Aluminum cladding is cladding that is created using a thin coating of aluminum on the exterior of the product. Cladding in general is the application of one type of substance or material over a different material, effectively creating a protective layer on the underlying material. The use of aluminum, sometimes spelled “aluminum,” in creating high-quality cladding is common, especially with architecture products like windows and doors.
In some instances, aluminum cladding is manufactured using a process known as extrusion. This is usually the case when the aluminum is serving as a skin over another metal. Essentially, the process calls for compressing the two metals together using some type of high-pressure equipment, or using some sort of die to create the adhesion. In both processes, extreme and constant temperatures of heat are necessary to create the necessary bond.
A number of building materials are clad with aluminum. For example, wood window cases are sometimes outfitted with aluminum cladding as a means of adding strength to the casings and the window sashes. The exterior skin helps to protect the wood from weather damage, extending the life of the casings for a number of years. As an added benefit, the presence of the cladding makes it much easier to clean the casing using basic cleaning products.
