Transcription

1 subject CLADDING cladding w/ metal & glass chapter 21 DATE SPRING 2014 professor MONTGOMERY

2 DE-MATERIALIZING BUILDINGS maximum transparency

3 CLADDING W/ METAL & GLASS new notion of skin

4 MAXIMIZING TRANSPARENCY outside in

5 MAXIMIZING TRANSPARENCY inside out

6 this week objective: overview of the materials and method of building metal and glass exterior building skin.! aluminum extrusions thermal breaks aluminum & glass framing systems store fronts curtain walls modes of assembly outside/inside glazing dual layered glass cladding design process PROFESSOR MONTGOMERY

7 Aluminums s properties:! 1. strong 2. light weight 3. conducts heat rapidly 4. high co-efficient of thermal expansion ALUMINUM metal of choice

8 Aluminums s advantages for use in cladding systems:! 1. protects itself against corrosion 2. accepts & holds a variety of attractive surface finishes 3. can be fabricated economically into elaborately detailed shapes ALUMINUM metal of choice

9 ALUMINUM billets

10 ALUMINUM extrusion

11 ALUMINUM thermal break

12 ALUMINUM framing systems

13 framing systems:! two types of systems:! 1. storefront 2. curtain wall FRAMING SYSTEMS types

14 storefront:! 1. simple 2. light 3. less expensive 4. quick to assemble 5. short spans: used on low floors 7. often framed within a masonry opening FRAMING SYSTEMS storefront

15 Curtain wall:! 1. sophisticated 2. high performance 3. more expensive 4. stronger/stiffer 5. resists wind loads 6. resists water penetration 7. longer spans 8. used on high floors FRAMING SYSTEMS curtain wall

16 FRAMING SYSTEMS storefront and curtain wall

17 FRAMING SYSTEMS curtain wall

18 Curtain wall:! usually framed outside of structural frame FRAMING SYSTEMS curtain wall

19 FRAMING SYSTEMS curtain wall

20 FRAMING SYSTEMS curtain wall

21 FRAMING SYSTEMS spandrel panels

22 MODES OF ASSEMBLY stick system

23 MODES OF ASSEMBLY stick system - outside glazed

24 MODES OF ASSEMBLY unit system

25 MODES OF ASSEMBLY unit system

26 MODES OF ASSEMBLY unit system

27 MODES OF ASSEMBLY anchors

28 MODES OF ASSEMBLY anchors

29 two exterior walls advantages:! 1. high performance 2. thermal barrier 3. noise barrier 4. daylight control 5. design freedom INNOVATION dual layered glass cladding

30 two exterior walls disadvantages:! high cost 1. sacrifice of usable space 2. maintenance increase 3. (higher glass area to clean) INNOVATION dual layered glass cladding

31 INNOVATION dual layered glass cladding

32 EXTERIOR WALLS + SCREEN CONTROL DAYLIGHTING AND GLARE REDUCE HEAT GAIN INNOVATION solar shading

33 DESIGN SCENARIOS: 1. SELECT A MANUFACTURER TO ASSIST W/ DESIGN 2. DEFINE PERFORMANCE AND BID TO MULTIPLE MANUFACTURERS 3. CUSTOM DESIGN SYSTEM W/ CURTAIN WALL DESIGN CONSULTANT 4. INSTALLER S INPUT DESIGN PROCESS responsibilities

34 wrap up METAL AND GLASS CLADDING O P E N S T H E B U I L D I N G S I N T E R I O R S T O T H E ENVIRONMENT OUTSIDE AND REDEFINES THE CHARACTER AND NATURE OF THE SKIN ultimate system to achieve goal of transparency fundamental change in the tectonics of buildings systems approach movement and water penetration must be carefully considered performance advantages and disadvantages
