Our Dark Exterior Reflective Film will allow 16% of light through.
It is designed to go on any flat glass surface and ideal where glass is not suited to internal film or when internal access is an issue. You can also use it on glass banisters.
As a rule, we recommend the darker films for south facing windows, where the sun is harsher. East facing windows will be exposed in the morning, when the sun is low, and west facing windows in the afternoon when the sun is high, but brighter.
The reflective quality of the film will also offer varying levels of privacy, when used on exterior facing windows. The darker the film, the more reflective it is, and the more privacy it will offer. The privacy effect will only work during day time hours.
For east and west facing, we recommend both the dark and the medium films, depending on how exposed your windows are to the sun.
North facing windows shouldn't be too affected by the sun.
