Flexwatt when regulated by a good thermostat doesn't need an air gap. I tape the flexwatt to the bottom of my cages then they stack right on top of each other. The thermostat probe goes in a slot on the bottom of the cage like this





But if you want to have a gap in between the cages You could use anything from little rubber feet to pieces of the cage material to raise it up.
