Now I am encouraged to do exactly that.

I have a masonry room, South facing with very tall, glazed South wall.
I had forgotten about nighttime window insulation. What are good
materials to use for this, insulated curtains maybe. Options:
nontoxic rigid panels put in place each night (not a bad way to go)
or the foil backed flexible, folding insulation panels or rolls.

I just have two cats, one is going a little feral, the other dropped two
successive loads of wolfbait on my bed, right in the middle, wet reeking
pile and sticky sausages, a thoughtful gift, bansihed from the house

That is an option too. I have a roll of sheet copper 4' X 8' plus a
number of 5' X 8' sheets of clear polycarbonate, perfect for glazing
over a box containing the black-painted copper sheet, mounted with
standoffs from the back for house cold air return flow with hot air
moving over the face of the copper into the window; mount it outdoors
against a windowsill, in the window opening. I will mount this in a
masonry room (insulated masonry walls and insulated concrete floor) with
lots of South glazing.
I found a window-mounted air conditioner/heat pump by Amana with a SEER
rating of 10 for $430 - heat pump with resistance heat backup 4 amps
920 watts 8400 BTU heat. This might heat the whole place.
