I prefer the following products, in the 6' x 125' size, use the biggest piece of roll foil you can find, and give yourself at least a few inches of over lap:

For the thermal insulation, I prefer the following.

You combine the two products to create a isolate the type huge cage on the outside of the building.

You first lay down a thin skin of rigid insulation around the building, then close off gaps in the rigid insulation with tape and foam, then wrap the area in Tyvek, and then put the Astrofoil in top of the Tyvek. About every 48 inches screw a 1-1.5 inch wide copper sheet vertically, and then solider to a horizontal band  at the bottom of the foil, which you terminate in an earth ground. Then apply the outside all treatment, and complete the waterproof shell.

On the inside of the structure you fill the wall cavities with rigid panels, and lock it all together with aerosol foam to bind the thick panels to the structure. Then cover the inside with the Same Astrofoil that you used on the outside of the building, strap to the structure with vertical bands, and then solder the vertical bands to a horizontal bus that you secure to a master ground.

Then over this you secure two layers of sheet rock, lay up a ton of mud, sand it all down to a duct free state, then wet sand to make it all smoth as glass, then heat up the room, and lay up 6 to 8 coats of a premium titanium latex paint.
