NOTE: Metal framing, furring and ceiling suspension

systems for lathing are specified in Section 05400

COLD-FORMED METAL FRAMING and Section 09100 METAL

SUPPORT ASSEMBLIES.

NOTE: If discoloration of exterior plaster work

along the lines of the framing system used to

support the lath (metal framing in particular and

wood framing to a lesser extent) occurs or is

anticipated, design the exterior wall with a thermal

break between the metal lath and the framing

members. One suggested solution is to install 12.7

mm 1/2 inch thick gypsum sheathing board, conforming

to ASTM C 79, "Gypsum Sheathing Board," on the

framing members before attaching the metal lath.
