Glass curtain wall

Types of glass curtain wall

A glass curtain wall is a thin, exterior wall. This wall consists of glass panels and metal frames. It is non-structural and does not support the weight of a building. The weight of a glass curtain wall is instead held by the building's structural frame. The glass wall is commonly used in modern buildings. These walls create a light, airy feel by allowing natural light to flood into the interior spaces while providing a clear view of the outside.

Glass curtain walls come in different types, as outlined below:

• Stick-built curtain wall

  The stick-built glass curtain wall is a system of non-load bearing walls. These walls are made up of vertical and horizontal metal framing. This framing is filled in with glass panels. The metal framing acts like a skeleton, supporting the glass panels. It is usually made of materials such as aluminum. Aluminum is preferred because it is lightweight and resistant to rust.

  The name "stick-built" comes from the way the walls are constructed. Similar to building a wooden stick frame house, the walls are assembled on site using individual "sticks" or pieces of metal framing. This system allows for more flexibility in design.

• Unitized curtain wall

  A unitized glass curtain wall is a more modern approach to building exterior walls. Instead of putting the metal framing and glass panels together one piece at a time on site, the unitized system is made off-site in a factory. Each wall section, with its metal framing and glass, is fully assembled like a big puzzle piece.

  Once a section is complete, it is already ready to be attached to the building. This method speeds up the building process because the walls go together quickly on-site since they are already assembled.

• Structural glazed curtain wall

  A structural glazed glass curtain wall is similar to a stick-built wall but with one key difference. Instead of having glass panels fit into metal frames, this wall uses special adhesive to attach the glass directly to the metal framing. This makes for a very sleek and clean look because the glass appears smoother without the metal frame breaks.

Function and Feature of Glass Curtain Wall

• Building Envelope:

  A glass curtain wall acts as a building envelope. This is a non-structural exterior wall. It protects the interior from weather elements. These include; winds, rain, and snow. Snow and rain are not able to penetrate the interior. This is because glass walls have seals. They also have frames that resist water.

• Aesthetic Appeal:

  Glass wall systems make buildings look beautiful. They have sleek and modern designs. They also allow natural light to brighten the inside. Transparent walls create a connection between the inside and outside. This is especially true for skyscrapers in urban areas.

• Structural Integrity:

  Glass walls are stable. They are made with materials like aluminum and strong glass. These materials make sure the wall can resist wind pressure. They also enable the wall to remain stable when there is an earthquake.

• Energy Efficiency:

  Some glass curtain walls have special glass. This glass helps to manage heat from the sun. It keeps buildings cool during summer. It also reduces the need for air conditioning. This glass also prevents heat from escaping during winter. Curtain walls with this glass enable buildings to save energy.

• Customization:

  Glass walls can be adjusted to fit different building needs. They come with different types of glass, frame materials, and colors. This allows architects and builders to create glass walls that match their building designs. For example, some glass walls can be made to open up like doors or windows.

• Durability and Low Maintenance:

  Glass curtain walls are long-lasting. They can resist scratches and dirt. They only need to be cleaned regularly to maintain their transparency and beauty.

• Versatility:

  These glass walls can be used for different types of buildings. For example, they can be used for offices, hotels, hospitals, and shopping centers. They also fit different styles, from modern to traditional.

Scenarios of glass curtain wall

Glass curtain walls are non-structural exterior walls made of glass that are frequently used in modern building design. They offer a variety of use cases, including:

• Commercial Office Buildings

  Glass curtain walls are frequently used in corporate office buildings to give a contemporary, polished appearance. They improve the working environment by letting in natural light and providing stunning views of the surroundings.

• Hotels and Resorts

  Hotels and resorts use glass curtain walls to create a welcoming first impression. These glass walls give visitors breathtaking views and a sense of luxury.

• Museums and Cultural Institutions

  The glass curtain wall design allows museums to display their collections to the public while maintaining the works of art. Additionally, it gives cultural institutions a modern, elegant appearance.

• Retail Stores

  Retail businesses use glass curtain walls to draw clients in and show off their wares. Shoppers are drawn inside by the transparent facade, which enables them to see products on display.

• Residential Buildings

  Glass curtain walls are used in high-end residential buildings to give them a sleek, contemporary appearance. They also provide residents with stunning views and plenty of natural light.

• Universities and Educational Institutions

  Libraries, lecture halls, and student centers are just a few examples of the buildings on campuses of universities that use glass curtain walls. These walls create a stimulating learning environment by letting in natural light.

• Healthcare Facilities

  Hospitals and clinics utilize glass curtain walls to create welcoming spaces for patients and staff. Natural light is important in healthcare settings because it helps people feel better.

• Parking Garages

  For parking garages, glass curtain walls provide a contemporary appearance and let in light. They make these structures more aesthetically pleasing and show that they are an important part of the building.

• Airports and Transportation Hubs

  Glass curtain walls are used at airports to make check-in counters, security screening areas, and baggage claim zones transparent and visible. This makes it easier for travelers to find their way around. Additionally, these walls give transportation hubs a sleek, contemporary appearance.

• Industrial Facilities

  Although they are not as common as for other building types, glass curtain walls can still be used for some industrial buildings, such as showrooms and corporate headquarters. They give industrial sites a modern look and let in natural light.

How to Choose glass curtain wall

• Location

  The first thing to consider is where the building will be. If it's in a place with really strong winds, a lot of rain, or extreme temperatures, a structural silicone glass wall that is bolted to the frame might work best. It will stay securely attached even in bad weather.

• Budget

  Curtain walls attached with silicone are usually cheaper. If the budget is tight, this could be the better choice. But if the location has difficult weather, the silicone walls may not hold up as well long-term compared to the frame-attached walls.

• Aesthetic Considerations

  Both types of wall give a sleek, modern look. Silicone walls may have fewer metal parts showing, so they could look more stylish. But the frame-attached walls let designers play more with shapes and styles.

• Building Use

  If the building will have heavy things inside, like lots of people or machines making noise, the frame-attached wall will be stronger. It can handle more pushing and pulling forces. Silicone walls are good for empty spaces or buildings just for shows.

• Glass Type

  The glass used also matters. Thicker glass makes for a sturdier wall, whether attached with silicone or frames. But thinner glass cuts weight and cost. Silicone walls work better with lightweight glass. Frame walls need thicker glass for strength.

• Installation Skills

  Putting up silicone walls takes special skill that costs more. If the builders are not as experienced, the frame-attached walls may be safer. They are easier to install and fix if something goes wrong.
