Plastic Windows to Grow 5.5% Annually Through 2021

CLEVELAND, June 22, 2017 /PRNewswire/ — Demand for plastic windows is forecast to rise 5.5% per year to $6.5 billion in 2021, outpacing wood and metal windows and accounting for half of total sales. Home and business owners will continue to specify vinyl windows for their energy efficiency, low cost, and low maintenance. Specialty plastic windows are projected to see above average gains, spurred by increased demand for skylights, roof windows, and customized shapes. Fiberglass and wood-plastic composite products are expected to gain share, although vinyl will continue to represent over 90% of sales. These and other trends are presented in Windows Market in the US, a new study from The Freedonia Group, a Cleveland-based industry research firm.

Plastic windows saw much faster penetration of residential (versus commercial) markets through 2016, primarily displacing wood products. Through 2021, the residential market for plastic windows is projected to advance 5.7% per year to $5.8 billion, outpacing 4.0% yearly gains in the commercial segment.  According to analyst Carolyn Zulandt, “The residential market will continue to account for nearly 90% of plastic window sales, as builders of commercial structures rely more heavily on metal products for their superior durability and security.”  However, vinyl and fiberglass windows have displaced many wood windows used in offices, retail structures, and such structures as hotels and educational facilities.
