External films, meanwhile, are – as their name suggests – meant to be installed on the exterior surface of a window. They sport the tough, exterior-grade construction that internal window films lack, which means they won't prematurely degrade in harsh weather conditions. They also use a strong waterproof adhesive.
The decision hinges on your specific goals. For heat reduction and glare control, exterior installation is often preferred. If longevity and cost matter more, interior installation is the way to go. Also, remember that there are specialised films designed for both interior and exterior installation.
While interior films offer ease of installation and enhanced aesthetics, exterior films provide superior solar heat rejection, UV protection, privacy, and glare reduction.
Typically, security window film is applied on the interior of the glass, but it can also be applied to the exterior. If you want added protection, you can install window security film on both the interior and exterior surfaces of your glass doors and windows.

Window film can be installed on the interior and exterior of windows. The application depends on the kind of window film and the application or what the window film will do. For instance, many window films (or window tints) used in residential homes are applied to the interior.
If it's brighter outside, then you will be able to see through the film from the inside out. If it's brighter inside (usually at night when lights are on in the home) then it will be possible to see through window film at night from the outside in.
Security Window Films
Non-metallized tinted security films last longer than metallized security films as metal tends to break down over time. However, it is not uncommon for a metallized interior-applied film to last 25 years or more. An exterior-applied clear security film has a life expectancy of up to eight years.
Typically, security film for windows ranging from 8 mil to 14 mil thickness is widely recommended for various security needs.
In conclusion, tinting your house windows can offer several benefits, including reduced heat, increased privacy, and protection from UV rays. However, there are also some drawbacks to consider, such as reduced visibility and the cost of the film.

Window film can stop unwanted air from coming through your window's glass. Window treatment specialists agree that window insulation film is effective. Window insulation film is incredibly easy to install as a DIY project.

Window tint is typically effective for about a decade, which is why we had to replace ours. Even though its UV-blocking benefits (window film can block up to 99.9 percent of UV radiation) were the main reason for installing it, I immediately noticed a few more perks once the film was fully installed in our office.
Can window film reduce heat loss out through my windows? Most of a building's heat can be lost through its glazing, increasing winter heating costs. Low-E insulation film applied to your existing windows will reflect radiated heat back into your room, increasing comfort and reducing fuel heating bills.
One way window privacy film is manufactured by sandwiching an ultra-thin layer of reflective metal between an adhesive bottom layer and a protective top layer. The one way mirror effect created by these types of privacy films occurs when sunlight reflects off of the windows they are applied to.
Clear Visibility at Night
One of the primary concerns people have when considering window tinting is whether it will affect their visibility while driving at night. Ceramic window film offers superior visibility and reduces sun glare, making nighttime driving safer and more comfortable.
Some types of window film are waterproof, particularly those films that are applied in damp and moisture-laden spaces such as bathrooms. Check with the manufacturer to find out if the window film is fully waterproof.
