    Aluminium extrusion structure:

    The aluminium extrusion frame is a unitized curtain wall, each panel is an independent unit block and can be designed as unit panels with different widths and heights according to different positions. The unit panel is processed and assembled by the factory, and then sent to the construction site to complete the installation through the docking of the male and female mullion. The unit panel is easy to be hoisted on the construction site, the installation speed is faster, the sealing and waterproof performance is better and the wind and shock resistance is stronger.

    Structure sealant: GE Structure sealant (can be customized)

    Gasket: EPDM or Slicone gasket 

    Glass: Double glazing insluating glass 6HS+12Ar+8FT with double glazing IGU laminated glass 6HS+12Ar+5HS+1.52PVB+5HS using high-quality float glass raw glass sheet, glass color and processing method can be customized).

    Another option with curtain walls is selecting a unitized or stick system. In a stick system, the curtain-wall frame (mullions) and glass or opaque panels are installed and connected together piece by piece. In the unitized system, the curtain wall is composed of large units that are assembled and glazed in the factory, shipped to the site, and erected on the building. Vertical and horizontal mullions of the modules mate together with the adjoining modules. Modules are generally constructed one story tall and one module wide but may incorporate multiple modules. Typical units are 5–6 feet wide. According to Ignacio Fernandez Sola, associate director, Arup, who writes in a LinkedIn article “Unitized vs. Stick: When and Why,” the main variables include the total facade size, degree of repetition, shape and dimensions, planarity, and allowance for structural movement.


    Facade size: The larger the size, the more suitable option is unitized. Giving a rule of thumb, Sola advises unitized for more than 5,000 square meters, and stick if the facade is less than 3,000 square meters, as there isn’t not enough space to achieve the economy of scale to justify unitized.

    Degree of repetition: If the floor height is constant and the distance between mullions is repetitive, then breaking the facade into units of a similar size—as is the case with unitization—and prefabricating them in the factory makes sense.


    Shape and dimensions: Taller buildings above six floors are more suitable for unitized systems, but a low, extended building is a better fit for stick.


    Planarity: If dealing with flat, vertical walls, the on-site assembly of a stick system will be best. But once slope, three-dimensional slopes, and the like are added, the preference shifts to unitized. According to Sola, the same applies for penetrations. The more brackets required for external sunshades, for instance, the more prefabrication is favored.


    Allowance for structural movements: If the project is in a seismic zone and/or if shear or floor-to-floor movements are to be expected, then the ideal choice is unitized.

    Glass Selection


    In order to improve the thermal performance of the glass units in the facade, double or triple glazing is recommended.

    With double-glazed technology, an inert gas is encapsulated in between the two glass panes. The argon allows sunlight to pass through while limiting the level of solar energy that escapes from the glass.

    In a triple-glazed configuration, there are two argon-filled cavities inside three panes of glass. The result is better energy efficiency and sound reduction along with less condensation, as there is a smaller temperature differential between the interior and the glass. While higher performing, triple glazing is a more expensive option.

    For enhanced durability, laminated glass is made with a polyvinyl butyral (PVB) interlayer. Laminated glass offers a number of benefits, including blocking ultraviolet-light transmission, better acoustics, and perhaps most notably, holding together when shattered.

    Segueing into the issue of building impact and blast resistance, the building exterior functions as the first line of defense against projectiles. Consequently, the way the facade responds to an impact will significantly affect what happens to the structure. Granted, it’s difficult to prevent the glass from breaking after a significant impact, but laminated glass, or an anti-shatter film applied to existing glazing, will better contain the shards of glass to protect building occupants from the debris.

    But more than just containing the shattered glass, curtain-wall performance in response to to a blast is dependent upon the interaction between the capacities of the various elements.

    “In addition to hardening the individual members that comprise the curtain-wall system, the attachments to the floor slabs or spandrel beams require special attention,” writes Robert Smilowitz, Ph.D., SECB, F.SEI, senior principal, Protective Design & Security, Thornton Tomasetti – Weidlinger, New York, in WBDG’s “Designing Buildings to Resist Explosive Threats.”

    “These connections must be adjustable to compensate for the fabrication tolerances and accommodate the differential inter-story drifts and thermal deformations as well as be designed to transfer gravity loads, wind loads, and blast loads,” he writes.

    Thermal Performance


    While the roles of the building enclosure are varied and many, the facade’s thermal performance levels loom large in today’s environment of sustainable designs and increasingly stringent codes and standards. Traditionally, glass has been the weak link in the chain, notably decreasing the facade’s overall insulating R-values, no matter how well insulated the other cladding and connecting elements.

    “Heat loss and heat gain through large areas of glazing are some of the more significant performance challenges, particularly in high-altitude and alpine climates, along with controlling glare,” states McGowan. Consequently, high-quality thermal breaks, which work to eliminate the thermal bridges through which cooling and heating energy freely pass, are absolutely essential.

    FAQ

    


    1Q: What’s the Unitized curtain walls?

    A: Unitized curtainwalls are factory-assembled and -glazed, then shipped to the job site in units that are typically one lite wide by one floor tall.

    Unitized curtain walls have become the preferred method for enclosing buildings, as more building owners, architects and contractors see the benefits of this type of construction. Unitized systems allow buildings to be enclosed quickly, which can help to speed up the construction process leading to earlier occupation. The fabrication process for unitized systems is more consistent than for stick-built curtain walls, as unitized wall systems are constructed in almost an assembly line fashion, indoors, and under controlled environmental conditions.

    2Q: What’s the alignment of unitized curtain wall?

    A: There are two types of alignment conditions that must be considered with unitized curtain wall construction.The first one is alignment between unitized panel and the second one is alignment between unitized panels and projecting slabs, canopies and other offsetting structural features of a building.

    Curtain wall manufacturers have reliably dealt with the issue of panel-to-panel alignment by developing structural alignment clips that can be slid across the interlocking heads of adjoining panels to maintain horizontal alignment and by refining the designs of their lifting lugs that help to hold the vertical alignment between panels at their stack conditions. The alignment challenges that manufacturers now face are the unique project-specific building features that interfere with typical panel alignments and must be dealt with on a project-by-project basis.

    3Q: What is the difference between stick and unitised curtain walling?

    A: In a stick system, the curtain-wall frame (mullions) and glass or opaque panels are installed and connected together piece by piece. In the unitized system, the curtain wall is composed of large units that are assembled and glazed in the factory, shipped to the site, and erected on the building.

    4Q: What is a curtain wall Backpan?

    A: Aluminum shadowbox back pans are painted aluminum metal sheets that are attached to the curtain wall framing behind opaque areas of a curtain wall. ​Insulation should be installed between the aluminum shadowbox back pan and the exterior cladding to acts as an air and vapor barrier.
