Frameless glass curtain wall

Types of frameless glass curtain wall

A frameless glass curtain wall is an exterior wall made primarily of glass panels, without the visible metal framing that typically surrounds windows. This design allows for a sleek, modern look that maximizes natural light and provides uninterrupted views. Here are the main types:

• Structural Silicone Glazing (SSG)

  This is a type of frameless glass wall system where the glass panels are held in place by structural silicone adhesive. The silicone is not only adhesive but also acts as a spacer to create a seal between the glass panels. This system is often used in commercial buildings because it provides a very clean, modern look with minimal visible hardware. It allows for large, uninterrupted glass surfaces. The connection points are typically sealed with silicone, making them less noticeable and contributing to the sleek design. This system is often used in commercial buildings because it provides a very clean, modern look with minimal visible hardware. It allows for large, uninterrupted glass surfaces.

• Point Supported Glass Walls

  These systems utilize metal brackets or ''points'' that support the glass panels at specific locations. The points are usually made of stainless steel or other durable metals. The glass panels are then secured and stabilized by clamping them at the points. This system creates a striking visual effect, often seen in high-end retail stores or museum entrances. Because the support structure is minimal and located at specific points, this system allows the glass to dominate visually. The transparency and continuity of the glass are emphasized.

• Spider Glass Walls

  Similar to point-supported walls, spider walls use a metal framework that resembles a spider's web. The framework consists of metal ''spiders'' that connect the glass panels to the building's structural framework. Each spider usually has four arms that attach to the corners of the glass panels. This system is commonly used in atriums, canopies, and other areas where a large, open glass structure is needed. The design of the metallic framework allows for significant spans of glass. The framework distributes the weight of the glass panels to the building's structure at multiple points. This helps prevent any one point from bearing too much weight and potentially breaking.

Functions and features of frameless glass curtain wall

Frameless glass walls have various functions and features that offer different benefits.

• Structural Integrity

  The frameless glass wall elements are often made of strong, tempered, or laminated glass. This enhances structural integrity and safety. The glass panels use structural silicone to attach to each other and to the floor. This silicone provides stability and weather protection by sealing the joints. Sometimes, there are also metal brackets, but they are minimal and not as in traditional framed walls.

• Aesthetic Appeal

  Frameless glass walls look modern and clean. They have fewer visible connections or frames, giving a seamless look. This allows for uninterrupted views and maximum natural light.

• Customization

  These walls can be tailored to fit different spaces and design preferences. The glass can come in different thicknesses, textures, and tints. The size and shape of the panels can also be adjusted to fit specific needs.

• Light Control

  There are different glass types for controlling light. Some reduce glare or block UV rays. Others let most light in but offer privacy. Examples include tinted, frosted, or reflective glass.

• Insulation

  Frameless glass walls can still provide good insulation. Double or triple glazing is available. This has two or three glass layers with spaces in between. It reduces heat loss or gain. Argon or krypton gases fill the spaces and further insulate.

• Ease of Maintenance

  Frameless glass walls are simple to clean. They do not have many frames or joints where dirt gets stuck. Special coatings can also be added to the glass. These make dirt slide off when it rains and prevent stains.

• Transparency

  Transparency is the main feature of frameless glass walls. They allow people to see through clearly. This connects indoor spaces to the outdoors. Transparency makes indoor areas feel more open and bright.

• Durability

  The frameless glass wall materials are durable. They can withstand weather and everyday use without damage. While they seem delicate, the glass is usually toughened or tempered. This undergoes heating to increase its strength significantly. Toughened glass resists scratches, cracks, and breaks more than regular glass.

How to choose frameless glass curtain wall

When selecting a frameless glass curtain wall for a project, it is essential to consider several elements to ensure the final product meets the desired aesthetic and functional needs. Here are some factors to consider:

• Understand Project Needs

  Assess the requirements of the project. Consider the type of building, its location, and climate. Is it a commercial or residential building? What is its intended purpose? What is the local climate like? These factors will influence your choice of a frameless glass curtain wall system.

• Consider the Aesthetic Design

  Look at the architectural style of the building and the desired appearance of the glass wall. Clear, tinted, or frosted glass can be used to create different visual effects. The glass can also be printed or etched with patterns. Think about the view: transparent glass maximizes the view, while reflective or tinted glass can provide privacy.

• Energy Efficiency

  Opt for low-emissivity (low-e) glass, which has a thin, transparent coating that reflects heat back into the building in winter and keeps heat out in summer. Double or triple glazing provides insulation and reduces noise. Some glass walls can incorporate solar panels or other renewable energy sources.

• Safety and Security

  Ensure the selected glass meets safety standards. Laminated or tempered glass is recommended as it breaks into small, blunt pieces or stays in a spider web on the frame, reducing the risk of injury in case of an accident. Consider security needs such as alarms and surveillance cameras.

• Understand the Costs

  Frameless glass walls can be expensive, so balancing cost and quality is essential. Consider the initial cost and long-term savings on maintenance and energy. More efficient glass may have a higher upfront cost but save money over time.

• Maintenance Requirements

  Choose glass that is easy to clean and maintain. Consider self-cleaning glass or coatings that repel dirt and water. Frameless glass walls may require more maintenance than framed walls to keep them clear and free of streaks.
