Any good film will give you UV protection.. I believe it was 99%. The metalized film will give you a little better heat rejection, and yes, the silver tint will give you the best, its just not legal in most states. When tinting double pane house/commercial glass, you have to use reflective tint exclusively, because the black tint absorbs the heat and will cause the window to expand and eventually crack, thats why you see buildings with reflective tint instead of the black/bronze tine you usually see on cars.
