Here's an early morning shot of the new insulated roll shutters which A&A Awnings just installed. The slats are about 1/2" thick, foam filled, powder coated aluminum. It's motorized and the control is wireless so it can operate it from anywhere within about 200 ft. Individual shutters can be up, down, or anywhere in between for shade control. In this installation, there are 8 separate units which can be controlled independently, though a unit could have been designed to cover any number of windows since the system is custom designed and built.
When down, they seal tightly and have allowed the internal heater usage at night to be cut by 1/3. It's like something out of Star-Trek when they all go up or down at the same time.
Serendipitously, they fit right into the passive solar house as if it were designed with them in mind, which, of course, it wasn't since the house was built in 1980.
Because they're foam filled, they're not as structurally strong as hurricane shutters, but will give some protection up to category 1 storms, though that's not their primary function.
Although expensive (the whole system was about $12,000 installed), Jim & Genny Jacobs can highly recommend them should someone want rolling, insulated shutters like these. Warranty is 5 years on parts, 1 year on labor.
