Spray Foam Insulation. It’s so pretty. When it’s done. It’s not so bad to install either, most of the time is prep and cleanup, which still isn’t so bad (total project time ~ 3 hrs?, just one hour of actual spraying)

The goods we use are a two component system shipped in a box that leaves very little to chance… Open box, twist knobs, practice-spray to make sure yellow component + blue component = green spray!

The whole third floor and attic is spray-in recycled cellulose insulation. And the south elevation on the first two floors… Welllll it gets heated by the sun, right?
