Glass Curtain Wall Panels Producing and Installing Companies
Nowadays there are many glass curtain wall panels producing and installing companies that are producing different types of this product and supply their products at affordable prices in real market and some online stores. With the advent of glass making machines, the use of glass in modern facades of buildings has been increasing. The glass facade of the building can be widely used to protect and insulate buildings against noise, climate and environmental pollution. This type of facade is usually created more than 40 cm away from the main facade of the building.
How does a curtain wall system work?
As a whole a curtain wall system 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, thereby reducing construction costs. When glass is used as the curtain wall, an advantage is that natural light can penetrate deeper within the building.
The curtain wall facade does not carry any structural load from the building other than its own dead load weight. The wall transfers lateral wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, absorb sway induced by wind and seismic forces acting on the building, withstand wind loads, and support its own dead load weight forces.
Curtain wall systems are typically designed with extruded aluminum framing members, although the first curtain walls were made with steel frames. The aluminum frame is typically infilled with glass, which provides an architecturally pleasing building, as well as benefits such as day-lighting. However, the effects of light on visual comfort as well as solar heat gain in a building are more difficult to control when using large amounts of glass infill. Other common infills include: stone veneer, metal panels, louvres, and operable windows or vents.
Curtain walls differ from storefront systems in that they are designed to span multiple floors, taking into consideration design requirements such as: thermal expansion and contraction; building sway and movement; water diversion; and thermal efficiency for cost-effective heating, cooling, and lighting in the building.
How many types of curtain walls are there?
Nowadays Curtain walls are precast at a factory and assembled before they are brought to the site. Basically, there are two types of curtain wall systems depending on the method by which the components are assembled.
- Stick Curtain Wall System: In this type of curtain wall system, the components are assembled piece by piece on the structure of the building. This system is mainly used for low-rise buildings or in small regions. This is due to the fact that for reaching higher elevations it is important to have exterior access. This system promises flexibility as it gives space for onsite adjustments. Though it has the advantage of low shipping costs, the labor and time consumption should not be underestimated as tend to run quite high.
- Unitized Curtain Wall System: In this type of curtain wall system, the parts are already assembled in the factory. The components are installed and brought as a single unit from the factory to the site. This negates the need for individual installation. The size of the unitized curtain walls is directly proportional to the floor to floor height of the structure. Popular in high-rise buildings, they don’t need external supports such as cranes or scaffolding. Only mini cranes or temporary hoist are needed. This system offers the benefits of quick construction and good quality as the components are manufactured in a factory setting. However, this type of curtain wall system tends to increase the shipping charges due to need for larger and better protection during transportation to the site.
Differences between a window wall and a curtain wall?
Nowadays there are two main types of glass cladding systems: the window wall and the curtain wall. They are quite similar and the terminology can even be confusing. The window wall has been considered by some as a type of curtain wall and perhaps even more blurring is that when the curtain wall technology was first being developed, it was referred to as a window wall.
There is very little written in academia about the window wall, perhaps because it is lumped into articles that discuss curtain walls. In the Canadian construction industry, there is a clear difference between the systems. Simply put, the difference between the systems is that the window wall structurally sits between the slabs and the curtain wall is hung off the slabs. However, there are many more intricacies that make these systems different.
First of all, the curtain wall is aesthetically slick, modern and desirable for many architects. It is used primarily for commercial buildings, and some unique residential projects. Curtain walls are structurally engineered and typically installed from the outside using a crane or a rig, which make them more expensive than their competitor and more rigorous to install.
The window wall is generally less expensive and is installed from the building interior, but in early versions provided a break at every floor which detracted from its sleek continuity. They are almost exclusively used in residential buildings since they provide a practical and cost effective method to install highly glazed cladding, while still allowing balconies and operable windows. With modern window wall systems, it is possible to closely mimic the sleek aesthetic look of a curtain wall.
Commercial Curtain Walls at Affordable Prices
Nowadays there are many manufacturers that produce different types of commercial curtain walls that supply their products at affordable prices in real market and also some online stores. for example a huge numbers of curtain wall products are offered for sale by suppliers on some reputable online stores.
