Ducker Report Shows Stable Growth

Findings from the 2004 U.S. Industry Statistical Review and Forecast by Ducker Research Co. Inc. of Bloomfield Hills, Mich., are now available and reveal that most door and windows specification sectors are on the upswing. The report is co-published by the Window and Door Manufacturers Association (WDMA) of Des Plaines, Ill., and the American Architectural Manufacturers Association (AAMA) of Schaumburg, Ill.

Residential doors, windows and patio doors benefited from strong remodeling and residential improvement markets and, according to the study, home improvement expenditures are forecast to have increased 3.4 percent in 2005 over 2004 levels. Driven by continued low interest rates and increased home improvement projects, residential improvement expenditures rose by 5.6 percent. 

The study also revealed that the residential prime window market grew by nearly 7 percent to reach 67.1 million units in 2004. Vinyl continued to grow in 2004, by 11.7 percent. Wood sales grew by 2.4 percent, while aluminum declined 1.7 percent. (The residential window market is divided into four categories based on the predominant frame and sash materials: wood, including clad, vinyl, aluminum and fiberglass.) 

Both fiberglass and other composites remain a small, but quickly growing, portion of the overall market. Fiberglass grew by nearly 30 percent from 2003 to 2004, and the study stated that “as window manufacturers continue to explore new materials and invest in production capabilities, these materials will continue to grow.”

Although patio doors are primarily produced by window manufacturers, traditional door producers have also entered this market and are growing their share of wood, steel and fiberglass units. 

The residential entry door market showed strong growth in 2004, where unit volume increased by 5.1 percent to 14.5 million entry door units. 

The report is available from WDMA, AAMA or Ducker. Any questions on the review or its contents should be directed to Ducker Research Co. at www.ducker.com.
