Penetrations · Orientation and substrate

Why do wall and floor penetrations need different details?

Short answer

Wall and floor penetrations are different orientations with different construction, support and installation conditions. A detail tested in one orientation is not automatically transferable to the other.

What to do next

Send the tag, the schedule reference, the drawings you have and photographs of the actual condition. We will tell you what they show, what they cannot, and what else is needed before anyone gives a conclusion.

General information only. A conclusion about a specific condition requires the actual construction, the evidence behind it and the site condition to be reviewed.
