Like any building exterior, commercial buildings also need structural integrity and weather protection in practical applications. One distinctive feature of the modern curtain wall design is its non-structural nature. As a result, any wind-loads and stresses transfer to the main building structure. Thermally efficient, fully sealed, built-in expansion and easy installation are other benefits. Besides, the impressive size capability, as well as flexible configuration, also gives greater scope to architects. Colours, glass choices, and aesthetics all create better architecture for commercial buildings today.
Types of Aluminium Curtain Wall Used in Commercial Buildings
1) Pressure equalised systems uses gaskets, pressure plates and external cappings. This type of aluminium curtain wall generally keeps the interior of the building fully sealed with any water effectively draining down the mullions or through the cappings to the outside.
2) Face sealed system like glass-to-glass relies on absolute precision sealing. In most cases, curtain walling relies on aluminium mullions and transoms forming the main grid. The vertical or horizontal bars in curtain walling come in various sizes and depths. Profile sizes start at around 50mm depth, up to substantial mullions at up to 200mm deep or more. Additional reinforcing is also added where required. The result is a super-strong structure with excellent resistance to deflection.
Aluminium curtain wall will be available in either modular or stick form, depending on the specific requirements in applications. In some cases, mullions and transoms are available in a variety of depths to suit the site condition or load and external cappings are again available in profiled or standard forms to accommodate special designs if needed. In front of the main mullion are gaskets, glass, more seals, the thermal pressure plate and finally the exterior capping. While aluminium has been widely used in curtain wall frames, it’s also possible in PVCu, timber, steel and a combination of materials. Timber is also a strong solid material, but PVCu often comes reinforced with steel or aluminium internally. For low-rise applications, like school refurbishments and residential projects, PVCu does work well within the limitations of the system. However, PVCu still cannot achieve the look of the aluminium variety nor can it achieve the spans.
