More about Curtain Walling

A curtain wall system is an outer covering of a building in which the outer walls are non-structural, and therefore can be manufactured of a lightweight material, such as aluminium, reducing construction costs. When glass is used as the curtain wall the great advantage is that natural light can penetrate deeper within the building. The curtain wall facade only carries its own weight and no dead load weight from the building. The wall transfers horizontal wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, sway induced by wind and seismic forces acting on the building and its own dead load weight forces.

Curtain wall systems are typically designed with extruded aluminium members. The aluminium frame is typically infilled with glass, which allows in large amounts of natural light creating a feeling of space and providing the perfect interface with the outside world whilst maintaining the safety, security and comfort levels of the buildings internal environment for the benefit of its occupants. Other common infills include stone veneer, metal or insulated panels, louvers and operable windows or vents. Curtain walls differ from store front systems in that they are designed to span multiple floors, and take into consideration design requirements such as: thermal expansion and contraction; building sway and movement; water diversion; and thermal efficiency for cost effective heating, cooling and lighting in the building.
