  1. Chapter 20Cladding with Masonry & Concrete

  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 Backup Wall Construction Details

  5. CMU Backup Wall • Masonry Veneer Details • CMU Backup Wall • Dampproofing • Insulation • Brick & Ties

  6. 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

  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)

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

  15. Thin Stone Facings Incorporated into Curtain Wall Mullions

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

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

  18. Precast Concrete Panels

  19. Ceramic Tile Facing On Precast Concrete

  20. 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

  21. 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

  22. Exterior Insulation & Finish System (EIFS)

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

  24. EIFS Applications multitude of textures and colors

  25. 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)
