It really doesn’t seem worth insulating my newly-airy bondtainer. Maybe not windows, either: bug screens with magnets (/on sliders, shower-curtain-style?) + barn doors for during storms/security made from the metal I’ve cut off?
This is the bounce after I jump up and down in one of the ends of the 40. Begrudgingly, I’ll add at least a stripper pole of reinforcement on at least one end. Spriral staircase to the top roof that doubles as a support on the other end?:)
