Curtain walls and window walls are two glazing methods often used by business owners, designers, and builders. Both of these designs use large panels of glass a significant component of the exterior of the building. Both curtain walls and window walls add ample natural light and visibility in retail stores, restaurants, office complexes, and apartment buildings.
But what is the difference between a curtain wall and a window wall?
Curtain Wall Window Construction
Curtain walls are most commonly used in commercial construction. A curtain wall is a non-bearing wall of glass hung from the edges of the concrete floors in a building. Curtain wall glazing creates a solid wall of glass on the exterior of a building, and it is an elegant and modern-looking style often used on high-rise buildings.
Curtain walls are more costly than window walls because they are site-assembled and involve more custom glass manufacture, engineering, and labor costs to install. However, they are also stronger than window walls when it comes to resistance to earthquake forces, wind, and extreme weather.
Window Walls for Commercial and Residential Construction
For many commercial and residential builders and designers, commercial window wall systems are the most cost-effective solution for adding maximum glazing to a building.
Window wall systems are easier to install than curtain walls and can be set in place from the interior of the building — this ease of installation results in part of the cost-savings with this type of window system.
Window walls are commonly used in both commercial and residential construction. This glazing method gives a maximum of view and natural light when placed next to decks, patios, balconies, or when used as an entryway in a retail business.
