Operable exterior thermal shutters
We are building a duplex in Yellowknife, Canada – climate zone 8 (design temp minus 45 – same as Fairbanks).
Our winters are long and dark so some sort of (external) insulated window shutter is a huge energy saving opportunity. Our walls are going to R50, while triple pane windows get about R4.
I’m thinking of using 2-3 inches of Roxul board sandwiched between wood. That could give up to R12.
Problem is to be able to open & close the external shutters without opening the windows. Non-thermal shutters (or shutters with very low R-values) are common in Europe & I’ve found some manufacturers of handles that open the shutters from the inside:
1 – does anybody import or make anything like this in North America?
2 – I imagine the French example could be adapted to use standard window opening hardware like this: http://www.allaboutdoors.com/index.php?cPath=85_70 Anyone ever tried this?
