Somewhere between visiting Burningman and moving to New Mexico I was exposed to double bubble reflectix. The stuff has become essential to life for us. We use it in our windows, curtains, cars, and now the guest room dome. We saved about 50% by purchasing it on ebay instead of locally. We simply tie it to our remesh and pour glass inbetween. This should give us a little bit of insulation around the glass so that we don't have a issue with the glass acting as a thermal mass.
