What are Curtain Walls? – Everything you need to Know
Over the last 200 years, the key issue for facade design has been designing quality, functionality, environmental acceptability, versatility and reliability. In meeting deadlines and costs, changing requirements led to new solutions, therefore expectations and requirements. Has anybody thought of its future? What future solutions will be led by present expectations for curtain walling?
First of all, let us study the following:
Pre 19th century, architecture was characterised by solid walls and vaulting. Then with time came the development of cast iron frame construction. This concentrated the load on slender columns and beams, thinner walls and larger windows.
In the 1930s, the primary load bearing structure was separated for the first time from the outer skin or secondary structure known as “curtain wall”. From this time on modular, pre-fabricated curtain walls began to be used for some of the high rise buildings. In the 70s the Europe manufacturers of glass developed sun reflecting, eventually triple glazing and then thermally broken curtain wall framing.
CURTAIN WALLS TODAY
Truly optimised curtain walls should respond to the user’s comfort needs and aesthetics views, regarding the ensurity of comfortable room atmosphere with minimum energy consumption. This technique dynamically adjusts to our requirements. External air-ventilated double glazed facades that do not need air-conditioning systems as long as it is not too hot outside offered a new solution.
A good example for this is the greenhouse, which is a simple but large span structure which helps to control the atmospheric temperature.
Pool and spa enclosures are another perfect applications for aluminium and glass structures.
If we see the other side of it, about its aesthetics views, the vertical glazing is long lasting and attractive ornamental details and accessories can be combined to create truly custom pride. Curtain walls are available in various applications like canopies, skylight etc.
Future Trends in Curtain Walls
Future facade technology has to reduce the complexity of new design construction and operating solutions. The overriding development objectives will, therefore, increase, the degree of prefabrication, modularity and achieve further improvements in the protection and beneficial functions of curtain walls. The type of facade should harmonise all of the curtain wall’s components including the control and regulation systems and turn them into the extremely successful system module.
Requirements for facades will increase along with the expectation of risk minimization in design construction and operation. At last to conclude, curtain walls will always increase a life of the simple buildings. The best and the most appropriate example of the curtain wall is shown in PHIS-CCI, Building of Chamber, Chandigarh.
