  The two major categories of all curtain wall systems are:

  • A.

    Storefront Systems and Window Wall Systems

  • B.

    Fabrication Systems and Stick Systems

  • C.

    Stick Systems and Unitized Systems

  • D.

    Thermally Broken Systems and Thermally Improved Systems

  Correct Answer

  
  C. Stick Systems and Unitized Systems

  Explanation

  
  Stick systems and unitized systems are the two major categories of all curtain wall systems. Stick systems involve assembling the curtain wall on-site, with individual components such as mullions and glass panels installed separately. This allows for flexibility in design and easier replacement of damaged components. On the other hand, unitized systems are pre-fabricated off-site and installed as complete units. This method offers faster installation and better quality control, but may have limitations in design flexibility and replacement options.

  Stick systems arrive at the project site:

  • A.

    Assembled in pre-built modules

  • B.

    Broken down into individual components

  • C.

    In units on a truck ready to be set in place

  • D.

    Ready to be fabricated and prepped for installation

  Correct Answer

  
  B. Broken down into individual components

  Explanation

  
  The correct answer is "Broken down into individual components." This means that the stick systems are not pre-built or assembled in modules before arriving at the project site. Instead, they are delivered in separate parts or components, which will then be assembled on-site. This allows for more flexibility in installation and customization according to the specific requirements of the project.

  An SSG (Structural Silicon Glazed) curtain wall has which main features:

  • A.

    Concealed sightline operable windows

  • B.

    Can be thermally broken

  • C.

    It is fabricated with screw splines attached to shear blocks

  • D.

    Utilizes silicone to secure the glass and as a weather seal on the exterior instead of a pressure plate and cover

  Correct Answer

  
  D. Utilizes silicone to secure the glass and as a weather seal on the exterior instead of a pressure plate and cover

  Explanation

  
  The main feature of an SSG (Structural Silicon Glazed) curtain wall is that it utilizes silicone to secure the glass and act as a weather seal on the exterior, rather than using a pressure plate and cover. This means that the glass is directly bonded to the structure using silicone, providing a seamless and aesthetically pleasing appearance. Additionally, the use of silicone as a weather seal helps to prevent water infiltration and improve the overall performance of the curtain wall system.

  A major advantage of a Unitized system over a Stick System is:

  • A.

    Being in modules it requires less space at the project site for staging

  • B.

    Modules erected in close sequence can enclose a building quickly

  • C.

    Most of the labor is conducted in a shop environment where rates are less

  • D.

    All of the above

  Correct Answer

  
  D. All of the above

  Explanation

  
  The correct answer is "All of the above". This means that all the advantages mentioned in the options are true for a Unitized system compared to a Stick System. It requires less space at the project site for staging because it comes in modules. Erecting the modules in close sequence allows for a quick enclosure of the building. Additionally, most of the labor is conducted in a shop environment where rates are less.

  Sided SSG curtain wall systems have which main features?

  • A.

    All covers are custom giving it a one-of-a-kind look

  • B.

    Exterior glass surface is flush with no projecting pressure plates of covers from the interior mullions

  • C.

    Glass appears stacked with spider connections between them

  • D.

    Tempered glass units can be secured with tensioned cables behind them

  Correct Answer

  
  B. Exterior glass surface is flush with no projecting pressure plates of covers from the interior mullions

  Explanation

  
  The main feature of sided SSG curtain wall systems is that the exterior glass surface is flush with no projecting pressure plates or covers from the interior mullions. This means that the glass panels appear to be stacked with spider connections between them, giving the system a sleek and seamless look. Additionally, tempered glass units can be secured with tensioned cables behind them, further enhancing the aesthetic appeal and structural integrity of the curtain wall system.

  Which of the following is not a force that can move water?

  • A.

    Pressure Differential

  • For more information, please visit Q-box.

    B.

    Kinetic

  • C.

    Seismic

  • D.

    Capillary

  Correct Answer

  
  C. Seismic

  Explanation

  
  Seismic forces are not capable of directly moving water. Seismic forces refer to the vibrations and movements caused by earthquakes or other geological activities. While seismic forces can cause water to move indirectly by shaking the ground or causing landslides near bodies of water, they do not directly move water like pressure differential, kinetic energy, or capillary action can. Therefore, seismic is the correct answer as it is not a force that can directly move water.

  The Design Principle of "Pressure Equalization" is:

  • A.

    Balancing the air around each light of glass with the adjacent outside air pressure so that it can weep

  • B.

    Balancing the air space in the insulated glass unit with the interior air pressure

  • C.

    Balancing air space around each light of glass with the interior to reduce pressure differential

  • D.

    All of the above

  Correct Answer

  
  A. Balancing the air around each light of glass with the adjacent outside air pressure so that it can weep

  Explanation

  
  The Design Principle of "Pressure Equalization" is balancing the air around each light of glass with the adjacent outside air pressure so that it can weep. This means that the pressure inside the glass is equalized with the pressure outside, allowing any moisture or condensation to escape through small openings or weep holes. This helps to prevent any buildup of pressure or moisture within the glass, ensuring its durability and longevity.

  The covers on a curtain wall function as a "Rain Screen" which provides which benefits:

  • A.

    Diverts cascading water from reaching critical joints by serving as a capillary break

  • B.

    Prevents wind pressure from forcing water back in the weeps and into the system

  • C.

    The baffle effect shields weeps allowing the system to pressure equalize and weep moisture

  • D.

    All the above

  Correct Answer

  
  D. All the above

  Explanation

  
  The covers on a curtain wall function as a "Rain Screen" which provides multiple benefits. Firstly, they divert cascading water from reaching critical joints by serving as a capillary break. This helps to prevent water infiltration and potential damage to the structure. Secondly, they prevent wind pressure from forcing water back into the system through the weeps. This ensures that the water is effectively drained out of the system. Lastly, the covers create a baffle effect that shields the weeps, allowing the system to pressure equalize and weep moisture effectively. Therefore, all of the above benefits are provided by the covers on a curtain wall.

  New "product-specific testing" is more likely to be required for which level of curtain wall modification?

  • A.

    Custom project specific system

  • B.

    Standard curtain wall system

  • C.

    Modified curtain wall system

  • D.

    All the above

  Correct Answer

  
  A. Custom project specific system

  Explanation

  
  Custom project specific system refers to a curtain wall that is specifically designed and engineered for a unique project. This means that it may have different components, configurations, or performance requirements compared to standard or modified curtain wall systems. Therefore, new product-specific testing is more likely to be required for a custom project specific system to ensure that it meets the specific project's requirements and performs as intended.

  Which of the following is not an example of a typical method of anchoring a curtain wall system?

  • A.

    Edge Angle

  • B.

    Embed Unistrut

  • C.

    Expansion Sleeve

  • D.

    Top of Slab Angle

  Correct Answer

  
  C. Expansion Sleeve

  Explanation

  
  Expansion Sleeve is not a typical method of anchoring a curtain wall system. Typically, curtain wall systems are anchored using methods such as edge angle, embed unistrut, and top of slab angle. Expansion sleeves, on the other hand, are typically used for anchoring other types of structures or systems, such as pipes or cables, and are not commonly used for curtain walls.
