A curtain wall system is a specialized type of cladding typically used in the construction of
commercial and institutional buildings. It utilizes glass, either transparent or spandrel or both, and vertical and horizontal mullions acting as structural members to transfer wind and gravity forces to the building structure. The spandrel portion can be metal panel or some other material. There are two types of curtain wall systems – the stick system and the unitized system
A Stick System is a curtain wall system in which the mullions are installed first, and then the glass panels are inserted into the mullion framing in the field. The vertical deflection criteria are more stringent for this type of system than a unitized system. The primary advantage of this system is its lower cost when compared to the unitized system.
A unitized system is a curtain wall system in which the mullions are fabricated with the glass panels in place, and then erected as individual panels. The advantages of the unitized system are firstly that the erection time is reduced, and secondly Unitized panels can tolerate more vertical deflection in the structure due to their gasketed joints. The gasketed joints also allow the curtain wall to form an incremental expansion joint at each mullion which in turn provides for almost unlimited adjustment.
Here are some of the curtain walling systems offered by Pro Aluminium:
SheerWall CW60 – Vistawall Curtain Walling System
VistaWall is widely-used, efficient and time tested curtain wall pressure glazed system for commercial facades that offers you unlimited creative freedom. Vista Wall is designed to allow maximum light into a building by its slim 60 mm sightlines. The diversity of mullion and transoms depth allows you to build according to any standards. The cascade drainage system added to pressure equilibrium in the profiles makes VistaWall highly waterproof.
SheerWall CW90 – Flush Glazed Curtain Walling System
SheerWall CW90 system can be used to create almost perfectly flush-fitted glass façades. The appearance of structural glazing is achieved by using profiles that are only visible on the room side. From the outside, only the glazing and the slender shadow joints are visible. The system can be used for façades of all sizes. SheerWall CW90 is a structural sealant glazing system designed for use in commercial applications.
SheerWall CW120 – Unitized Curtain Walling System
SheerWall CW120 system is a unitized system in which the mullions are fabricated with the glass panels in place, and then erected as individual panels. The biggest advantages of SheerWall CW120 are that the curtain wall erection time on site is drastically reduced and SheerWall CW120 can tolerate more vertical deflection in the structure due to their “gasketed” joints. The “gasketed” joints also allow the curtain-wall to form an incremental expansion joint at each mullion which in turn provides for almost unlimited adjustment.
SheerWall CW70 – Flush glaze Vista Wall with horizontal and vertical line options
Built on the proven success of Sheerline’s Vista Wall curtain wall which set the standards for curtain wall engineering, SheerWall CW70 provides reliability with versatile features. SheerWall CW70 is a stick fabricated, flush glazed curtain wall for low to high-rise applications and is designed to provide different visual impacts with its horizontal line or vertical line options. SheerWall CW70 is suitable for almost any type of building.
