Heat Transfer

[Pinto2]

I have read through all the old threads about cage building and have learned a hole lot. So much in fact that i have read some stuff that contradicts what others say. So heres my question about heating a cage made of melimine (spelling). IF i have a heating pad underneath the cage, will the heat eventually transfer through it. The cage will be wood on all sides except for the front, where it will be plexie glass. I will be using an UTH and a heat light on the top. For a basking spot. Can some you you guys please share your experiences with me so that i don't make newbie mistakes. Should i stick the heating pad to the wood, or rest in a inch below? The cage will be 5' by 2' by 20'' . Thanks
