Many homeowners elect to have film installed on their low-e glass. Typically  their objective is to increase the heat rejection, introduce a fade protection or reduce glare.

A typical builder grade low-e window will provide for 20-25% heat rejection performance while most films will start at 50% heat rejection.

Additionally low-e windows do not provide UV ray protection which is 40% of the causes of fading.
