We are purchasing a home built in the mid-1980's. Current attic insulation is inadequate for Virginia climate (roughly 7" loose fiberglass, unevenly distributed). The home also has an attached large modular sun room that was built onto the deck--we are curious to see if the floor of that space is insulated at all and are considering our options if it isn't.
