Electrical and heating updates

I've been evaluating what needs to be done to the building so I can have my layout and it's not pretty.

First, the roof has no insulation, it is a metal roof after all. It does have a vapor barrier that has seen better times and needs reattachment in several places.

Second, no heat or air conditioning. Since we get down to the low teens in winter and the mid-90s in summer, this needs to be addressed.

I'm a little limited in what I can add to the subpanel (50AMP main breaker), given that I need 3 circuits for the layout area, so I have to shop with care.

I've decided to at least get an estimate for insulating the roof (about 1250 square feet slopes at a 3 in 12 pitch). I expect that to run 4 figures (ouch), but it would help not only the layout, but the rest of the building (used for a workshop and layout workbench).

I'm also going to install a forced-air heater mounted to one of the rafters, such that it will swivel to one side or the other depending on where I'm working the most. That may also necessitate a ceiing fan to help distribute the heat, but I'll wait on that until later. This is going to max out my circuit panel, so I may have to rewire some other circuits to avoid problems if I get too close to the max load.

The building has a loading dock to the side that I'm going to "partition" off by installing some vinyl strips like they do in some stores to control the airflow. That should keep heat where I want it, I hope.

This week I hope to install the old insulation I removed from the layout back wall upstairs to the west wall in the loft to at least help a little. I also want to mud and tape the layout area back wall.
