Answer 1

"Articulated" is not a common glass curtain wall system.

Whereas rest all are the common glass curtain wall system.Curtain walls can adopt a 'stick' system, or can be unitised:

• Stick systems are installed piece by piece on site, with the glazing inserted into the frame from the inside or the outside depending on access conditions.
• Unitised systems are pre-fabricated in modules off-site and delivered in panels. Unitised systems are better able to exploit the benefits of factory condition manufacturing and quality control and require lower installation time on site.

There are a wide range of possible infill panels for curtain wall systems, including:

• Vision glass (which may be double or triple glazed, may include low-e coatings, reflective coatings and so on).
• Spandrel (non-vision) glass.
• Aluminium or other metals.
• Stone or brick veneer.
• Terracotta.
• Fibre-reinforced plastic (FRP).
• Louvres or vents.

Panels are often composites, with the facing materials bonded to, or 'sandwiching' an insulated core such as polyethylene (PE) or polyurethane (PUR), a profiled metal core or a mineral core. See Metal composite panels for more information.
