I'm having trouble picking out a rack to buy for my kenyan sand boas. I keep getting more and I'm starting to need a rack to house them all.

However, my house in the winter is not kept very warm, it stays at about 62-64 degrees F. My particular kenyans like it hot, with a hot spot of 98-100 F, when I bought new heat pads this year and turned it down to 95 my kenyans actually stopped eating even though their cool end wasn't too cold either.

So, I need some kind of rack system that can handle the heat without melting. Is that even possible? Or should I just try and figure something out with glass? Any ideas on what I should do?
