A curtain wall is an outer covering of a building in which the outer walls are non-structural, utilized only to keep the weather out and the occupants in. Since the curtain wall is non-structural, it can be made of lightweight materials, such as glass, thereby potentially reducing construction costs.

Are curtain walls load-bearing?
A curtain wall is a non-load-bearing exterior wall cladding that is hung to the exterior of the building, usually spanning from floor to floor. Curtain wall vertical framing members run past the face of floor slabs, and provision for anchorage is typically made at vertical framing members only.
What is the difference between structural glazing and curtain wall?
Structural Glazing is your answer, systems that W&W Glass specialize in! Structural glazing systems, in their simplest form, are types of curtain wall systems consisting of glass that is bonded or anchored back to a structure without the use of continuously gasketed aluminum pressure plates or caps.
What type of wall is a curtain wall?
A curtain wall is a thin, aluminum-framed wall. It can come with different fillings which include glass, metal panels, or thin stones. The framing is joined to the building structure. It doesn’t bear the load of the roof or the floor; instead, it relies on the building structure, specifically at the floor line.
How are curtain walls supported?
Support of Curtain Walls
In stick-framed aluminum curtain wall, vertical mullions commonly run past two floors, with a combined gravity/lateral anchor at one floor and a lateral anchor only at the other.
Are window walls structural?
A window wall is achieved by placing glazing between a building’s concrete slabs, using the slabs as structural support. Window walls have a break between the glass, with slab covers used to conceal the concrete.
What is the difference between a curtain wall and a window wall?
Simply put, the main difference between the systems is that the window wall structurally sits between the suspended reinforced concrete slabs while the curtain wall is hung off the slab edges by anchors.A comparison is also made for the two systems’ constructability, cost, and maintainability.
How many types of curtain walls are there?
Curtain wall systems are factory pre casted systems. They are bought to the site and assembled. These are of two types based on the way each component is assembled.
What is the difference between a storefront and curtain wall?
Storefront is typically center glazed and is not self-draining. Curtain wall: In the most basic sense of the term, the curtain wall is any non-load-bearing exterior wall that hangs (like a curtain) from the floor slabs.Curtain wall typically spans multiple floors and is usually front glazed.
What is the difference between rainscreen cladding and curtain walling?
Some water may penetrate into the cavity but the rainscreen is intended to provide protection from direct rain’. So, the key distinction is that curtain walling is usually the whole envelope, while rainscreen cladding is the outer protective layer of the envelope.
How is a curtain wall attached to building?
Generally speaking, curtain wall attaches to the outside of the floor slabs, acting as a curtain that is literally hung on the building and therefore, non-load bearing. It spans slab to slab, and systems are most often constructed in one of two ways; stick-built or panelized.
What is the disadvantages of a curtain wall?
The main disadvantage of curtain walls is that their construction and maintenance costs more than another wall system. During the construction phase, they require more glass and aluminum to construct than a window-wall system, which is achieved by simply placing glazing between each floor slab in a building.
Why are curtain walls glazing?
Interior and exterior glass curtain walls:
Interior glazed systems allow for glass or opaque panel installation into the curtain wall openings from the interior of the building.Exterior glazing systems work well for low rise construction projects that allow for easy access to the exterior of the building.
Are curtain walls expensive?
Compared to window walls, curtain walls are typically more labor- and cost-intensive. That’s why they’re more commonly found in luxury commercial real estate. Yet, the higher costs do include benefits like improved structural integrity. Curtain walls offer improved resistance to moisture, wind, earthquakes, and heat.
How thick is curtain wall glass?
It can be manufactured in an almost infinite combination of color, thickness, and opacity. For commercial construction, the two most common thicknesses are 1/4 inch (6 mm) monolithic and 1 inch (25 mm) insulating glass.
What is a window wall in construction?
‘Window wall’ has become a common term in the construction industry, typically referring to a large section of glazing installed between floors, or sometimes in vertical stacks, often covering large portions of the building fa?ade.
Can glass structural?
When glass is used as a structural material, the manufacturing process must be intense and precise. Glass can be strengthened through tempering, which lessens the risk of cracking. When used in structural design, glass must be strengthened more to prevent cracks and other forms of damage.
How much do curtain walls cost?
The cost of installing a glass curtain wall for the first time ranges from $25 to $75 per square foot, resulting in a cost of $200 to $600 per linear foot for an 8-foot wall. Replacing an existing wall with a glass curtain wall is more expensive, since the original wall must be removed.
What is curtain wall advantages and disadvantages?
One of the major disadvantages of curtain walls is the need for regular maintenance. In order to keep out moisture and wind, a sealant must be applied to the perimeter, and this sealant must be replaced every 10 years or so. Another major disadvantage of curtain walls is the cost and time required to install them.
What are the parts of a curtain wall?
Glass curtain walls consist of two basic components: the glass and the frame. How these two elements are manipulated, including the proportion, properties, and anchorage of each, constitutes the essential distinction among individual curtain wall systems.
Is curtain walling the same as cladding?
There are two main differences between the cladding and a curtain wall and one of them revolves around the aesthetic of the products.While a curtain wall is not part of the exterior wall and supports only itself, cladding is also a structural piece in the construction.
