Near zero temperatures, and 2 or 3 pretty incredible snow storms. Contractors miss 2 days but it's not a complete loss; the pond skating is fantastic as long as you dig out a spot.
The sun room wall is fully insulated and actually quite cozy, and the new tiny windows are slick.
The team starts on the front of the house zipping towards completion of insulation. The boiler is spending long periods off.....even when outside temperatures are frosty. We're using less oil, but some post-project number crunching is required to know exactly how much less.
I have a new hobby. I'm driving down the street looking at the contours of other people's roof snow. You can figure out alot about a house's attic layout and rafter insulation just by looking at snow. We'll get some pictures up here soon.
