This study examines the US window and door market by product, material, market, and geographic region in value terms at the manufacturers’ level (i.e., excluding the value of features and services added between the manufacturer and end user). Historical data for 2008, 2013, and 2018 and forecasts for 2023 and 2028 are presented in US dollars. The value of installed glazing is included in the demand numbers for all window and door products. The study also presents unit demand for prime windows and selected door product types – entry, patio, and interior doors.

Demand in unit terms for windows and exterior doors is determined by the number of openings that are filled. Interior door units are counted by the slab (e.g., a bifold interior door would count as two interior door units).

Also for the purposes of this study, windows and doors classified as “energy efficient” are those products that meet current ENERGY STAR criteria, while those classified as “impact resistant” are those that meet local and regional building code requirements for being able to withstand high winds or impacts.

To avoid double counting, parts and components sold to, or imported by, door manufacturers for assembly into new windows and doors are excluded from the scope of this study. The value of these products is included here when they are sold as part of an integrated new window or door unit.

Also excluded from the study scope are:

• replacement window and door components and accessories, including separately sold frames, sashes, screens, hinges, locks, latches, and weatherstrip
• separately sold hardware not typically sold as part of the window or door unit (e.g., door knobs, locks, door stops, garage door openers)

In addition, this study excludes windows and doors for automobiles and other transportation equipment, and cabinets; fencing gates; shower doors and bathroom stall doors; elevator doors; pet doors; and moulding and trim.

Window and door demand is segmented into the following product types:

• prime windows (double- and single-hung, casement, horizontal sliding, horizontal swing)
• specialty windows (curtain wall with an infill of glass, storefront, stationary, skylight, storm, roof, tilt-turn, and glassblock)
• interior doors (wood panel, wood flush, molded wood, bifold, louver, pocket, screen, pantry, manifold)
• exterior doors (entry, patio, residential garage, commercial overhead, storm, screen, revolving, and security)

Demand for windows and doors is also analyzed in terms of material type:

• wood (including wood lumber, engineered wood, and cladded wood)
• metal (including steel, aluminum, and other metals, such as iron and bronze)
• vinyl (including standard PVC and wood-plastic composite)
• fiberglass

The vinyl materials category also includes high-density polyethylene, polyester, and nitrile rubber doors, demand for which is modest.

Demand is also provided in terms of market:

• residential (new and replacement single-family, multifamily, and manufactured housing)
• commercial (new and replacement office, retail, and lodging; institutional; industrial; and transportation and other commercial structures)

The study also presents price deflators for selected major product types, with prices in 2012 equaling 100.

Window and door demand is broken out for the following US geographic regions and subregions:

• Northeast (Middle Atlantic and New England)
• Midwest (East North Central and West North Central)
• South (South Atlantic, East South Central, and West South Central)
• West (Mountain and Pacific)
