Masonry & Concrete Cladding Materials

Brick Masonry

Stone Masonry

Cut Stone Panels

Precast Concrete

Exterior Insulation & Finish System

Masonry Veneer Curtain Walls

Shelf Angle•Anchored to Structure•Every Floor•Supports Brick Veneer

“Soft” Joint•Allows for movement

•Structure Creep•Brick Expansion•Beam deflection

•Erection tolerances

CMUBackup Wall

Shelf Angle•Anchored to Structure•“Hung” from the floor

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

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 structureBolted, or welded attachmentAngle 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

Glass-Fiber-Reinforced Concrete (GRFC)

Reinforced with Glass FibersSupport System - often metal framingLight (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

Finished Application

Application of Insulation

Base coat with reinforcing mesh

EIFS

EIFS Applicationsmultitude of textures and colors

EIFS

AdvantagesCan be applied to steel framing, conc., CMU... Light system, insulation valueEconomical, easy to installMultiple finishes, textures/patterns, colors

DisadvantagesDesigned as a barrier system - leakage damage

Solution – development of an internal drainage system with EIFS

Easily damaged (additional reinforcing mesh to counteract)
