The American Architectural Manufacturers Association (AAMA) and the Window and Door Manufacturers Association (WDMA) have published their annual 2008-2009 National Statistical Review and Forecast. The latest study reports a marginal share shift from wood and aluminum to vinyl-with aluminum showing the greatest decline of 26.6 percent; wood windows declined by 21.4 percent. Fiberglass windows, however, displayed an increase of 6.2 percent. The report predicts the entire window market to decline by an additional 23.9 percent in 2009, but should begin to show “marked improvement” from 2010 to 2012. The study predicts that replacement windows may receive a direct boost from the new home buyer and tax credits introduced as part of the federal stimulus plan.

Shipments of storm doors also has been on the decline-down by 4.4 million units in 2008 from 2007-an 18.5 percent drop. A further 25.5 percent decline is expected for 2009, though conditions in this area also are expected to improve in 2010 through 2012. However, the report notes, “increasing energy efficiency of entry doors and continued trends toward decorative entry doorlites may temper overall growth” in the area of storm doors.

The 2008 total patio door market declined by 18.1 percent, with the biggest drop in new construction (26.4 percent); the remodeling and replacement market only dropped 11.4 percent from prior levels. Vinyl patio doors experienced the lowest drop (15 percent) in this area; wood patio doors declined by 21.3 percent and aluminum by 25. 8 percent, according to the report.

Steel continued to top the charts in residential entry interior doors, though its market share dropped to 60 percent of entry doors in 2008, the groups report.

Fiberglass made up 28 percent of the market and wood 12 percent in 2008. By 2012, AAMA and WDMA predict that steel’s share will drop to 58 percent, while fiberglass will grow to 30 percent and wood will remain at 12 percent. Wood was top for residential interior doors—at 97 percent in 2008 and predicted to remain at that level through 2012.

The report is available for purchase in its entirety on the websites of both AAMA,, and WDMA,

AAMA and WDMA commissioned Ducker Worldwide LLC to conduct the study.
