According to a newly released study from the Window and Door Manufacturers Association, residential window shipments increased 0.2 percent in 2015 with 57.36 million units shipped across the nation. National growth is expected to increase through 2017 to 4.8 percent before trailing off in 2018 to 1.9 percent.

The WDMA 2016 Window and Patio Door U.S. Market Study provides information on residential patio door, and residential and light commercial window market trends and product relationships; historic data for 2013 and 2014; and forecast data for 2016 through 2018. Forecasts are based on projections of construction activity as of May 2016.

The study, which is based on extensive industry input for product shipments in 2015, also found that shipments of sliding patio doors grew by 8 percent on the national level over 2014. Annual growth on the national level is forecasted to moderate to 0.5 percent in 2016, 0.4 percent in 2017, and then experience a decrease of 2.2 percent in 2018. 

Hinged patio door shipments saw a rather flat annual growth rate of 0.9 percent in 2015. The forecast calls for steady declines through 2018, with annual decreases expected across the board in every division. Nationally, annual decreases of 9 percent are expected in both 2016 and 2017, and an 11 percent decrease is expected in 2018.
