Maybe for some of those involved in construction, including employers, engineers and contractors, speaking of modern views, still associated with the use of glass facades of high-rise buildings or in combination with other materials such as stone and wood. After research and study of engineering reference texts and resources, such as chapter V of the National Building Regulations (2nd revision),you can see only materials such as stone, wood and glass are raised as materials used in building facades and the pattern of use of these resources are checked. However, that aside from the issue will be raised in the paper, in recent years, building facades industry has completely changed in the country which subsequently changed the face of big cities, small and even non industrial.
Despite the expansion in the distribution of various products and applications in the building façade, yet as it should be, scientific-technical and mechanical of these materials has not been examined. It also cannot claim that there is an indispensable reference for construction heads, to know the quality and quantity of their installation standard principles So far.Of course some text on new materials are published in many developed countries and their mechanical properties and installation methods are explained.
Aluminum position among other composite materials
Since this product is of industrial materials and manufacturing products, many properties of natural materials such as stone and wood has been improved. So that the product shows extraordinary resistance against weather conditions and UV radiation, strong acidic and alkaline conditions, contamination and corrosion and discoloration (If using PVDF resin) . And maintain physical and technical properties without change for many years. In terms of mechanical, elasticity and excellent flexibility of sheets , unlike the special materials, can be distorted in any arbitrary form. The product is produced in many different colors and designs. So that in addition to colors in nature it can produce in the form of stone, wood and even different shades of color depending on the angle of light and everything that can be imagined. As mentioned, composite sheet has the weight of 6.5 kilograms per square meter that in comparison with other materials such as stone, glass and cement has the lowest possible weight.
The survey was conducted, aluminum facades is 90% lighter than granite, 65 percent lighter than cement and 50 percent lighter than glass, that the weight loss will be checked in the usage benefits of the of this product. This product is part of sealing materials and also has acoustic properties. Also, if for any reason you need to replace them,this is easily done, while other materials generally have a lot of weaknesses in all of the above.
The product segmentation in terms of usage
Unlike the existing building, in terms of time optimizing and the economic projects plan, Composite sheets depending on the efficiency of the project as well as the sensitivity level of usage and installation, offer a wide range of options to consumers.
Differences are affecting the price and quality of these products occurs mainly in the following cases:
The difference in the aluminum alloy
The difference in the type of polyethylene, or the middle layer
The difference in the thickness of the aluminum layer and the middle layer
Design or special colors
