A point-fixed or spider frame supported glass curtain wall is a type of architectural facade system used in modern building construction. It is designed to provide an aesthetically pleasing and functional solution for enclosing buildings with large glass panels.
In this system, the glass panels are supported by a series of individual point fixings or spider fittings, typically made of stainless steel or other high-strength materials. These fittings are attached to the building structure, such as steel or concrete, at various points along the edges of the glass panels.
The point-fixed or spider frame system offers several advantages. Firstly, it allows for larger glass panels, which creates a seamless and transparent appearance for the building facade. It also maximizes natural light penetration, creating a bright and open interior space. Additionally, this system provides flexibility in design, allowing for complex geometric shapes and custom configurations.
The point fixings or spider fittings are designed to transfer the loads from the glass panels to the building structure while accommodating thermal expansion and contraction of the glass. The fittings are engineered to be durable, weather-resistant, and able to withstand wind loads, temperature variations, and other environmental forces.
The glass panels used in this type of curtain wall system are typically made of tempered or laminated glass for safety and structural integrity. They can be single-glazed or double-glazed, depending on the desired insulation and energy efficiency requirements.
Overall, point-fixed or spider frame supported glass curtain walls have gained popularity in contemporary architecture due to their sleek and minimalist appearance, transparency, and versatility in design. They are commonly used in commercial buildings, high-rise towers, museums, and other modern structures.
