A glazed wall system is a non-structural external wall system primarily composed of glass panels supported by a structural framing system. This system allows for extensive natural light penetration and provides a visually appealing façade.
Here's a breakdown of key aspects:
- Composition: The primary element is glass, often large panels. The supporting structure can be made of materials like aluminum, steel, or timber.
- Function:
- Aesthetic Appeal: Glazed walls create modern and visually striking building designs.
- Daylighting: They maximize the use of natural light, reducing the need for artificial lighting.
- Weather Protection: Glazed walls offer protection from the elements like wind, rain, and snow.
- Types: Glazed wall systems can include curtain walls and storefronts. Structural glazing is a specific type involving bonding glass to the framing using high-strength silicone sealants.
- Structural Considerations: The framing system must be designed to withstand wind loads, seismic forces (if applicable), and the weight of the glass.
- Energy Efficiency: Modern glazed wall systems incorporate features like low-E coatings and insulated glass units (IGUs) to improve thermal performance and reduce energy consumption.
In the context of structural glazing, the system involves bonding glass to the structural framing units of a building using a high-strength, high-performance silicone sealant specifically designed and tested for structural glazing applications. This eliminates the need for traditional mechanical fasteners, resulting in a smooth, uninterrupted glass surface.
