What is a sheeting?
Sheeting is solid material fixed to the outside of a scaffold to enclose it against weather or contain debris. It substantially increases the wind load the scaffold must resist.

</figure>Sheeting turns an open frame into a sail. Wind that previously passed through the scaffold now pushes against it, and that force has to go somewhere — into the ties, and through them into the building.
This is why sheeting a scaffold is a design change rather than a finishing touch. A structure tied for an open scaffold is under-tied the moment it is sheeted, regardless of how well it was tied before.
Debris netting is the lighter alternative: it contains material while letting more air through, so it increases wind loading less than solid sheeting does.
What goes wrong on site
- Sheeting added during a job without revisiting the tie pattern.
- Sheeting extended by a following trade for weather protection, with nobody told.
- Damaged sheeting left flapping, which loads the scaffold unpredictably.
