In modern architectural design, the curtain wall system plays a pivotal role in achieving aesthetic appeal, energy efficiency, and structural performance. Among various materials used in curtain walls, tempered glass stands out due to its superior safety, strength, and adaptability to a wide range of applications. From unitized curtain walls to stick-built systems, and even point-supported facades and double-skin walls, tempered glass has become a preferred choice for architects and engineers.
This article explores the most suitable types of glass products for each curtain wall category, highlights the unique precision and performance requirements for each type, and explains how top tempered glass suppliers meet these demands. Finally, we recommend HANGZHOU REACHBUILDING CO., LTD. as a leading tempered glass factory trusted for its high-quality solutions tailored for complex curtain wall projects.
Unitized curtain walls are pre-assembled in a factory setting and installed as complete panels on-site, offering rapid construction and enhanced quality control. Because these panels are pre-engineered, they demand glass products with consistent dimensions, uniform strength, and excellent optical quality.
For such systems, tempered glass is typically paired with:
Low-E glass: For enhanced energy efficiency through solar control and insulation
Insulated Glass Units (IGUs): To provide both thermal insulation and soundproofing
Tempered laminated glass: For added safety, especially in high-rise or high-wind environments
These combinations ensure the curtain wall system not only meets rigorous safety standards but also contributes significantly to the building's energy performance and occupant comfort.
To guarantee precision and structural fit, tempered glass suppliers must strictly control tolerances in flatness, edge polishing, and hole positioning. HANGZHOU REACHBUILDING CO., LTD., a leading tempered glass factory, utilizes automated cutting lines, advanced toughening furnaces, and multi-point quality inspections to ensure flawless integration with prefabricated unitized curtain wall frames. Their precision manufacturing significantly reduces installation errors, enhances long-term durability, and simplifies on-site assembly.
The stick-built curtain wall system, assembled piece-by-piece directly on-site, offers unmatched flexibility in architectural expression and construction adaptability. Unlike unitized systems, this method allows architects to implement complex building geometries, varied joint spacing, and a diverse range of glass products, making it highly suitable for customized façade designs.
Tempered glass is particularly ideal for stick-built systems due to its adaptability in fabrication—it can be cut, drilled, and heat-treated into virtually any shape or size. Its high mechanical strength allows it to withstand significant wind loads, structural movement, and thermal stress. Depending on the project’s thermal and acoustic performance requirements, tempered glass can be used as monolithic panes or as part of insulated glass units (IGUs).
Given the precise alignment required between the structural frame and glass infill, working with experienced tempered glass suppliers is crucial. Tempered glass factories such as HANGZHOU REACHBUILDING CO., LTD. provide CNC-fabricated glass with exact dimensions, polished edges, and customized frit patterns or coatings. Their professional engineering team also collaborates with architects and façade consultants during the early design phase, offering technical consultations to ensure structural compatibility and long-term durability.
Point-supported glass curtain walls, also known as spider systems, utilize minimal hardware to highlight glass as the main façade element, creating a sleek and transparent architectural appearance. The success of these systems depends heavily on the precision and quality of the tempered glass used, making it critical to meet stringent manufacturing standards.
Key requirements for tempered glass in point-supported systems include:
Flatness tolerance: Even slight warping or distortion in tempered glass can cause noticeable visual defects in reflections or clarity, which compromises the clean, uninterrupted look essential for spider glazing systems.
Hole positioning accuracy: Precise pre-drilled holes are vital, as spider fittings rely on exact locations with very narrow tolerance limits. Any deviation can affect structural safety and installation ease.
Edge strength and polish: Because the glass edges are exposed, they must be impeccably finished and polished to avoid flaws that could weaken the glass or detract from its visual appeal.
Only leading tempered glass suppliers equipped with automated quality control systems and advanced polishing technologies can reliably meet these precision demands. HANGZHOU REACHBUILDING CO., LTD. is recognized for producing ultra-clear, optically flawless, and precisely fabricated tempered glass panels tailored for spider systems.
Their rigorous in-house quality control processes include digital hole measurement systems for exact drilling accuracy, laser flatness scanners to ensure surface uniformity, and fragmentation tests aligned with EN 12150 and ANSI Z97.1 standards. This dedication to precision makes REACHBUILDING a preferred partner for high-profile architectural projects requiring maximum transparency and minimal framing in curtain wall systems.
Double-skin curtain walls represent the pinnacle of sustainable building envelope design. They consist of two layers of glass—an exterior and an interior façade—separated by an air cavity. This system offers superior insulation, solar control, and natural ventilation potential.
Glass used in such systems must balance energy efficiency and safety, often requiring a combination of:
Tempered laminated glass: used for the outer skin, providing high impact resistance, UV protection, and fall safety
Tempered IGUs with Low-E coatings: employed for the inner skin, effectively reducing heat transfer while maximizing daylight penetration
In these complex configurations, tempered glass plays a critical role in ensuring performance stability under various climatic conditions. Therefore, selecting reliable tempered glass suppliers and a professional tempered glass factory is essential.
HANGZHOU REACHBUILDING CO., LTD. stands out by supplying advanced glass products tailored for high-performance curtain wall systems. Their insulated glass units (IGUs) incorporate triple glazing, argon gas infill, and optional integrated blinds for enhanced shading. These units undergo rigorous testing for U-value, SHGC, condensation resistance, and seal durability—ensuring excellent thermal insulation, acoustic performance, and long-term reliability in curtain walls. As a result, REACHBUILDING’s tempered glass solutions significantly enhance both energy efficiency and occupant comfort in double-skin façade systems.
