1 TRANSLANTIC FACADE GAMES EUROPE VS. AMERICA IN THE CURTAINWALL WORLD CUP Gerd Hönicke, Director Pre-Construction Services 1

2 TEAM STATUS AMERICAN UNITIZED FACADES EUROPEAN FACADES = CHICKEN HEAD FACADES = SPIGOT FACADES 2

3 TEAM STATUS Team build American single leg facade (Structural bonded) European façade (structural bonded) American double leg facade (Structural bonded) European façade (captured)

4 TEAM STATUS Team Philosophy American facades = Square cut profiles European façades = Mitered profiles

5 AMERICAN SINGLE LEG FACADE Key components - structural bonded Base transom 2. Head transom 3. Left mullion 4. Right mullion 5. Anti buckling clip 6. Unit joint cover strip 7. Thermal bar 8. Kissing gasket Mullion section Stack joint section 5

6 AMERICAN DOUBLE LEG FACADE Key components Base transom 2. Head transom Left mullion 4. Right mullion 5. Thermal bar 6. Bubble gasket 7. Kissing gasket 7 5 Mullion section Stack joint section 6

7 EUROPEAN FACADE Key components - Captured Head transom 2. Base transom 3. Mullion 4. Cover cap 5. Corner cleat chamber Front chamber 7. Insulation bar Saddle gasket 9. Bubble gasket (part of saddle gasket) 10. Flapper (part of saddle gasket) Coupling gasket Vapor barrier 4 Mullion section Stack joint section 7

8 EUROPEAN FACADE Key components - Structural bonded Base transom Head transom 3. Mullion 2 4. Saddle gasket 5. Coupling gasket 6. Vapor barrier Mullion section Stack joint section 8

9 EUROPEAN FACADES Key components (Structural bonded = Captured) Spigot 2. Corner cleat Hook 4. Bracket Stack joint section Mullion section 9

10 EUROPEAN FACADES Key components (Structural bonded = Captured) Hook Spigot Façade bracket 10

11 EUROPEAN FACADES Frame (Structural bonded = Captured) Unit corners are fabricated using cleats in the same manner as window vents/frames Cleats can be crimped or nailed, and are filled with 2-part adhesive to complete the bonding process A Schueco 4-head crimper is the best crimping machine to use, as it will even out any slight inaccuracies across all 4 corners 11

12 EUROPEAN FACADES Frame (Structural bonded = Captured) Four corner crimper 12

13 AMERICAN SINGLE LEG FACADE Water management and vapor barrier 1 1 One line of defense Mullion section Stack joint section 13

14 AMERICAN DOUBLE LEG FACADE Water management and vapor barrrier 1 One line of defense Mullion section Stack joint section 14

15 AMERICAN FACADE Water management and vapor barrrier 15

16 AMERICAN FACADE Water management and vapor barrrier 16

17 AMERICAN FACADE Water management and vapor barrrier 17

18 EUROPEAN FACADE Water management and vapor barrier st line of defense 2. 2 nd line of defense rd line of defense 4. Vapor barrier 2 1 Mullion section Stack joint section 18

19 EUROPEAN FACADES Water management and vapor barrier Upstand Inner chamber Vapor barrier Coupling gasket Outer chamber Typical cruzi form Insulation bars Bubble gasket Saddle Flapper Cover caps 19 ZAK World of Facades / November 15th 2018 / New York

20 EUROPEAN FACADES Water management and vapor barrier U-shaped saddle gasket Solid unit Vision unit London, Bankside

21 EUROPEAN FACADES Water management and vapor barrier U-shaped saddle gasket Splice joint Splice joint Moulded saddle gasket vision unit solid unit vision unit 21

22 EUROPEAN FACADES Water management and vapor barrier Unitized curved roof 35ft mullion length 8ft unit width London, Tooley Street unit 22

23 EUROPEAN FACADES Water management and vapor barrier Parallelogram shaped units Diagonal length 35ft Unit height 10ft London, 5 Broadgate 23

24 EUROPEAN FACADE Water management and vapor barrier Hoist infill London, Landmark Pinnacle 24

25 AMERICAN FACADES Frame behavior Force direction level-0 level-0 level-0 level-1 direction of force Plane unit unit height unit height Bend unit level-0 unit width level-0 level-0 unit width level-0 25

26 EUROPEAN FACADE Frame behavior Force direction level-0 level-0 level-0 level-1 direction of force Plane unit unit height unit height Bend unit level-0 unit width level-0 level-0 unit width level-0 26

27 AMERICAN AND EUROPEAN FACADES Frame behavior Imposed loads: Wind Temperature change Seismic Cold bend Directions of movements: Vertical In-plane lateral Out-of-plane lateral 27

28 AMERICAN FACADES Frame behavior Vertical movement Caused by floor slab deflection: Units rotate at bracketry Vertical joints no longer parallel, they will become triangular Mullions butting at top 28

29 EUROPEAN FACADE Frame behavior Vertical movements Caused by floor slab deflection: No rotaion of units because of spigot guidance During slab deflection vertical no racking of units Vertical joints remain parallel Units stagger to each other Saddle gasket is compensating staggering effect 29

30 AMERICAN FACADES Frame behavior In plane lateral movement Caused by Wind and Seismic: Units shift at stack joint because chicken head Shear at stackjoint 30

31 EUROPEAN FACADES Frame behavior In-plane lateral movement Caused by Wind and Seismic: Units tilt because guided via spigot Unit load taken at one bracket Racking at stack joint 31

32 AMERICAN AND EUROPEAN FACADES Frame behavior Out-of-plane lateral movement Caused by Wind : Single span unit deflects more than double span unit European Facades deflect less with same profile depth than American Facades American Facades European Facades 32

33 Allowable Capacity (ksi) AMERICAN and EUROPEAN FACADES Frame behavior Out-of-plane lateral movement Capacity of Mullions European facade American double leg facade American single leg facade Unbraced length (in.) 34

34 EUROPEAN FACADES Frame behavior Fly By London, BP 5 35

35 EUROPEAN FACADES Frame behavior GRC Panels London, 5 Mill Street 37

36 AMERICAN DOUBLE LEG FACADE Acoustics Horizontal flanking transmission: Dn,f,w 39dB Mullion section 38

37 EUROPEAN FACADE Acoustics Horizontal flanking transmission: Dn,f,w 46dB Horizontal flanking transmission with infills: Dn,f,w 61dB Mullion section 39
