In short, yes, but there is no such window film that can completely block the view from the exterior during nighttime while allowing you to see through it from the interior at the same time. Privacy films can be considered many things, medium to very dark, reflective (two-way), frosted (allows light in) or 100% opaque blackout or whiteout films. The important thing to remember is as soon as you turn your interior lights on at nighttime, no matter how dark or reflective the solar film is, others can still see through it from the outside.
The only way to get complete nighttime privacy with a window film application is by choosing a frosted or opaque type of film which is part of our decorative window film line, these films will accomplish nighttime privacy but in most circumstances you will not see through the glass either direction day or night. Solar films are designed to see through, decorative films in most cases are not! You can slightly see through some ‘patterned’ decorative films. Window coverings are still the best option for nighttime privacy when you require transparency through glass.
