I posted a question re: this but noone replied...I hope I can get some comments this time.

I have been seeing, on various websites, the emergence of variable tint windows. It is supposed to be the up and coming thing. The window can be switched from a dark to clear state and back with all the variable shades in between, blocking UV as well as infrared rays, eliminating need for window blinds and shades. Does anyone know of such a window and who makes them? Thanks in advance.

I think you're referring to those windows that are clear then when you hit a switch the substance between the panels gets excited and clouds or foggs the windows. These are highly expensive (like an lcd screen), require an electrical power source and are generally if at all, used in bathrooms. There not widely available, are usually custom jobs, and usually break the budget. issues regarding code and water/electric are often an issue as well as insulative qualities.

Thanks for the reply but I am not talking about the windows that you mentioned. Yes, you are right about it being expensive but I believe the technology that is in the lead is called SPD. It stands for suspended particle device. The windows that I am referring to do no 'fog up' the windows at all. They actually can gradually turn darker and lighter using a dimmer switch. Thanks for the reply.

I knew if they were adjustable they were electrified, tried to give him the right terms to search with, but he seemed to miss that they require electricity to work, and they are made by the same companies. I haven't heard of one that would do the job without electricity though!

In regards to the electricity needed, I did some research and found that current is minimal. Takes less than that of a doorbell. About 10 cents a day if you have it on continuously.

I do not think the suspended particle device windows are widely available at this time, but the companies which will make the film containing the suspended particles are currently ramping up to begin production.

This is the website of a company, SPD Technologies, Inc, which is licensed to sell the windows when they are availble. Maybe they can give you more information about the time to market and pricing.
