Window Walls

Typically factory-glazed window and door units installed between the floor slabs of multiple-story buildings. When the floor slabs edges are covered on the exterior with aluminum slab covers, the resulting appearance is that of curtain wall. Window walls are often referred to as store front systems and are non-structural. As the window wall is non-structural it can be made of a lightweight material reducing construction costs. When glass is used as the curtain wall, a great advantage is that natural light can penetrate deeper within the building. The window carries only its own dead load weight. 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 window wall is designed to resist air and water infiltration, sway induced by wind and seismic forces acting on the building.

Window wall Systems are typically designed with extruded aluminum members, although the first walls were made of steel. The aluminum frame is typically infilled with glass, which provides an architecturally pleasing building, as well as benefits such as day lighting. Other common infills include: stone veneer, metal panels, louvers, and operable windows or vents are often used in conjunction with glass compliment the overall system design.

Curtain walls differ from Window wall 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. Window wall or store front systems are available unitized or sick built. We often design the system as unitized for utmost efficiency during the construction process.
