On a limited budget is it better to spend more money and time sealing the house or on more exterior foam
I have finally got quotes back for insulation lots of the sizes I’m after I can’t even get or prices went up a bit. So my question is I have to choose between 1” of halo foam which is vapor open and does breathe do to the way it’s made and also using a bunch of good tapes on plywood seams and windows a quality house wrap not tyvek or do I splurge and go beyond by budget for 2 1/2 foam which would then require a different approach with using smart vapor retarders inside the house and adds about 5000 plus time to the project all the way around.
essentially how much more savings is there from r5 to r10 is it worth the extra 5k or am I better off investing in better tapes amd sealing the house better and keeping the 1” foam and poly on the inside wall.
climate is zone 6 close to Chicago I would be above code and still vapor open to the outside with 1” foam using halo on the exterior so I don’t think I’d need to do the intello inside.
appreciate any thoughts this is my last hurdle on the house I just didn’t expect some of these prices
