Advice for a Melamine Enclosure

I'm building my 7 foot Coastal Carpet Python a new enclosure. I'm making it 36" x 24" x 16".

What are some tips or advice you would give me? I'm specifically looking for heating tips? What do you guys thinking about FlexWatt inside the enclosure covered by plexiglass? Does flexwatt need to "breathe?"

On the melamine 48"x24"x16" I'm building now I put ceramic floor tiles over the flexwatt, it conducts heat nicely.

Nice! So I'm assuming that the flexwatt doesnt need any ventilation?

Nah it'll be fine as long as what ever material it's touching isn't sensitive to what ever heat it's putting out. This setup has been running for over a week now and the electronics are all fine. I'll try to get some pics of what it looks like when I'm done messing with it... its holding humidity a little too well right now lol.
