Here are some ideas on how to use window film for nighttime privacy
Window film gives nighttime privacy. Reflective or Dark Films can be your one of your best bets if used under the right conditions. The secret to getting these films to provide nighttime privacy is in being able to create an illusion or reflection. You essentially need to reproduce the daytime lighting conditions at night to create the reflective or dark privacy.
Remember those detective shows where a crime victim identifies a suspect from the other side of one-way window in a dark room? It’s the same principle.
To get the window film to look reflective from outside at night for nighttime privacy, you need to settle for less if any interior light while turning up the the brightness of outdoor lighting. Keep in mind that much of that bright light you’ll use outside will flow through to the interior as a soft low level light. You may also want to experiment using a dimmer on indoor lighting while someone observes the different levels of that light from outdoors at night.
Other factors that can add to the nighttime privacy factor is the darkness of the ceiling, walls, furnishings and even occupants clothing. Under optimum but maybe not practical conditions, you would want flat black ceiling, walls, furnishings and clothing with no interior lighting.
If someone from outside were to go up to the window to purposely look in, especially with a flashlight, they will see in. If someone just drove by from a distance, you would probably have complete privacy. It comes down to the level of privacy and peace of mind you’re seeking.
- You would not want computer or television screens visible from the windows as these are light sources that will compromise your nighttime privacy. Dim display screens when possible.
- Wall mirrors and opposing windows also provide light that could affect privacy.
