Insulation in 1926 house
I am flipping an adorable 1926 Cottage. There was no AC system so I installed one. I had to get creative as to installing the ducts. But it’s still HOT upstairs. I live in Central Texas. There is no attic space. The upstairs looks like an attic conversion, but it was built this way. The walls are stucco or plaster. It’s like cement on metal mesh. Then there’s about 8″ of airspace and then wood with the shingles on top. I did put two AC vents up there, but it’s still hot. Can I put spray foam insulation in the space between the roof and ceiling. I would have to drill holes in the stucco. I’m reading that’s it’s not a good idea, but all of those people are in Canada where it’s cold. I’m in Texas where it’s HOT!! Thanks so much for your help.
