Will the WarehouseFoil® aluminum radiant barrier oxidize & show signs of corrosion over time?

In short, NO. When aluminum reacts with oxygen in the air, it produces an organic aluminum-oxide barrier via a process called passivation. This layer protects the metal’s surface from oxidizing and therefore the product will resist corrosion. Additionally, this protective layer does nothing to diminish the foil’s ability to reflect radiant heat so you have a superior heat barrier that will stand the test of time.
