The Freedonia Group is projecting nearly 4% annual growth for the $28 billion U.S. window and door market through 2023, driven by increases in building construction activity, design trends favoring more and larger (and costlier) windows and entry doors, a rising interest in smart glass, and other value-adding technologies in windows that promote building efficiencies, and intensifying severe weather patterns and other factors supporting sales of higher-value weather-resistant windows and doors.

The key determinant to window and doors sales is the health and composition of the U.S. construction industry. Although the types may vary significantly, windows and doors are necessary components of all buildings. In residential buildings, window-to-wall ratios and numbers of doors per square foot are often much higher than in commercial structures, and replacing products to keep up with design trends is far more common.

The higher strength and security needs of most commercial buildings necessitate higher-cost, higher-performing products that require less frequent replacement. Aesthetic and performance considerations–by builders, building managers, and homeowners–also inform product purchasing decisions, as evolving design trends and advances in smart glass technology are creating opportunities for higher-priced–and higher-performing–windows and doors.

Although aesthetics matter more when it comes to exterior products, interior design trends are driving a demand for more expensive niche products, such as interior barn and glass-paneled doors.

The new Freedonia Group study, Windows & Doors, analyzes key trends affecting the US market, including smart technologies, industry standards, environmental regulations and green building certification programs, as well as aesthetic and design preferences.
