Wife and I attended a seminar at a home demonstration on
attic wrapping an attic with a space age vented foil laid over the insulation to keep the heat from the attic off our ceilings in the house.

Also, they talk about wrapping that same vented foil around our ventilation ducts, in the attic and water heater.

Google says ventilation ducts in Florida last 15 -20 years.

Anyone know anything about this, especially wrapping the ducts in foil?

Thanks
