Heating for plastic cage in a cold room

[RestlessRobie]

I have some custom built 4X2X1 enclosures that are basically XPVC and wood. I use Flexwatt for belly heat at about 92f. I use the Reptile Basics 40w Radiant Heat panel at 80f and did a little testig before I add the snakes. The temp of my room has to drop below 65f before the Heat Panel has to work above 50% so I think you should be fine. If needed you could add some foambaord insulation around 3 sides this woyuld keep some more heat in but I think you shouls be ok.
