The curtain wall system has evolved rapidly over the last two decades, especially with respect to weather control performance. A curtain wall system is a lightweight exterior cladding which is hung on the building structure, usually from floor to floor. It can provide a variety of exterior appearances but is characterized by narrowly spaced vertical and horizontal caps with glass or metal infill panels. These system provide a finished exterior appearances and most often a semi-finished interior as well. They are also designed to accommodation structural deflections, controls wind-driven rain and air leakages, minimize the effects of solar radiation and provide fir maintenance free long term performance. Most of today;s metal curtain wall systems are constructed of lightweight aluminium.

Aluminium composite material is made of low Density Polyethylene. The Polyethylene core in laminated between two high-strength coil coated aluminium sheets. Polyvinylidene Fluoride (PVDF) is a high performance fluoropolymer architectural coil coating system from PPG Industries. ACP sheets can br easily fabricated (i.e. cut, bent, curved, drilled, grooved, punched and shaped) using common wood and metal working tools to suit specific design requirements.

Structural glazing systems incorporating spacers and adhesives are now a widely accepted glazing option and are used in a growing share of curtain wall, window and storefront installations. In fact, many people have come to regard structural glazing as the superior method of glazing. When properly installed, the structural sealant forms a continuous, waterproof seal against leakage and air infiltration. The sealant and spacer transmit wind load movement to the structre and withstand flexure, tension, compression and differential thermal shear stresses. Silicone resists UV, ozone and other environment exposures and dose not take on a compression set or lose resiliency. The major issue that govern the design of structural glazing system are sealant performance air and water infiltration structural design requirements, and the use of right type of glass. These requirement directly affect aluminium profile sized, sealant widths and join sizes.
