4.3 METAL STUD WALLS
Metal stud infill walls are used with a variety of exterior claddings including brick veneer, EIFS (see
Section on EIFS), stucco, metal siding and other lightweight exterior finishes. Figure 4.3.1 shows
the basic elements of a metal stud wall with a brick veneer. There are several advantages to metal
stud walls including speed of erection and low weight. Their use with brick veneers is a relatively
recent development and has been associated with a certain amount of controversy as discussed
below. There is limited guidance on metal stud wall construction, relative to other wall systems.
Some design guidance is provided in a 1981 Design Guide for Insulated Buildings (Owens/Corning
Fiberglas), however the material in this document does not specifically address air leakage control
through the use of air barrier systems. The Canada Mortgage and Housing Corporation (CMHC)
Seminar on Brick Veneer Wall Systems (1989) provides a thorough treatment of brick veneer/metal
stud construction, addressing advantages, disadvantages and making recommendations for the
design and construction of such systems.
