furniture caused by ultraviolet rays in the room, and prolong the service life of furniture, carpets, etc. Of course, it will also allow you to enjoy the natural sun bath without being harmed by ultraviolet rays.

Safety and explosion-proof: The strength of ordinary glass will be increased by more than 4 times after the film, which greatly enhances the impact resistance of the glass, even if it is broken by strong impacts such as earthquakes and typhoons, the knife-like fragments will not splash around. The glass fragments stick firmly to the membrane so that they do not cause injury to personnel.

When the transmission direction of the polarizing film is perpendicular, after the window is closed, no light can be seen from the outside. (Volatility of light).

Turn off the lights and close the curtains.
