Point-Supported Glass Curtain Wall System

The point-supported glass curtain wall system creates a transparent facade with minimal visible framing. Glass panels are mechanically fixed with stainless steel point fittings and coordinated with a steel frame, glass fin, truss, or cable-supported structure. The system is ideal for projects that require abundant daylight, open interior visibility, and a refined architectural facade for public and commercial spaces.

Core Advantages

  • Minimal-frame facade appearance with high transparency and a clean structural glass aesthetic.
  • Large glass panels maximize daylight and maintain a clear visual connection between indoor and outdoor spaces.
  • Stainless steel point fittings provide a precise architectural detail and a durable connection system.
  • Tempered laminated safety glass options support strength, impact resistance, and safer post-breakage behavior.
  • The support structure can be engineered with steel frames, trusses, glass fins, or cable-supported solutions to suit the building design.
  • Suitable for entrance walls, atriums, lobbies, stair halls, showrooms, and high-visibility commercial facades.

System Features

  • Point-fixed glass panels reduce the need for traditional mullion framing and create an open, lightweight facade effect.
  • Bolted fittings, rotules, spider connectors, brackets, and structural supports can be selected according to project load and facade layout.
  • Glass joints can be sealed with weather-resistant structural silicone to support a neat, continuous surface.
  • Panel dimensions, fitting spacing, glass thickness, edge processing, and support details are developed according to project engineering requirements.
  • The system can be paired with entrance doors, skylights, railings, and other glass facade components for a coordinated architectural package.

Material and Performance

  • The glass build-up is selected according to facade height, panel size, wind load, safety requirement, thermal target, acoustic requirement, and local building standard.
  • Tempered laminated glass is widely used for point-supported facades because it combines strength with improved retention after breakage.
  • Stainless steel fittings provide corrosion resistance and a refined technical appearance for exterior and semi-exterior facade conditions.
  • Accurate factory drilling, edge processing, fitting alignment, and installation tolerance control are essential for long-term facade performance.
  • Drainage, sealant joints, structural movement, and connection interfaces are coordinated during shop drawing and engineering development.

Customization Options

  • Glass thickness, color, coating, lamination type, frit pattern, and insulated glass configuration.
  • Point fitting model, spider connector shape, stainless steel grade, and visible hardware finish.
  • Support structure type, bracket layout, glass panel size, joint width, and facade grid pattern.
  • Integration with doors, canopy glazing, skylights, railings, and adjacent curtain wall systems.
  • Export packaging method for glass panels, fittings, brackets, and structural facade accessories.

Application Areas

  • Commercial building entrance facades and public lobby walls.

FAQ

Q: Is this system suitable for public buildings?
A: Yes. With engineered support structures and suitable safety glass, point-supported glass curtain walls are suitable for public and commercial facade applications.

Q: Can the facade layout be customized?
A: Yes. Glass panel size, fitting spacing, support structure, joint design, and hardware selection can be customized according to project drawings.

Q: What glass is commonly used?
A: Tempered laminated safety glass is commonly used. Insulated glass, Low-E glass, tinted glass, fritted glass, and customized glazing options are also available.

Q: Can the hardware be selected for coastal environments?
A: Yes. Stainless steel 316 hardware can be specified for coastal or highly corrosive environments, depending on project requirements.
