Hi, sorry for another question, couldn't find answers on google.

Info: New larger glass tank, UTH regulated with thermostat, heat lamp with control dial, 3 sides and 2/3 of the top fully covered in insulation foam, beneath the UTH is ceramic tile. Measuring with heat gun

Previously I had it around 90-92 and that worked perfectly to maintain temps, but in this one even at 95 the temps are a bit low.

There should be no direct access to the glass itself, there is reptile carpet underneath 2-3 inches of substrate. If he really really wanted to, he could probably get under the carpet, but it would be immediately noticeable to me and would require uprooting large decor. So far he's shown no interest in burrowing, but I'm considering buying more ceramic tile to lay on top of the reptile carpet beneath the substrate just in case since I know direct glass contact would be the biggest concern for burns.

Right now with the thermostat set to 95, the absolute warmest reading I can get digging under the substrate is ~85, but most of the warm side is closer to 75-80 with the cool side around 70-75.

My question is, what is the max temp you can safely set the UTH to without risking burns?

Thanks in advance for any advice!
