Deep window wells
I am looking at having new windows installed as mine are completely shot. My house is a 1930s build date. There is no insulation outside of asbestos cement siding. I know I would eventually like to reside the home in a modern material with 4 inch foam insulation under. My question is, what is the best way to go about this. Install the new windows and just do jamb extensions when I do the foam? Install extra deep wood jambs before new windows?
