I have some windows I'd like to put smart film/tint over. Preferably I'd like a film that can be placed over existing glass. It would be opaque without voltage, and when electricity is applied it goes clear.
I'm having a heck of a time finding a retail store/website, where I can just click and buy, or even see their prices. I know it can be pretty expensive, but I want to know by how much. Seen many companies overseas, and no visible prices. Got one quote from a company of $150-$200 a sq. ft. But I think that was for the whole glass, and not just the film.
Anyone have experience with smart film? Know where to get it? An example of what I'm talking about is here. Looking for preferably USA distributors.
