1920 stone/stucco insulation? Closed cell spray foam in 2020?
1920 built home –
Currently ready for insulation after memorial of plaster and Lathe.
1st floor 4 foot stone walls exposed.
2nd/3rd floor – 1 inch solid 100 + year old wood planks covered by at least 6- 8 inches of stucco.
Roof – Planks covered by new plywood and new asphalt 30 year shingles.- triple thickness. Roof vent is placed on top. The third floor is living conditioned space,
What type of insulation should I use for the roofline. Closed cell spray foam or fiberglass? I would like to go green – however the insulation companies all recommend spray foam. I would rather under insulate in this 100 year old home (It has 8 inch beams) with extra space behind the knee walls, and under the peak.)
The 2nd/3rd floor stucco with wooden planks and framing.
1st floor solid stone wall with stone foundation – Wissahickon shist.
