Wall insulation choices on remodel
My name is Chris climate zone on margins of 5/6, doing an extensive remodel.
Thanks to those that helped with my attic insulation question.
Having that settled, we are moving on to the walls.
The walls are 2×6, osb, tar paper, air gap, then brick veneer
My contractor has offered me three choices
1) net and blow fiberglass
2) 2” closed cell then blow In fiberglass
3) fill entire cavity with open cell foam, although he was concerned about condensation issues with this one…by my understanding, I’m not sure that is a valid concern.
Which of these is the best option?, or is there a better alternative?
Just FYI, dense or damp pack cellulose or dense pack fiberglass are not things the building community around here are very familiar with, but if these are better options I could try and press someone to do it.
Thanks for any advice or opinions.
