Backup Wall
Masonry Veneer Details
•CMU Backup Wall
•Dampproofing
•Insulation
•Brick & Ties
Metal Stud Backup Wall
•Metal Studs
•Exterior Gypsum Sheathing
•Insulation
•Attachment of Interior Finishes
Advantages vs. CMU
•Lighter
•Insert Insulation, RI
•Attachment of interior Finishes
Disadvantages vs. CMU
•Typically Less Rigid (lateral resistance)
•Susceptible to moisture damage
Shelf Angle
•Anchored to Structure
•“Hung” from the floor
Masonry Veneer Anchors
Steel Masonry Support System
Prefabricated Brick Wall Panels
Prefabricated Brick Soffit Panels
Stone Panels Mounted
on a
Steel Subframe
Considerations
•Non-structural “interior” Backup Wall needed
•System Integrity depends on Joint Sealant
Monolithic Stone Cladding
Stone panels fastened direct to
the structure
Bolted, or welded attachment
Angle bracing
Sealant required to seal joints
Non-structural backup wall req’d
Stone Facing (granite & limestone)
Stone Cladding on Trusses
•Thin sheets of Stone
•Attached to steel trusses
•Set like “panels”
Posttensioned
Limestone

On Precast Concrete
Glass-Fiber-Reinforced Concrete (GRFC)
Reinforced with Glass Fibers
Support System - often metal framing
Light (easy to mount, less structural load)
Extensive range of colors, textures, shapes
Exterior Insulation & Finish System - EIFS
System:
Foam Insulation adhered or fastened to a Backup
wall (typically metal studs with gypsum sheathing or CMU)
 Up to 4” thick; prevent ‘thermal’ bridging & permits articulation
Base coat(s) of stucco like material with
reinforcing mesh
Exterior Finish coat of a stucco-like material
Appearance like stucco
Exterior Insulation & Finish System (EIFS)
EIFS
Metal Stud Support
Application of Insulation
Base coat with reinforcing mesh
Finished Application
EIFS Applications
multitude of textures and colors
EIFS
Advantages
Can be applied to steel framing, conc., CMU...
Light system, insulation value
Economical, easy to install
Multiple finishes, textures/patterns, colors
Disadvantages
Designed as a barrier system - leakage damage
 Solution – development of an internal drainage system with EIFS
Easily damaged (additional reinforcing mesh to counteract)
