A. INTRODUCTION AND METHODOLOGY 

Ducker Worldwide has been conducting the study of the U.S. residential and 

nonresidential window and door markets for the WDMA (Window & Door Manufacturers 

Association) in combination with AAMA (American Architectural Manufacturers 

Association) since October 1994. This particular study details market volumes and 

trends in the U.S. for 2009, forecasted through 2013, as well as historical volumes. 

Additionally, a review of eleven U.S. regions and a top level view of the U.S. are 

presented in the Statistical Review portion of the report. 

Ducker has been conducting residential and nonresidential market studies 

continuously since 1982 for AAMA. Prior to that, studies were conducted for the Sealed 

Insulating Glass Manufacturers Association (SIGMA) since 1978. This association is 

now called the Insulating Glass Manufacturers Alliance (IGMA). Additionally, our 

research history goes back to 1972 when we first developed a demand model for flat 

glass usage in the United States. Ducker further produces many syndicated and 

custom market research studies for the fenestration and building products markets 

annually. These include the annual studies of the North American Flat Glass Market 

Study and a bi-annual study of the Northern American Fabricated Glass Market among 

many others. 

This following report is the result of a combined market study and a database 

analysis funded by AAMA and WDMA in a cooperative effort. The intent in combining 

these studies is to develop a full database and a comprehensive report on all segments 

of the window and door market. The database is designed to be utilized for studies into 

the foreseeable future and to compare ongoing trends. 

1. Methodology 

The role of Ducker Worldwide is to combine primary and secondary 

market research efforts with its own body of knowledge to profile 

and track residential and nonresidential segments of fenestration 

market volume. 

As a major input to the research, Ducker receives confidential 

disclosures from AAMA and WDMA members along with nonmembers. 

However, multiple industry sources, such as demand 

models, raw material and component suppliers, and internal 

1

databases, are necessary and consistently used to triangulate 

market statistics. Public databases are also utilized, such as the 

U.S. Bureau of Census and other sources of construction metrics. 

In addition, Ducker interviewed several hundred home builders, 

contractors, installers and distributors, which help to develop 

indicative product usage factors and channel flow as a cross 

reference to the various manufacturers’ input. 

This report, the U.S. National Statistical Review and Forecast, and 

associated regional reports were prepared by Ducker Worldwide 

LLC. Opinions and estimates constitute the best judgment as of 

the date of this material and are subject to change without notice, 

as additional information becomes available. Any interpretations 

derived from these findings are the sole responsibility of those 

using the report. Reproduction without the explicit, written consent 

of Ducker Worldwide LLC, AAMA, or the WDMA is strictly 

prohibited. 

The metrics published throughout the report represent the best 

judgment of Ducker through March of 2010; however the Census or 

other sources of construction metrics frequently do not finalize the 

totals of 2009 data until late into 2010, and they also will revise 

historical information. Ducker takes into account these historical 

revisions when updating models and thus minor differences 

between published construction data from the 2007 study may 

occur. These revisions do not impact market size estimates for 

fenestration categories unless stated throughout the report. 

Please note that while all individual numbers are accurate as 

rounded, totals may not always add due to rounding. 

The following report represents our research and analytical efforts beginning in 

late 2009. 

2. Purpose 

The purpose of this study is to provide a comprehensive single 

report detailing the window and door market for WDMA and AAMA. 

3. Methodology and Time Line 

Study findings are based upon disclosures from window and door 

manufacturers, suppliers, secondary construction data metrics and 

our prior database and experience in providing this information in 

the past. Study findings are segmented by geographic region as 

illustrated in Appendix A to this report.

The research program for the WDMA and AAMA spans from 

December 2009 through May 2010. A timeline is provided on the

4. Terminology 

Certain terms are used throughout the report which may require 

definition. Also, in our analysis, assumptions are made regarding 

units and construction activity. The following is a list of definitions 

and assumptions used in the development of this report. Specific 

questions on terminology throughout the report can also be directed 

to Ducker Worldwide, LLC. 

Bifold Door: An interior application utilizing two or more individual 

door leafs, conjoined with hinges, which operate on a sliding track. 

A bifold door is primarily a form of a closet door. However, bifold 

doors do not include folding doors or overlapping sliding doors. 

Bifold door volume counted on a per leaf basis. Included in interior 

door volume. 

Closet Doors: An interior door used for passage from room or 

hallway to closet. Included in interior door volume, but not reported 

separtately. 

3

Doors: Units are defined as actual door slabs and panels, rather 

than openings where one or more slabs would be used. Excluded 

from door units are closet doors, bifold doors and service and 

industrial doors. 

