Glass Curtain Wall Market Set to Rise as Green Building Practices Gain Momentum

 The global glass curtain wall market is projected to reach USD 67.2 billion by 2025, with an expected CAGR of 7.0% from 2025 to 2030, reaching USD 104.2 billion by the end of the forecast period. The rising emphasis on sustainable construction and energy-efficient building solutions is driving demand for glass curtain wall systems worldwide. These systems, known for their superior insulation capabilities, help minimize heat gain during warmer months and heat loss during cooler periods—resulting in significant reductions in HVAC costs. The adoption of double-glazed and low-emissivity (Low-E) glass continues to grow, aligning with tightening environmental regulations and heightened awareness around green building standards.

End-use Insights

• Commercial Segment: Accounted for 71.6% of revenue in 2024, driven by demand from corporate offices, shopping centers, and hotels. Glass curtain walls are increasingly valued for their energy savings, natural light integration, and architectural appeal.

• Residential Segment: Experiencing rapid growth, particularly in Asia Pacific and the Middle East, as urbanization fuels demand for premium high-rise apartments and smart homes. Glass curtain walls provide both aesthetic enhancement and energy efficiency.

• Market Landscape and Competitive Dynamics

  The market is moderately concentrated, with leading companies such as AGC Inc., Guardian Glass, and Saint-Gobain dominating the competitive landscape. Industry players are heavily investing in smart glazing technologies, thermal insulation coatings, and energy-efficient glass solutions to comply with evolving building codes and environmental regulations like LEED and BREEAM. This regulatory pressure is prompting manufacturers to focus on performance, sustainability, and innovation.

  Despite some competition from substitute materials like aluminum cladding and traditional masonry, glass curtain walls remain unmatched in offering both visual appeal and energy efficiency. Hybrid facades, blending glass with other materials, represent a growing trend, though their adoption remains limited.

  The demand for curtain walls is largely driven by commercial and institutional buildings, including office towers, hospitals, malls, and educational centers. However, the residential sector, especially luxury high-rise developments, is showing notable growth as consumers seek energy-efficient, visually appealing, and well-lit living spaces.

• Technology and Innovation Driving Market Expansion

  Recent technological advancements in glass manufacturing and curtain wall systems are further propelling market growth. Innovations such as photovoltaic (PV) glass, dynamic glazing, and self-cleaning glass are enhancing both the functionality and aesthetics of curtain walls. These materials not only reduce reliance on artificial lighting but also cut down on maintenance costs. Additionally, the emergence of lightweight, high-strength glass has broadened the applicability of curtain wall systems, making them suitable for a wider range of structural designs.

• System Type Insights

  • Unitized Systems: Dominating the market with a 66.9% share in 2024, unitized systems are favored for their factory pre-assembly, faster installation, and high precision. These systems are ideal for large-scale, high-rise developments, where speed and structural integrity are crucial.

  • Stick Systems: Expected to grow at a CAGR of 5.9% from 2025 to 2030, stick systems offer greater design flexibility and cost-effectiveness. Their on-site assembly makes them suitable for projects requiring customization, particularly in smaller buildings or retrofits.
