I'm making a rack with melamine. I've done this in the past with using all melamine (sides/back and all) but it's way too heavy for my taste. I was thinking of using laminate hardboard for the sides but I don't know if the back will hold up to the heat. Since I don't have enough snakes/money to heat a whole room, I use belly and back heat to get the perfect all around temps. What would you all suggest for getting the least weight and being able to handle the heat of flexwatt. I'm guessing most things could take the heat since i'll of course be using a thermostat. Any advice helps and is welcome!
