Each year, the Window and Door Manufacturers Association partners with the Farnsworth Group, a market research provider in the building materials, hardware and home improvement industries, to survey architects, builders and remodelers. One of the goals of this partnership is to gain an understanding of how past shipments of windows, doors and skylights will inform future growth.

The Farnsworth Group used various sources to determine the 2018 market sizes and forecast future growth through 2021. In addition to member data collection and other research methods, the organization conducted primary channel research with 287 retailers, including big boxes, home centers, LBM dealers, and specialty suppliers, and primary end user research with 150 home builders, 150 GCs and remodelers, and 99 window and door installers.

The findings revealed a number of interesting insights on what the future may hold.

Shipments are expected to increase over the next three years, but forecast to slow down each year to a growth rate of 2.2% in 2021.
