I will be residing my house in the spring with vinyl.
The house is a 20-year-old gambrel, about 3,200 sq. ft., with 2×4 walls with fiberglass insulation.
I have already gone through the Efficiency Maine program, with air sealing and dense-packed cellulose in the attic. I did notice a big difference.
The house sits up on a ridge and gets a lot of wind.
Would it be worth the investment to inject foam into the walls from the outside? I currently heat with a wood boiler and baseboard heat and use about 5 cords of wood.
Thanks for your input or suggestions.
