2. Masonry & Concrete Cladding Materials
Brick Masonry
Stone Masonry
Cut Stone Panels
Precast Concrete
Exterior Insulation & Finish System

3. Masonry Veneer Curtain Walls
Structural
Backup Wall
Shelf Angle
Anchored to Structure
Every Floor
Supports Brick Veneer
“Soft” Joint
Allows for movement
Structure Creep
Brick Expansion
Beam deflection
Erection tolerances

4. Metal Stud

CMU Backup Wall
Dampproofing
Insulation
Brick & Ties

6. Metal Stud Backup Wall Advantages vs. CMU Disadvantages vs. CMU
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

7. Masonry Veneer Anchors

8. Steel Masonry Support System

9. Prefabricated Brick Wall Panels

10. Prefabricated Brick Soffit Panels

11. Stone Panels Mounted on a Steel Subframe Considerations
Non-structural “interior” Backup Wall needed
System Integrity depends on Joint Sealant

12. 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

13. Stone Facing (granite & limestone)

15. Stone Cladding on Trusses
Thin sheets of Stone
Attached to steel trusses
Set like “panels”
Posttensioned
Limestone
Panels

16. Thin Stone Facings
Incorporated into
Curtain Wall Mullions

17. Thin Stone Facings
Used in Conjunction w/
Exterior Storefront

18. Thin Stone Facings Cast into (attached to) Precast Concrete Panels
Architectural
Precast
Concrete
Precast
Concrete w/
Granite
Facing

19. Precast Concrete Panels
Conventional or prestressed, high quality molds/forms, sandwiched
insulation, multiple finishes and/or application of stone, tile, brick, …..

20. Ceramic Tile Facing
On Precast Concrete

21. 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

22. Exterior Insulation & Finish System - EIFS
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

23. Exterior Insulation & Finish System (EIFS)

24. EIFS Metal Stud Support Application of Insulation
Base coat with reinforcing mesh
Finished Application

25. multitude of textures and colors
EIFS Applications
multitude of textures and colors

26. EIFS Advantages Disadvantages
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)
