Our sensation of warmth is
determined by the temeperature of the walls not the air in the room.

Not quite. How warm people feel depends on a number of factors which
do include radiation from objects (including walls) but also include
air temperature, air velocity, the occupants themselves and what
they are doing.

When you insulate, the temperature of the walls goes up and very
likely you can have a lower room air temperature and still feel warm.

That is indeed a factor in lower air temperatures being possible
without affecting comfort..
