| System | Manufacturing / Installation | Best For | Main Advantage |
| Unitized Curtain Wall | Factory assembled | High-rise / large facade | Installation speed & consistency |
| Stick Curtain Wall | Site assembled | Low-mid rise / complex geometry | Design flexibility |
| Full Glass Curtain Wall | Glass-focused system | Entrances / commercial / landmark | Transparency |
| Aluminum Curtain Wall | Aluminum framing + infill | Commercial facade | Customization & durability |
Curtain wall systems should be engineered to meet project-specific structural, weather, thermal, and glazing requirements. Key considerations include:
Structural & Wind Load
System design is evaluated based on building height, project location, wind pressure, mullion span, glass weight, and connection requirements.
Air & Water Tightness
Proper gaskets, sealants, drainage paths, and pressure-equalized detailing improve resistance to air leakage and water penetration.
Thermal Performance
Thermal-break aluminum profiles, insulated glass units (IGUs), Low-E glazing, and insulated spandrel panels are selected according to climate and energy-performance requirements.
Glass & Infill Options
Available options include tempered glass, laminated glass, insulated glass units (IGUs), Low-E glass, spandrel glass, and aluminum or metal composite panels.
ALTOP delivers full-cycle curtain wall support from technical review and engineering coordination through fabrication, quality assurance, and delivery. Using project drawings and performance specifications, our team develops buildable façade solutions for all building types.
01 Project Review & Design Coordination
We conduct a rigorous pre-production review architectural drawings, façade elevations, system
requirements, dimensions, and key performance specifications, ensuring design-build alignment
and constructability.
02 Engineering & Shop Drawings
We develop and coordinate shop drawings for assemblies, connections, panel sizes, interfaces, and fabrication details, fully aligned with project requirements and standards.
03 Fabrication & Assembly
Under controlled manufacturing procedures, we process aluminum profiles, prepare glass or infills, fabricate components, and assemble unitized or stick-built systems.
04 Quality & Delivery
A comprehensive quality management protocol is implemented across all stages: materials, first-article verification, in-process inspections, sealant integrity, performance testing (air/water, structural), packaging, and on-schedule delivery synced with construction.
ALTOP curtain walls are suitable for office buildings, commercial complexes, hotels, and high-end residential projects.
