Shop insulating advice

@GTXDAN and @Carnut68 sounds like a great idea on the door. It looks like Dan has a 2nd closing/locking mechanism on the sliding door, I only have 1 so I’ll add a second to help pull it tight on both sides.

My shop is already staying much more warm, but it struggles to go from 10 degrees to 50, but it’s no where near being done and airtight yet. It’s to cold for me to be working in it the past 2 weekends. Next weekend it is supposed to be in the Mid to high 40s and I’ll try to go out there then.

By my calculations I’ll need about 60 more foam boards to do the roof before covering it.
