One thing I have done last winter and last week is cover the 3 vents in the roof with ~50mm foam insulation (from mail-order pastrami shipments for example). Last winter I used duct tape but that left marks on the paint, so now I use Velcro.
Last winter in December I noticed the snow would quickly melt off the vent covers before I did this, when using the aircraft heaters, even though they are controlled at 5C. The ceiling and walls are 0.44W/sq m-deg K (R-13), windows double pane and metallized shades, but the vents are a single thickness of plastic. Up high where heat collects.
