What is the minimum gauge sheet steel required for insulation shields around vents passing through insulated assemblies?

The minimum gauge sheet steel required for insulation shields around vents passing through insulated assemblies is 26 gauge. This gauge is specified to provide adequate protection and durability in applications where vents must pass through insulated areas. The use of 26 gauge ensures that the shields can withstand temperature variations, physical impact, and the corrosive elements that might be present in the environment.

Selecting a gauge that is too thin may result in structural weakness, leading to potential failures in protecting the insulation from heat loss or exposure to the elements. In contrast, using a thicker gauge could add unnecessary weight and cost without providing significant added benefits, which is why 26 gauge strikes the right balance for functional performance in insulation shield applications.
