40% more daylight than comparable wide-frame windows

DaylightMax is engineered around one idea: more glass. Its slim 2-7/8″ frame trims away the bulky vinyl other windows hide behind, opening up the viewing area and pouring natural light into every room. Brighter spaces, bigger views, and a clean modern profile that disappears into the architecture.

  • Narrow 2-7/8″ frame maximizes glass area and the view
  • About 40% more glass than Brand X in a 31″ × 21″ picture window
  • Dramatic black & bronze laminate options, inside and out
  • Good Housekeeping Seal on the DaylightMax sliding window

Thin where it counts. A slimmer sightline means a bigger pane of glass in the same opening — so you see more sky, not more frame.

The DaylightMax Collection

One slim look, every opening.

DaylightMax comes in nine window styles, so you can carry the same narrow-frame look and natural light from the living room to the bath, the kitchen, and beyond.
