Ply Gem Windows developed the 1500 Vinyl Collection to simplify product selection. The line consolidated single hung, sliding, picture and architectural shape styles into one platform with common sash and common sizing. Customizing windows became streamlined by first choosing from the three frame options of brickmould, beveled and flat. Then, select a color from white, beige and clay. Lastly, configure windows’ energy efficiency levels based on market needs, customer preferences and climate zone.
