Compartment heat: Frunk and Gear Tunnel

[shumdit]

This is going to be convective, not radiated, heat so reflective material isn't going to do you much good. You need insulation. ARB has jackets that slip over their portable refrigerators. You will need something like that.

If you are thinking of taking the frunk tub out and fastening insulation to it I wouldn't do that as it might interfere with the condenser air flow increasing compressor head pressure.

No you are not thinking of the correct material. This is a very thin sheet 18x18 that has a reflective barrier and a layer of woven silica with an adhesive backing. I’ve used this product on some builds for off road vehicles and it works well. I will happily provide readings before and after if my truck ever gets built?

Thanks for the data point. You're using an infrared thermometer which measures the surface temperature of whatever you're pointing it at. It's helpful but an ambient air thermometer data would be more useful. I'm assuming the air temp would get quite a bit higher than 95 degrees in there, maybe by about 10-15 degrees.

I wasn't thinking of any material. If the silica layer lends your material an effective R number then it may be suitable but the reflective layer will be useless.

Any object that has been in there for a couple of hours would be in equilibrium with the air.
