  • I am not a construction expert, so check your sources on this.

    My understanding is that, for new construction, spray foam is most often used in areas that aren’t likely going to be damaged by condensation, such as against concrete, or metal. I had looked into spray foam for my home, because my home was built in the early 80s–before building codes existed in my area–and there’s no cladding on the house and just fiberglass bats between the studs. Because there’s no cladding, there’s much more air incursion through the bats, esp. since the interior walls are lapped wood paneling rather than wall board. Spray foam would have been a total air barrier, but it would end up being applied directly to the inside of the exterior siding, which would be a nightmare when siding needs to be replaced, and would probably cause moisture issues.

    The best solution appears to be to use 3" EPS foam cut to fit between the studs, and then use spray foam to fill any gap between the studs and the EPS. That still allows an air gap between the foam and the exterior siding so that moisture can evaporate.

    In the case that’s being cited here, I’m not sure why they opted for spray foam over EPS or fiberglass bats. If their home is well sealed, then bats should have been perfectly sufficient, although they have a lower R-value per inch than EPS. Oh, and the difference between polyisocyanurate and EPS/XPS is about R1.5/inch, but that difference drops to about R.25/inch after a decade. That meanst that you don’t gain much in the long term when you use faced polyisocyanurate board. I’m not sure what blowing agents are used for polyiso; it might be more environmentally friendly to manufacture.



  • I’m a reliable voter. I vote in ever state and national election (but not local ones, because my residence is weird; my address is technically in one county, but the town my address is in is in a different county, so I wouldn’t have any political connection with the local races that I can vote in).

    It would take a very unique ® for me to vote ®. Given their traditional policy positions that are pro-business, anti-choice, etc., I’m not sure who could even go that way. I suppose I could be convinced to vote for a libertarian running as an ® if they were able to make a case that they stood for strong individual liberty protections while also supporting strong regulations on businesses.

    On the other hand, there are definitely (D) candidates that I would simply not vote for at all, like any (D) that was anti-choice.

    Prior to 2016, my parents were 100% ®; they’ve switched almost entirely to (D) after seeing how radically the party shifted.
