In today’s architecture, tempered glass has become a fundamental component in enhancing both aesthetics and performance of modern buildings. Especially within curtain wall systems, tempered glass contributes not only to visual transparency but also to structural strength, safety, and energy efficiency. As high-rise buildings and complex facades become more common, the demand for durable and versatile glass products grows, placing tempered glass at the center of architectural innovation.
In this article, we explore the structural components and trends of curtain wall systems, the technical advantages of tempered glass, its typical applications, sustainability requirements, and exemplary engineering projects. We also introduce HANGZHOU REACHBUILDING CO., LTD., a reputable tempered glass factory and supplier dedicated to delivering high-quality curtain wall solutions worldwide.
Curtain wall systems are non-load-bearing exterior walls typically made of glass, aluminum, or stone. Their primary function is to shield the building from environmental elements while allowing natural light inside.
Structurally, a curtain wall comprises aluminum frames (mullions and transoms) that support glass panels or other cladding materials. These systems also include insulation layers, vapor barriers, sealants, and gaskets to ensure waterproofing, energy efficiency, and durability under various environmental conditions.
Two major types dominate the curtain wall market: stick-built systems, which are assembled piece by piece on-site, offering flexibility in construction, and unitized systems, which are pre-fabricated in a tempered glass factory for quick installation, enhanced quality control, and better weather resistance.
Recent trends in curtain wall system development emphasize sustainability and innovation. These include double-skin façades for superior thermal insulation, photovoltaic-integrated curtain walls that generate solar power, smart glass for dynamic light control, and parametric designs enabling complex architectural forms.
Tempered glass, also known as toughened glass, undergoes a thermal or chemical process to increase its strength. It is about 4 to 5 times stronger than standard annealed glass of the same thickness.
High Strength:Tempered glass exhibits four to five times the strength of ordinary annealed glass. It resists wind pressure, impact, and mechanical loads, making it ideal for structural use in curtain wall systems.
Safety:Unlike standard glass, tempered glass breaks into small, blunt fragments that are less likely to cause injury. This safety feature is critical in buildings, especially in public areas and high-traffic zones.
Thermal Resistance:Tempered glass can withstand rapid temperature variations up to 250°C without cracking. This makes it suitable for both indoor and outdoor applications where thermal stress is a concern.
Optical Clarity:With visible light transmittance rates between 85% and 90%, tempered glass ensures excellent daylighting. Coating types and glass thickness may affect clarity, but it remains optimal for transparent glass products.
These features make it ideal for large-span curtain walls, skylights, and facades exposed to dynamic weather conditions or mechanical stress.
Tempered glass is widely used across various types of curtain wall configurations:
Supported by stainless steel spider fittings, these systems allow for minimal visible framing. They create sleek, open views ideal for atriums, lobbies, and exhibition halls, emphasizing architectural transparency and design elegance.
These systems are prefabricated with tempered glass panels in a controlled factory environment. Their fast on-site assembly makes them ideal for high-rise commercial towers, office complexes, and upscale hotel façades.
DGUs frequently use tempered glass paired with low-E coatings to enhance thermal insulation. They offer excellent soundproofing, solar control, and energy efficiency, particularly in environmentally conscious and climate-sensitive buildings.
Frameless glass walls feature no visible aluminum mullions, relying solely on the strength of tempered glass. Commonly used in luxury storefronts and showrooms, they provide a clean, modern aesthetic with uninterrupted views.
These installations utilize laminated tempered glass for enhanced overhead safety. Ideal for malls, airports, or atriums, they allow natural light while maintaining protection from falling hazards or accidental breakage.
In all these applications, working with a professional tempered glass factory ensures precise sizing, hole drilling, edge polishing, and coating—critical for system performance and longevity.
As the global architecture community moves towards green building standards, the demand for energy-efficient glass has risen sharply. Curtain walls now require high-performance materials that can minimize solar heat gain (low U-value), maximize natural lighting (high visible light transmittance), control glare, and reduce harmful UV radiation. These features are crucial in enhancing indoor comfort and supporting HVAC efficiency. Tempered glass plays an essential role in meeting these sustainability goals. Frequently used in Low-E coated insulating glass units and triple-glazed systems designed for extreme climates, tempered glass combines durability with advanced thermal performance. In cutting-edge applications like Building-Integrated Photovoltaics (BIPV), it not only functions as exterior cladding but also contributes to on-site renewable energy generation, making it a cornerstone of eco-friendly curtain wall systems.
In this context, choosing a tempered glass supplier capable of integrating coatings, spacers, and performance layers is essential. HANGZHOU REACHBUILDING CO., LTD. excels in meeting such demands, offering a full line of energy-saving tempered and laminated glass products tailored for sustainable projects.
To understand the practical application of tempered glass in curtain walls, let’s explore some landmark projects where it played a vital role.
This project featured a full-height unitized curtain wall system covering the entire facade. The glass specification included 12mm tempered + 12A + 12mm low-E tempered insulated glass, supplied by HANGZHOU REACHBUILDING CO., LTD., a leading tempered glass factory. The design achieved a 70% daylighting rate and a 40% reduction in cooling load, showcasing the energy efficiency and visual clarity of premium glass products from top-tier tempered glass suppliers.
The airport's check-in hall features a striking point-supported glass wall system that enhances transparency and openness. The design utilizes heat-soaked tempered laminated glass for superior impact resistance and durability, meeting stringent international aviation safety standards. Supplied by experienced tempered glass suppliers, this curtain wall system balances architectural aesthetics with high-performance safety, demonstrating the advanced capabilities of modern glass products from top-tier tempered glass factories.
This project features a frameless curtain wall system using jumbo-size ultra-clear 15mm tempered glass panels. Supplied by a reputable tempered glass factory, the design maximizes visibility and natural ambient light while offering excellent thermal insulation. This combination enhances both aesthetics and energy efficiency in the academic environment.
These cases highlight the flexibility and performance of tempered glass across climatic zones, building functions, and architectural styles.
