This study examines the global 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, including door hanging and finishing operations not offered by the door slab manufacturer). Historical data for 2010, 2015, and 2020, and forecasts for 2025 and 2030 are provided in US nominal dollars.

For the purposes of this study, the value of installed glazing is included in the demand numbers for all window products. Windows with multiple openings (e.g., bay and bow types) that are sold as one unit are considered to be one window.

For doors, the value of installed glazing, sidelites, and/or transoms is included if these features are sold by the manufacturer as part of the framed system.

Major window products included in the study are:

• single- and double-hung windows
• casement windows
• sliding and swing windows
• architectural and stationary windows

Major door products include the following types:

• interior – including panel (e.g., stile-and-rail, and French), flush, and molded
• entry (manually opened)
• sliding patio (including multi-slide types)
• swinging patio (including multifold types)
• residential garage
• automated sliding and swinging
• overhead (including sectional and rolling steel and high-speed plastic roll-up types)
• storm

The study also includes a number of smaller window and door product segments.

To avoid double counting, parts and components sold to, or imported by, manufacturers for assembly into new windows and doors are excluded from the scope of this study.

Also excluded are:

• windows and doors for automobiles or other transportation equipment
• windowed cabinets
• fencing gates
• shower doors and bathroom stall doors
• elevator doors
• pet doors
• moulding and trim

Separately sold replacement hardware not typically sold as part of the window or door unit (e.g., door knobs, locks, door stops, and garage door openers) are outside the scope of this study. However, the value of these products is included when they are sold as part of an integrated new window or door unit.

Window and door demand is segmented by the following framing materials:

• metal
• wood (including natural and engineered wood)
• vinyl (which includes wood-plastic composites)
• fiberglass

Engineered wood products include those manufactured from particleboard, plywood, medium density fiberboard (MDF), and laminated veneer lumber (LVL).

The wood segment includes wood doors clad with metal or plastic materials but that have a wood interior. Wood windows include only those products in which all the framing components (e.g., jambs, sills, stiles, rails, and mullions) are made of wood.

Window and door demand is also segmented into the following markets:

• new residential buildings
• residential building improvement and repair
• new nonresidential buildings
• nonresidential building improvement and repair

The new residential and nonresidential markets include only those products installed in the construction of new residential and nonresidential structures. Improvement and repair markets encompass windows, doors, and related components sold to replace or repair existing products, or as part of a remodeling, renovation, or expansion project.

Excluded from the definition of residential buildings are housing units located in a structure whose primary purpose is something other than habitation. Thus, a small living space contained in a larger retail facility would be classified as part of a retail building and not a residential building.
