  • I have done the rim joists in my basement using a similar spray foam product. The biggest recommendations I have are:

    1. Use the kind of gun pictured and not the cans that come with a straw. It is much easier to apply consistently and you can actually stop work and start again the next day using the same can. The straws work OK but they always get clogged when you stop for a bit so only use them if you are working on a small area and plan on using the whole can in one go.

    2. Look into the difference between closed cell and open cell foam. I’ve never seen closed cell come in a can like that so I’d bet money that is open cell foam. It works great for air sealing but you need to apply a ton of it to get an appreciable R-value. Closed cell foam is a lot more expensive in the spray form and is a 2 part mixture that is more complicated to work with.

    What I ended up doing was buying some 2" closed cell foam board at the local hardware store. It’s relatively cheap in board form and is easy to cut. I cut a piece of the foam board to fit inside the rim joist space and then used the spray foam to air seal both the rim joists themselves and the small gap around the foam board. I think this is the most effective way to do it unless you go for the 2 part closed cell spray foam but that was more than triple the cost of the foam board + open cell spray foam.

    For comparison, the 2" foam board has an R-value around 8 and, if memory serves, you would need something like 8" of open cell foam to provide that same level of insulation. You can get an equivalent R-value with 2" of the closed cell spray foam but last I checked the spray stuff was about $800 and an 8’x4’ sheet of 2" foam board is around $60.



  • I don’t think you’ll know for sure unless you ask, and even then there’s no guarantee you’ll get a real answer.

    People are all unique. Just read these responses here. There are people making contradictory claims because each one is focusing on different parts of the story from different perspectives. That’s not an indictment on their judgement it’s an illustration of the reality you’re facing.

    The truth is none of us know what you did or didn’t do wrong, or if there even was such a thing. We don’t have enough information and I don’t think you could provide all the necessary information even if you wanted to. Social interactions are just too complex to be accurately deconstructed in a few paragraphs.

    In the end, just think about what you want and take a step in that direction. If you want to see this guy again, say that to him. It doesn’t have to be more complicated than that as long as you’re willing to accept that it might not turn out the way you want.







  • I do think the fediverse is better than the corporate built alternatives but the more time I’ve spent here the less I believe that it is a great solution. People are the fundamental problem and people control every instance, moderate every community, and post every comment (excluding bots which are their own problem). The amount of infighting I’ve witnessed here over trivial bullshit is astounding. People are constantly calling for defederation over one offense or another. Much of it rivals Reddit in it’s pettiness.

    It’s true that no single entity controls it all, and that is an improvement, but everything still gets fragmented so much that I don’t think I believe it can reasonably grow beyond what it is now. Not without running into variations of the same problems as the others at least.

    I think the simple truth of the matter is that humans can’t help this kind of tribal behavior. We group ourselves together using all kinds of labels, some broad and some incredibly specific, but the end result is always the same. Those with the labels I gave myself which are most important to me are my friends and those without them are my enemy. Until that primal need to exclude others is gone, any communal space we create will devolve to the point that there are effectively multiple siloed echo chambers that rarely overlap.

    That was more of a rant than I initially intended, but the point is that I don’t think the fediverse would have solved this problem. If a federated version of Instagram was the dominant service for that kind of activity then the No Kings account there would have been censored by many groups for many reasons. Enough so that I don’t know that the impact would be any different.
