SPD does block 99.4% of IR as well as UV. In a test performed by Mercedes a few year ago in Mohave Desert the interior temp was 18 degrees cooler than the exterior temp w/o AC. It proved that a smaller AC unit could be installed in vehicles to decrease cost. Remember too that this tech is dimmable tint meaning it is not just "on or off." The tint levels can be controlled with a dimmer switch. Also, it is not legal to apply to windshields except on the top 4" or 6" which mitigates loss of power. It is dark blue in the default state and infinite variable tint all the way to clear w/o haze or "iris" effect. Smartglass.com for Research Frontier website.

Hi Kirk, Jan and I have been studying glass for our remodeling of the lower and lupper floors foors in Wisconsin. We'll be buying over $125,000 of doors and windows. All windows will be double paned and the area between the windows will have a inert gas inside the area. The outer windows frames and inner window have a thermal polymer that does not allow hot or cold temperature to radiate through it. The automotive applications have been around for a while. The Buick Road Master had nanoparticles that were oriented in the plastic middle sheet of the window that allowed light in that came in parallel to the road but reflected light that came in from over head in an effort to keep the cars cool and not degrade from UV. Not all people know that almost all front windshields are a sandwich of an inner glass and an outer glass, with a plastic liner in between the two panes of glass. In an accident the plastic liner keeps objects from breaking through the window (hopefully a back up system to the seatbelt). Thus its label of "Safety" glass. When talking to a very well informed home window salesman we discussed "High E" glass to keep UV out. We bought the upgrade for our southern exposed window on the upper floor. This window gets a lot of winter sun and summer sun. The Low EV window has a plastic liner in between the inner and outer panes of glass. It was described as a different hertz product than the glass and it simply bounces a lot of UV back and prevents it from entering the house. That's what I've learned about modern glass for home installations.. We chose to use "Marvin windows" as our entire river side of the home will be all glass. They have come a long way baby. I did similar windows when I remodeled my old school house. I keep the thermostat at 54 degrees during the winter. On a sunny day it hits 72 -74 degrees and the furnace never kicks in. My average heating bill is $18.00 a month for the year. It has southern exposure in the majority of the rooms. It also has two 150 year old Maple trees that absorb a lot of sunshine in the summer and lets the sun in during the winter after the leaves have all fallen. Bob
