Super insulation Technique Published on September 23, 2014 This is an update on the chicken coop made on September 23rd 2014. In this video I review the insulation of the roof and the beginning of installation of the purlins. This shows a superior way to insulate buildings. We use two layers of polyisocyanurate (aka, iso, polyiso) with overlapping seams. The critical installation technique is the insulation is applied over the framing of the building. Not between the studs. The studs have a very low R- value and heat escapes through every stud, top, and bottom plates. These insulation boards consist of a uniform closed-cell polyisocyanurate foam core bonded on each side by either a foil facer, paper or other material. Polyisocyanurate provides one of the highest R-values per inch of any rigid insulation (R-6.0 at 1 inch). Furthermore, when installed correctly the insulation sheathing creates a water-resistive, vapor and air barrier. Simply put, if the insulation isn’t continuous, then you lose environment control through thermal bridging. Typical construction techniques have exterior sheathing directly attached to the studs resulting in 1.5” of heat loss every 16” inches. And that’s not accounting for the top plate bottom plates, ceiling joists, or floor joists. Just search for “thermal bridging in studs in buildings” and select images and see what most structures are losing. The insulation needs to be continuous! No penetrations through the insulation. I also show how to construct a second structural layer in order to install the exterior sheathing, roof overhang and roofing. The inside of the coop has never come close to the freezing temperature despite the automatic chicken door being open even though the outside temperature has been as low as 23 degrees Fahrenheit below zero. I show how the wall insulation is continuous with the roof insulation. You can also see how the insulation is temporarily attaches with long aluminum screws and surface plates.

In this video, I show how I prepped the bed, planted Dutch Red Shallots, and used old moldy hay as a much to protect the shallots for the winter.
