Progress is being made on a little shop-improvement project. For many years now, I made do with a cloth curtain to "seal" the shop from the unconditioned upstairs storage area. That's changing as I'm finally closing in a proper insulated stairwell with an actual door at the top. This should make things a lot more pleasant during both the colder and hotter times of the year, especially given I plan on spending a lot more time in the shop going forward. I will mention that dealing with full sheets of OSB is not a fun thing for "one person's back", but it's a necessary evil. Fortunately, I can cut it upstairs with my track saw so there's no lugging it down and back up the stairs.
