Hardwood floor insulation advice
This past winter I bought an 1889 Greek revival in zone 5b (heavy winters). First time homeowner and I am in love with the house. These wide plank wood floors are possibly original and aside from a few splits are in good shape. But there is nothing underneath them. Literally can see the basement floor through a knothole. Since I moved during the winter I just closed this room for the season and focused on the rest of the house.
This summer I added the wood burning insert in the photo and plan to use the room this winter. But all the heat just disappears through the floors. Contractors and handy folk are hard to come by here and the good ones stay booked. It’s very very rural so there just aren’t that many people to begin with.
I could use some advice or suggestions on ways that I (with just basic skills/common sense) can add some insulation under these floors. Thanks in advance!
