A curtain wall is a glazed wall system hung off a concrete slab using anchors. Curtain walls are self-supporting and give a building’s exterior the look of top to bottom glass. Most often used on commercial buildings, curtain walls are typically installed from the outside of a building using cranes or rigs.

A window wall is achieved by placing glazing between a building’s concrete slabs, using the slabs as structural support. Window walls have a break between the glass, with slab covers used to conceal the concrete. Window walls are often used in residential applications as they allow for more customizable sections such as windows and balcony doors. They are most commonly installed from the inside of a building, which is safer, more efficient and more cost-effective.
