Glass curtain wall
Glass curtain walls are one of the most popular architectural solutions for modern commercial and high-rise buildings. These systems offer an elegant, lightweight, and energy-efficient alternative to traditional masonry facades. Our glass curtain walls are designed to meet international standards while providing durability, thermal efficiency, and aesthetic appeal.

Glass Curtain Wall FAQ
What maintenance do glass curtain walls require?
Glass curtain walls require minimal maintenance compared to traditional facades. Routine cleaning of glass surfaces with mild detergent and soft cloth is recommended. The aluminum frames should be inspected annually for sealant integrity and cleaned with pH-neutral cleaners. Most systems are designed for easy replacement of individual glass panels if needed.
How energy efficient are glass curtain walls?
Modern glass curtain walls can be highly energy efficient when properly specified. Using double or triple glazing with Low-E coatings and argon gas filling significantly reduces heat transfer. Thermal breaks in aluminum frames further improve performance. Our systems can achieve U-values as low as 0.25 W/(m²·K), comparable to many opaque wall systems.
Available Glass Options
Our glass curtain walls can be customized with various glass types to meet specific project requirements:
- Tinted Glass: Reduces solar heat gain and glare
- Reflective Glass: Enhances privacy while maintaining views
- Patterned Glass: Provides diffused light transmission
- Self-Cleaning Glass: Reduces maintenance requirements
- Switchable Glass: Can change from transparent to opaque electronically

Glass Curtain Wall FAQ
What is the typical lifespan of a glass curtain wall system?
A properly installed and maintained glass curtain wall system typically lasts 30-50 years. The aluminum frames have excellent corrosion resistance, especially when powder coated. Glass components may need replacement after 20-30 years depending on exposure conditions. Sealants typically require inspection after 10-15 years and may need partial replacement to maintain weather tightness.
Can glass curtain walls be installed in seismic zones?
Yes, our glass curtain walls are engineered to accommodate seismic movement. Special framing systems allow for up to 100mm of inter-story drift while maintaining weather tightness. The glass is secured using structural silicone or mechanical restraints that permit movement. We can customize designs to meet the specific seismic requirements of your region.
Installation Process
Our glass curtain walls are installed by certified professionals following these key steps:
- Structural analysis and anchor point verification
- Precise installation of aluminum mullions and transoms
- Careful placement and securing of glass panels
- Application of high-performance silicone sealants
- Final inspection and performance testing
Glass Curtain Wall FAQ
How do glass curtain walls handle thermal expansion?
Glass curtain walls are designed with expansion joints and sliding connections to accommodate thermal movement. Aluminum frames expand about twice as much as glass with temperature changes. Our systems use thermal breaks and expansion joints that allow for this differential movement without causing stress or compromising the weather seal. Typically, 1-2mm of clearance per meter is allowed for expansion in each direction.
Customization Options
Our glass curtain walls can be tailored to your project's unique requirements:
- Frame Finishes: Anodized, powder-coated, or woodgrain finishes in various colors
- Glass Coatings: Solar control, low-emissivity, or decorative frit patterns
- Special Shapes: Curved, angled, or custom geometric configurations
- Integration: Compatibility with windows, vents, and other facade elements
- Smart Features: Integration with building automation systems
