Insulating a house (remodeling project)
Some background information:
Zone – 5A – Shoreline Connecticut
Construction Year – 1958
House is framed with 2×4″ studs, sheathing is 3/4″ tongue-and-groove.
I’ve begun remodeling and I’m currently at the point where I’m ready to re-insulate my master bedroom. My plan is to attack one room at a time and the first is always the most difficult, so anything I do in this room I plan to transition into the other rooms (more-or-less).
My question is, what is the best approach to tackling this project?
I would like to air seal the best I can before I insulate, is canned spray foam an acceptable way to seal the top and bottom plates as well as where the studs meet the sheathing? Is there a better way?
As far as R value goes, I know fiberglass can only get me to R-13 in a 2×4″ cavity, is that enough along with air sealing? Can I do better without breaking the bank?
A lot of the information out there can get a bit confusing for me, I’m an avid DIYer but never knew the science behind insulating a home before.
If anyone can offer some advice or point me in the right direction I would appreciate it.
