What is the minimum thickness of shield plates above sole plates for piping installed through notches?

The minimum thickness of shield plates above sole plates for piping installed through notches is specified as 2 inches to ensure adequate protection and support for the piping. This thickness is essential because it provides sufficient strength to safeguard both the piping and the structure above it.

Piping can create stress on the surrounding materials, and the shield plate acts as a protective barrier that distributes this stress evenly. Without an adequate thickness of shield plate, there is a risk of structural integrity being compromised, which could lead to potential failures or damage over time. By adhering to the 2-inch requirement, professionals ensure that the installation meets safety and durability standards, thereby complying with best practices in plumbing installations.
