Curtain walls, also known as cladding or building façade, are one type of building skin separating interior from exterior environments. Unlike masonry or precast facades, curtain walls are non-load-bearing. Methods of producing and installing curtain walls are defined and explained.
In UAE, there are two types of systems, that is
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. The glass can be comprised of monolithic, laminated, dual-glazed or even triple-glazed insulating glass units (IGUs). The back-up structure may use horizontal and/or vertical aluminum mullions or be a glass mullion, steel blade, cable or stainless steel rod. The interior and exterior may use extruded silicone/EPDM gaskets, or a wet sealed silicone depending on the system. This system creates a completely clean, flush exterior appearance while the interior members have many different options depending on design and budget.
Aluminium composite panel (ACP), also aluminium composite material (ACM), is a type of flat panel that consists of two thin aluminium sheets bonded to a non-aluminium core. ACPs are frequently used for external cladding or facades of buildings, insulation, and signage. If the core material is flammable, usage may be problematic as a building material and some jurisdictions have banned their use.Aluminium sheets can be coated with polyvinylidene fluoride (PVDF), fluoropolymer resins (FEVE), or polyester paint. Aluminium can be painted in any kind of colour, and ACPs are produced in a wide range of metallic and non-metallic colours as well as patterns that imitate other materials, such as wood or marble. The core is commonly low-density polyethylene, or a mix of low-density polyethylene and mineral material to exhibit fire retardant properties.
