Glass curtain wall is a modern building exterior structure, composed of metal frame (such as aluminum alloy) and glass panel, which has beautiful, lighting and energy-saving functions. The following are its core features and classifications:
I. Main features
- Transparency: large area of ??glass provides natural lighting and creates an open vision.
- Lightweight: Compared with traditional walls, it is light and reduces the building load.
- Flexible design: customizable shape, color and glass type (such as coating, hollow glass).
- Energy saving and environmental protection: Low-E glass or double-layer hollow design is used to reduce energy consumption.
- Fast construction: prefabricated components are assembled on site to shorten the construction period.
II. Common types - Frame curtain wall
- Exposed frame: metal frame is exposed and the structure is stable;
- Hidden frame: frame is hidden, full glass visual effect.
- Point-supported curtain wall
Glass is fixed by metal joints and is often used in large-span spaces (such as airports and theaters). - Full-glass curtain wall
Frameless design, glass ribs or adhesive support, suitable for shopping malls and hotel lobbies. - Unitized curtain wall
Factory prefabricated integral units, on-site hoisting, high precision and short construction period. - Smart curtain wall
Integrated high-tech such as dimming glass and photovoltaic power generation, dynamically adjust light temperature.
III. Core functions - Wind and rain protection: Sealed design ensures the airtightness of the building.
- Heat and sound insulation: Hollow/vacuum glass reduces heat conduction and noise.
- Safety protection: Tempered glass and laminated glass are impact-resistant and shatter-resistant.
