Cellulose insulation up against roof sheathing and in soffit in Mass.
Hello, I am a plain old homeowner with minimal building experience and not much money or time (5 kids) . I live in an old house (1890) and we pay a lot in energy bills and our hot air furnace is constantly running.
A contractor for the “state energy saver program” came out and began adding more insulation in the attic, the guy said he wanted to take down the styrofoam attic baffles that I had put up the night before, and dense pack the eaves with cellulose. I told him I don’t think that cellulose is supposed to up against the roof sheething like that or fill up the soffit. He got irritated at me not trusting his experience, then offered to loose pack it but it still seems like he’d just be filling up the soffits. I said I wanted to plug up toward the bottom of the eaves. He pointed out that the roof was not really vented in the soffits and had plenty of venting in the gables and towards the top of the attic (which is true). I had just read form articles on here that fiberglass and cellulose is not supposed to be in contact with roof sheething when possible. Then, tired to the back and forth he said fine we’ll cut it from the contract.
So now I have an attic floor that is very well insulated (but hard to navigate because of the 16″ cellulose and 1″ by 8″ underneath). But I have no insulation in the eaves which is roughly 1/2 of some of the 2nd floor walls. And no insulation in the vertical walls because they could not insulate because its an old house with double lathe walls and only a 2.5″ space in the walls (the house would not fit).
Was I right to ask him not to spray cellulose in the eaves if he wasn’t trying to keep it out of the soffit or use the baffles to keep it from the roof sheathing? I may have extended the life of the roof for 6 months but I’m afraid my energy bills will stay sky high. I had wanted to stuff a small piece of fiberglass batt down to block the cellulose from the soffit and have him spray on top of it but he was not interested in waiting.
What should be my next step for trying to insulate the eaves/bays? I was thinking about trying to stuff r13 mineral wool in each of the sloped bays because there is roughly 3.5″ of space under the attic baffles. It will be a nightmare getting to each one with the cellulose over the attic joists but I need to do something but want to make sure it’s the right thing.
Any advice is helpful. Attached is a quick diagram that I sketched but I got tired of the software. Thank you.
