Those numbers point to the tested configuration, the impact status, the design pressure, and the conditions under which the window can be installed.

How The Number System Works

In practical terms, the approval number is the trail back to the exact window model and the testing record behind it.

This matters because one brand can sell many versions of the same window, and each one may have its own approval record depending on frame material, glass type, size limits, and optional features.
