Air sealing and insulation upgrades before major renovation?
We are in early stages of planning a significant renovation (including potential small addition), which is realistically 2+ years away. Is there any reason to not do air sealing and insulation retrofits on our circa 1900 home now?
Some conditions to consider:
– Rim joist is uninsulated
– Little wall insulation
– Attic floor and basement ceiling insulation is degraded and thin
– Exterior board sheathing has no wrap (beyond that is degraded wood shingles, 1/2 inch board, and vinyl exterior)
My concern is whether any upgrades will significantly hinder/impact/add to cost of the future renovation.
