Reptile Shed Conversion

[MKeim1989]

Hello all. I'm going to be moving back to my folks house soon and (as they're terified of snakes) it seems I'll be converting their 22'X12'X10' (8' walls, 4' celing) shed into a "snake shack." At any rate, I'm wondering if anyone has ever tackled such a project and has any advice?

I also have a few questions:

1. Any ideas on how to insulate the floor from the inside? The shed has been there for about six years and was never insulated so I can't go at it from the bottom.

2. In the summer time, is there any way to cool the shed if the temps should go insanely high? I plan on installing a vent fan but I'm afraid it won't be enough.

3. I'm pretty sure we've got the insulation of the walls figured out but I'm open to hear what you've used and your results.

Please lend any advice you can. I want to get this thing done as soon as I can so I can trouble shoot long before I move everyone in.

Thanks in advance!
