Fall Colors
Finally the siding is complete, the roof and windows are complete. The rest of the work occurs inside, except for some yard work.

CAULKING
We went crazy with caulking. Before the insulation went in, we caulked all the cracks from the inside - framing around windows, horizontal cracks in exterior sheathing. We stoppered penetrations in the top plates for electrical wires with expanding foam. We caulked the exterior sheathing at all top and bottom plates. We shot insulation into crevices that the cellulose insulators would not be able to get to. Infiltration is one of the largest heat leaks in a house. With the Tyvek house wrap on the outside, the extra layer of foam, and the attention to detail on caulking and weatherstripping, this house should be as tight as a drum. Here is Qhyrrae, hitting a horizaontal joint on an exterior wall.

Insulation
Snow, anyone? We are insulating with blown cellulose, R21 in the walls, (plus exterior foam to reach R26) and R60 in the cielings. They blow it at the walls, with an adhesive and a slight amount of water. The insulation sticks to the walls, then they take a handheld machine powered by an electric drill and grind off the excess. They suck up all the waste off the floor, and blow it into another wall.
The ceilings are blown on top of a screen, which is then covered by sheetrock later.
