Hi Jim,
I think Mylar would be pretty fragile at -40. They are for keeping heat out. I am not sure Mylar can be sewn.
The inside covers are going to be a sandwich that includes a layer of Mylar--but that would be unsuitable for outdoor use. Joanne's fabrics sells the material.
I put my existing vent and skylight "pillows" in large foil bags intended for bringing frozen goods home in hot weather. It made some difference on heat gain, and heat loss, so far as I can tell, over just the pillows.
I made "temporary" covers for the cab over windows, and sky lights from windshield cover material from the dollar store.
