Google says ventilation ducts in Florida last 15 -20 years.
Anyone know anything about this, especially wrapping the ducts in foil?
Thanks

Radiant barriers in attics may be a viable strategy for reducing cooling loads in hot climates. However, that reduction is limited to solar gain from the attic—about 22% of a home’s cooling load. So even though research has found that radiant barriers can deflect 40% of incoming attic heat, the net savings represents about 8% to 10% of a home’s total cooling costs.
