The purpose of this study is to: 

• Develop baseline information on market penetration of <U-35 window and patio door and <U-45 skylight estimates in the four Northwest states.
• Characterize the manufacture, distribution, and purchase patterns of windows, patio doors, and skylights in the four Northwest states.
• Identify and discuss factors influencing window and skylight purchases.

This study presents baseline information on the market penetration of U-35 windows, U-35 patio doors, and U-45 skylight estimates in the Pacific Northwest. Information came from surveys of window, door, and skylight manufacturers; high-volume builders of single and multifamily units; retailers of windows, patio doors, and skylights; and builders in the high-end remodeling business.
