its been a while since i posted, finished the inside and got my co. Started my lean to to store some stuff outside. Ended up ordering 4' wide r25 for the ceiling. Its holding heat great. Also ran all my air lines in 1/2 inch black pipe.
i got it from lth steel structures. They sell all kinds of lengths and thicknesses. Up to 8' wide. I ordered and it was at my shop a week later. Definitely would suggest them if your looking for insulation.
Woodfor1, no kit i built it myself. Got a lot of supplies, poles, roofing from Ab martin in Lancaster. I drew plans myself and took me and my guys, after we were done with work, almost 1.5 years to build. Im north west nj. Blairstown
