Air sealing old flooring
A portion of the first floor of our house has old pine flooring (no subfloor) with a lot of gaps and cracks that I suspect is a significant contributor to the draftiness of the house. Any recommendations on how to approach this? My thoughts were add 1/4” foam board inside each cavity.
This portion of the house is from 1890, has stone foundation and a drafty sill plate that I plan to insulate with spray foam next summer. The house was renovated in the 80s so has updated windows and fiberglass insulation in the walls but it is still a chilly house!
I appreciate any help or insight. Thanks.
