Though it is nice to look through a Plexiglass box, it is 
not a very good thermal performer.  you can buy a 4 by 8 
foot sheet of foam insulation form any builder's supply, 
including possibly one that has a foil surface.  This can be 
cut into rectangles and fit together into a very light 
weight and thermally insulating box for a fraction of the 
cost of a Plexiglass one.

Add a night light or other small heat source to the top, 
inside, to stratify the temperature inside the box, to 
suppress convection currents at night, when the floor is 
warmer than the air.
