    Florida here. My AC only runs non-stop if all of this hits at once: I let it get hot inside, it’s 95F outside, and it’s late afternoon where I catch zero shade.

    The spray foam attic insulation under the roof is the bomb. If I had my druthers I’d force that in all new construction. Insane that we still use fiberglass and other crap.

        Haven’t heard that. I can say this, we have a Habitat for Humanity home and the insulation, structure, windows, etc. are well above code. They don’t play. The mission is to put people in homes they can afford, from the day you sign the mortgage, into the future.

        Yeah, the faucets, doorknobs, lighting, carpet, linoleum, all that is shit. But again, they don’t fuck around with structure (hurricane zone here) or insulation. Most energy efficient place I’ve ever lived.

        My understanding is that it’s not bad when done correctly, but if they screw up the install it can be a nightmare and a huge safety issue. They screw up the mixture and now you’ve got extremely hard to remove foam stuck to everything that’s going to off gas dangerous chemicals for 20 years. It can go bad enough to completely condemn the home.

          IIRC it can also cause the structure to rot if they get the vapor barrier details wrong.

            My understanding is that’s true of basically all insulation. Old structures were built with the assumption that they’d breath, and insulation wasn’t as important since they’d be heated by fireplace in the winter (either directly or using the fire to heat water for radiators) and air conditioning wasn’t a thing yet.
