TL;DR
A friction surface, in lead-paint regulation, is any painted surface that rubs against another during normal use — window sashes against jambs, door edges against frames, stair treads underfoot — grinding lead paint into the fine dust that poisons children long before paint visibly fails. EPA and HUD rules treat these surfaces specially: encapsulants are prohibited on them, and abatement means component replacement, planing to bare wood, or installing friction-eliminating channels.

Risk assessments sample dust at windows precisely because sash friction concentrates hazard there.
