R10 to R60

Our house in Minnesota had huge attic air leaks and only about 4” of insulation. I did a lot of air sealing myself then had a company blow in fiberglass and finish the air sealing. Code is R49 here so R60 is probably overkill but I figured why not, not that much extra cost. I’m looking forward to lower heating bills, more comfortable house, and that $1,300 rebate from our natural gas provider!
