So today we began installing a foil backed glorified bubble wrap under the membrane. The one we wound up using was Ecofoil, though there are a number of similar products on the market, including Reflectix and a few others. This is basically two layers of small bubbles clad both sides in aluminized mylar reflective material. The resultant fabric is VERY tough, and with an air gap, you can get about R 7 out of the installation.
We're lining the interior between the rafters with a selection of cool old tablecloths we've been collecting over the years, which will not only give us something to look at and make the bedroom look a bit less like the interior of a beer can, it will give us another 3" or so of air gap as insulation.
It's time. The trees are turning in a rather spectacular show of color along the river, and tonight will dip into the 30's for the first time this fall.
