I have an RV style furnace under my couch with silver ducting it gets pretty warm under there, I want to cover the ducting with a batt to lessen the chance of the limit switch being thrown by drawing in too hot of an air.
Also standing on my step well I can see the outdoors though the shut off valve access vent door thing for the front heater the batt will come in contact with engine coolent heat 210 degrees tops
