So I've begun the long journey of building "Cornelius's" enclosure. It's going to be a standard 8x4x4. Here are some photos of it so far: 1. 2. Is this stuff safe, I've heard mixed reports? Couple questions: -Can I nail down the FRP and then just seal it with silicon instead of using liquid nail to adhere it? -I live in Florida, will I still need insulation? The room he/she will be in gets pretty hot to begin with, it sits in the sun all day.
