I have a window I need to replace on a small wall on the north side of my h ouse. I got to thinking, I wonder if I could remove the siding on that one wall, replace the window, and add on top of the osn aome 1 inch insulating sheets to increase the r value of the walls. (I have batts in the 2x4 wall currently.)
I guess my question is, does this sound like a dumb idea and is it possible to take off vinyle siding and get it re installed looking right?
If this was doable I might as I have time add the insulating sheets to the entire house.
