A stick curtain wall system is a non-load-bearing exterior wall assembled on the construction site from individual vertical mullions, horizontal transoms, glass or opaque infill panels, gaskets, pressure plates, caps, anchors, and perimeter seals. The building’s primary structure carries the gravity loads, while the curtain wall transfers its own weight and environmental loads back to the structure through engineered connections. At Jangho, I view a stick curtain wall as a flexible, site-assembled façade solution for commercial buildings where project conditions, access, and customization are important.

Unlike a unitized curtain wall, which arrives in large factory-assembled panels, a stick system is delivered as separate components and installed floor by floor or bay by bay. This approach can support detailed adjustment on site, but it also places greater responsibility on installation sequencing, tolerances, sealing, and quality control. The right choice depends on building height, repetition, schedule, logistics, performance requirements, and the capability of the façade contractor.
A stick curtain wall begins with vertical mullions fixed to floor slabs, beams, or other prepared structural supports. Horizontal transoms are then connected between the mullions to create framed openings for vision glass, spandrel glass, metal panels, stone-look panels, louvers, or other approved infill materials. Glass and panels are retained with pressure plates, snap-on covers, gaskets, setting blocks, fasteners, and compatible sealants.
The system normally transfers wind pressure and suction through the infill and framing into the anchors and then into the building structure. Its joints must accommodate movement caused by thermal expansion, building deflection, manufacturing tolerances, and installation variation. Water management is usually based on drained and pressure-moderated cavities, properly designed weep paths, sealed intersections, and continuous perimeter interfaces.
The exact sequence can change according to the building structure, access equipment, weather, façade geometry, and local regulations. For example, some projects install several floors of vertical mullions before adding transoms, while others complete smaller bays to reduce exposure to weather. I recommend agreeing on the installation sequence during shop drawing coordination rather than leaving it entirely to the site team.
Aluminum is widely used for stick curtain wall framing because it offers a practical balance of weight, corrosion resistance, machinability, and profile flexibility. The visible cap can be selected in different shapes, finishes, and dimensions to support the intended architectural appearance. A thermal break may be incorporated where the design requires improved thermal separation between exterior and interior aluminum surfaces.
Frame depth, wall thickness, alloy selection, finish, and reinforcement should be confirmed through structural and performance calculations. I do not recommend selecting a profile only by appearance because the mullion must respond to span, wind pressure, glass weight, deflection criteria, anchor spacing, and local code requirements. The final section should come from project-specific engineering and approved system details.
Common infill options include insulating glass units, laminated glass, monolithic glass, spandrel glass, insulated metal panels, aluminum panels, and combinations of these materials. The selection affects daylight, solar control, acoustic performance, safety, thermal behavior, weight, and façade appearance. Glass composition should be coordinated with the building’s energy strategy and the required safety provisions.
For early planning, commercial curtain wall grids often use modules approximately 1.2 to 1.5 meters wide and floor-to-floor heights of roughly 3 to 4 meters, but these are indicative planning ranges rather than universal specifications. Actual dimensions depend on structural movement, glass availability, wind loads, transportation, façade rhythm, and installation capability. I use these figures only as starting points before detailed engineering begins.
Gaskets and sealants are not minor accessories; they are central to air, water, and movement control. Materials must be compatible with the aluminum finish, glass edge, setting blocks, insulation, and adjacent façade products. Drainage openings must remain clear, and sealant joints must be designed with appropriate width, depth, backing, adhesion, and movement capability.
These advantages are especially useful when a project has irregular geometry, variable floor conditions, or limited opportunity for large-panel lifting. The system can also be appropriate when the contractor has experienced façade installers and can maintain disciplined quality control. However, flexibility does not remove the need for accurate surveys, approved details, and controlled installation.

Because assembly occurs on site, labor quality and weather exposure can have a stronger effect than with a highly factory-assembled alternative. Repetitive high-rise projects may also face longer installation cycles if every framing and sealing operation must be completed at the building. Site storage, protection, access, lifting plans, and coordination with other trades must therefore be considered during procurement.
A stick curtain wall is not automatically the best solution for every tall or highly repetitive building. Unitized curtain wall may offer stronger factory control and faster floor-by-floor installation when the design, production volume, transportation route, and lifting strategy support it. I recommend comparing both systems against the actual project schedule and façade engineering requirements rather than choosing based on a general industry preference.
Stick systems are commonly evaluated for commercial offices, retail façades, educational buildings, hotels, institutional projects, podiums, entrance elevations, and building renovations. They can be useful when the façade has moderate repetition but still requires local customization around corners, entrances, slab edges, or mixed-material transitions. They are also worth considering when project access makes large prefabricated panels difficult to handle.
For very tall buildings, highly repetitive façades, or projects with severe weather exposure during installation, I examine the benefits and risks more carefully. Wind load, interstory movement, floor deflection, fire and smoke requirements, thermal targets, acoustic expectations, and maintenance access all influence suitability. The final decision should be made through coordinated architectural, structural, façade, and construction planning.
When I help a B2B buyer evaluate a stick curtain wall, I first request the building location, height, floor-to-floor dimensions, façade elevations, glass build-up, design pressures, performance targets, and installation conditions. I also review whether the project requires operable vents, doors, sunshades, louvers, fire stopping, opaque zones, or interfaces with stone, metal, precast, and waterproofing systems. Missing interface information is a common source of redesign and site delay.
| Evaluation Area | Questions to Confirm |
|---|---|
| Structural performance | What are the wind loads, spans, anchor spacing, movement requirements, and deflection criteria? |
| Thermal and weather performance | Are U-value, solar control, air infiltration, water resistance, and condensation requirements defined? |
| Materials and appearance | Which glass, panels, aluminum finish, cap profile, color, and interior finish are required? |
| Installation | Who will install the system, what access is available, and how will components be protected and stored? |
| Documentation | Will the supplier provide shop drawings, calculations, installation guidance, packing lists, and maintenance information? |
I also advise buyers to clarify what is included in the quotation. A complete commercial review should distinguish between framing, glass, panels, anchors, fasteners, gaskets, sealants, thermal isolators, flashing, shop drawings, engineering, packaging, delivery, and technical support. Comparing only the price per square meter can hide important scope differences and create avoidable procurement risk.
At Jangho, I support buyers by organizing project requirements before production planning begins. Our cooperation can cover system selection, profile and infill coordination, shop drawing review, material schedules, finish confirmation, packing organization, and technical communication with the project team. The exact scope depends on the contract, destination market, approved drawings, and responsibilities assigned to the façade contractor.
I believe supplier support should be practical and document-based. Buyers should expect clear drawings, traceable material descriptions, consistent labeling, installation instructions, and timely clarification of unresolved interfaces. Where project specifications require testing or third-party verification, those requirements should be identified in advance and handled through the agreed project procedure rather than assumed.
A stick curtain wall system is a strong candidate when your commercial building needs a customizable façade that can be assembled and adjusted on site. It is particularly suitable when access, building geometry, component delivery, and installer capability favor a piece-by-piece installation method. It may be less suitable when a very tall, repetitive project demands maximum factory assembly and highly accelerated floor-by-floor installation.
My recommended next step is to prepare the elevations, project location, building height, typical bay dimensions, glass requirements, design pressures, movement criteria, performance targets, and installation plan. Send these details to Jangho for a preliminary system review and a clearly defined supply scope. With early coordination, I can help you compare stick curtain wall options against your technical, commercial, and construction requirements before you commit to procurement.
