Almost all of a sudden triple glazed thermopanes are or should be gaining interest. Low E with argon as well in them. Basement wall insulation not optional here in Nova Scotia anymore. Code issue now. Inside and out.

Six inch outer walls a no no as well. Either 2x8 or 2x6 with 2 inch foam on the outside. These things have been in place for awhile now. Makes me look at windows a little more closely.

I tend to be fussy while building. Took the wife down after taking her out to dinner this evening to inspect one. I like her critique on things I do. I can count on her honest opinion.
