I think it's interesting, and I see no reason you shouldn't maintain it as part of your first aid page, or perhaps as an adjunct to that page. On the issue of the functional door shutters you describe above, I was wondering if they could be installed on the face of such a large glass expanse as I have, where the sliding glass doors must be about 7meters long and about 2 meters high. When I think of a wood shutter, it's something a bit more modest. But perhaps one of these motorized gadgets could be installed in a series, to cover the whole expanse. In my initial searches, the other green-building type sites didn't seem to do a good job in discussing window treatment type issues, so thanks for the help you've given. One interesting (too brief) discussion that I finally did find might interest you or others here: http://www.buildinggreen.com/elists/shades.cfm That discussion was interesting, but not too comprehensive, and pretty brief. I have to add something that has nothing to do with window treatments: http://www.nytimes.com/2004/01/20/science/space/20GEL.html?ex=1075179600&en=47b769c5dbc8bd9c&ei=5062&partner=GOOGLE This was sent to me by a friend the other day. At first glance it might not seem relevant to your project, but check this out: >In the 1980's, Dr. Tsou and others began to work with the material. "It has 14 >Guinness Book of World Records-type properties," Dr. Tsou said. "It's the >lowest density of any solid, and it has the highest thermoinsulation >properties.

But eventually the house would become too hot." Ok, so it doesn't meet your ready-for-use criteria, but it's pretty interesting, huh?
