Spray Foam Went Well
I just wanted to thank all the authors and community members here. I’ve written here often, even had my house featured in an article:
The issue in this article — was successfully addressed. We installed R-49 closed cell HFO foam under the roof sheathing, after checking it was dry.
The same contractor also installed above code quantities of HFO foam on our Rim Joists yesterday.
We are now going through a regime of aggressive air sealing and insulating!
The hope is to get to the point of net zero.. where our soon to be installed air to water heat pump will produce heat + ac + dhw, and reduce our load so much that our usage will be covered by our solar panels (maybe we will need to buy another small array).
