Curtain Wall Design And Selection
Settings
.
- 1.The two major categories of all curtain wall systems are:
- A.
A.Storefront Systems and Window Wall Systems
- B.
B.Fabrication Systems and Stick Systems
- C.
C.Stick Systems and Unitized Systems
- D.
D.Thermally Broken Systems and Thermally Improved Systems
- 2.Stick systems arrive at the project site:
- A.
A. Assembled in pre-built modules
- B.
B. Broken down into individual components
- C.
C. In units on a truck ready to be set in place
- D.
D. Ready to be fabricated and prepped for installation
- 3.An SSG (Structural Silicon Glazed) curtain wall has which main features:
- A.
A. Concealed sightline operable windows
- B.
B.Can be thermally broken
- C.
C. It is fabricated with screw splines attached to shear blocks
- D.
D. Utilizes silicone to secure the glass and as a weather seal on the exterior instead of a pressure plate and cover
- 4.A major advantage of a Unitized system over a Stick System is:
- A.
A. Being in modules it requires less space at the project site for staging
- B.
B. Modules erected in close sequence can enclose a building quickly
- C.
C. Most of the labor is conducted in a shop environment where rates are less
- D.
D. All of the above
- 5.4-Sided SSG curtain wall systems have which main features?
- A.
A. All covers are custom giving it a one-of-a-kind look
- B.
B. Exterior glass surface is flush with no projecting pressure plates of covers from the interior mullions
- C.
C. Glass appears stacked with spider connections between them
- D.
D. Tempered glass units can be secured with tensioned cables behind them
- 6.Which of the following is not a force that can move water?
- A.
A. Pressure Differential
- B.
B. Kinetic
- C.
C. Seismic
- D.
D. Capillary
- 7.The Design Principle of "Pressure Equalization" is:
- A.
A. Balancing the air around each light of glass with the adjacent outside air pressure so that it can weep
- B.
B. Balancing the air space in the insulated glass unit with the interior air pressure
- C.
C. Balancing air space around each light of glass with the interior to reduce pressure differential
- D.
D. All of the above
- 8.The covers on a curtain wall function as a "Rain Screen" which provides which benefit:
- A.
A. Diverts cascading water from reaching critical joints by serving as a capillary break
- B.
B. Prevents wind pressure from forcing water back in the weeps and into the system
- C.
C. The baffle effect shields weeps allowing the system to pressure equalize and weep moisture
- D.
D. All the above
- 9.New "product specific testing" is more likely to be required for which level of curtain wall modification?
- A.
A. Custom project specific system
- B.
B. Standard curtain wall system
- C.
C. Modified curtain wall system
- D.
D. All the above
- 10.Which of the following is not an example of a typical methof of anchoring a curtain wall system?
- A.
A. Edge Angle
- B.
B. Embed Unistrut
- C.
C. Expansion Sleeve
- D.
D. Top of Slab Angle