Entry Doors: A door opening that allows passage from the exterior 

of a building or home to the interior. In the residential market, 

hinged rear entrance doors connecting an attached garage to a 

home are included, while patio doors are excluded and reported 

separately. In the nonresidential market, entry doors also include 

vestibule doors. 

Flush Door Construction: A method of door construction 

whereby a thin face material is attached to a light internal frame 

(often made of wood). Face material may include high density 

fiberboard, steel, wood veneer, MDO, or other products. 

Framing: Metal, wood, fiberglass, vinyl, or composite members 

comprising the window. In operable windows, framing members 

include both a operational portion and fixed portion of the window. 

Insulating Glass: A combination of two or more panes of glass 

with a hermetically sealed air space between the panes of glass 

separated by a spacer. This space may or may not be filled with an 

inert gas, such as argon. 

Interior Door: Includes both Passageway and Closet doors. 

Nonresidential: Nonresidential construction is defined as all 

commercial buildings, from small to large, that are not meant for 

residence. Hotels, motels, and dormitories are included in 

nonresidential figures. 

Patio Doors: Units are defined as openings at the manufacturer 

level, to avoid double counting units due to multiple operable, or 

inoperable panels. For example, a double French door and a triple 

panel sliding door are all considered one unit. Figures in this report 

identify units with single panels and multiple panels alike as one 

singular unit. Further segmentation by number of panels in detailed 

in the Patio Door section of this report. 

Passageway Doors: An interior door used for passage from room 

or hallway to room. Excluded from this are garage hinged and 

service doors. 

4

Residential: Residential construction is defined as dwelling units: 

single-family attached, single-family detached, multi-family and 

manufactured homes. Apartment buildings, although considered 

commercial construction, are included in our residential figures, 

except for high rise construction which uses commercial shop 

fabricated windows. 

Stile and Rail Door Construction: A traditional method of 

construction for wood doors whereby the structural components are 

exposed. Structural components include wood stiles (vertical 

beams) and rails (horizontal beams), which encompass wood 

panels. Stiles and rails are held together using glue and dowel 

pins, while panels often “float” within channels grooved into the stile 

and rail components. 

Skylights: Standardized unit specified by product. Not included in 

window volumes. 

Sloped Glazing: Nonstandard specification, also called custom 

skylights or monumental glazing. This product is captured in 

curtainwall data, but not segmented out. Does not include 

sunrooms, which are a separate category. 

Study Regions: Eleven geographic regions are used throughout 

the report. Appendix A to this report illustrates the definition of 

these regions. 

Sunrooms: Separate classification from sloped glazing. Not 

included in window volumes, but some windows may be ultimately 

destined for use in a sunroom. 

Vision Glass Area: Unless otherwise noted, glass area figures are 

surface measure of vision glass area. Figures for spandrel glass 

materials also are surface measured. 

Windows: Units are defined as openings at the manufacturer 

level. However, the definition of a unit differs among manufacturers 

(e.g., a bay window to some may be three openings while to others 

it may be one). This does not account for multiple windows that are 

nailed together at the distributor level for one opening. Figures in 

this report more closely reflect units at the manufacturer level, 

rather than openings at the job site. Sliding and hinged patio or 

French doors are considered a separate market from windows.

2009/2010 U.S. National Statistical Review and Forecast 

Introduction 

Market estimates in the U.S. Industry Statistical Review 

and Forecast are driven not only by statistics published by 

the Census Bureau and other construction statistics 

organizations, but also from primary interviews with 

leading manufacturers of windows, doors and skylights, as 

well as component suppliers. All forecasts are based on 

projections of construction activity as of March 2009 and 

appropriate usage factors and tabulations developed by 

Ducker Worldwide LLC, which is solely responsible for the 

data. Any questions on the Review or its contents should 

be directed to Ducker. Please note that totals may not 

always add due to rounding. 

Ducker has been conducting residential and nonresidential 

market studies continuously since 1982 for the American 

Architectural Manufacturers Association (AAMA). From 

1978 to 1981, studies were conducted for the Sealed 

Insulating Glass Manufacturers Association (SIGMA- 

(currently referred to as IGMA). Ducker has been 

conducting the update study of the U.S. residential and 

nonresidential window and door markets for AAMA in 

combination with the Window and Door Manufacturers 

Association (WDMA) since October of 1994. 

The U.S. Industry Statistical Review and Forecast is 

published annually. Additional and much more detailed 

information on window, door and skylight markets is 

contained in the (2009) Study of the U.S. Market for 

Windows, Doors and Skylights, and The Distribution of 

Residential and Nonresidential Windows and Doors in the 

2009 U.S. Market, as well as individual Statistical Review 

and Forecast market overview reports for each of the 11 

major U.S. regional markets. All reports are available 

from AAMA, WDMA, or Ducker.
