Hello to all. I'm new here and would love some feedback. I'm re-siding our house. I'll will be stripping all to bare wood. I just installed new Andersen 400 series "new-construction" windows. My dilemma is whether or not to install "green-board" for insulation purpose. Whether I do or don't, I will be wrapping the house with Tyvak. Is it worth it? Do you gain enough "R" value to out-wiegh the costs and extra work? And if so, do you Tyvak to house then green-board or green-board first then Tyvak? The siding that my wife is in love with is Cedar Impressions either Mastic or Certainteed. Being it's a thicker siding how do you compensate around windows and doors etc if green board is used. Thanks to all and all feedback is welcomed.
