Any thoughts on what I can do?

If this is the wrong thread i'm sorry, i'm still kimda new.. Anyways I'm building a 4 tier display rack with malamine and plexiglass... My idea is pretty good I just need some help on the best way to heat the display. Any ideas? Is it as easy as cutting vent holes and running a heater from the bottom and allowing the heat to rise? Or will heat tape/ flexwatt warm through the malamine? :confused:

A pic of your design or a pic of it would help...I cant quite picture it from your description

I have PVC cages that are 1/2" thick. I use 11" flexwatt connected to a thermostat to heat them.

Racks are can be complex to heat typically the simple solution is to heat the racks location to the cool/ambient temps and then just provide a hot spot. (room temp of 80 or so and hot spot 90) The best way to heat a rack will alter drastically if the rack was to be in a cool room.
