Standard Grids

  • Standard Grids – also known as Colonial grids, these are the popular squares that work well in traditional or contemporary styles.  Standard grids can be used on the whole window or door, just on the top sash. You can also specify the number of lites across and up/down, depending on the size of the glass.

Valence Grids

  • Valance Grids – Valance grids are similar to the Standard grids but are only across the top of the window or door. Like Standard grids, you can specify the number of lites across and the height. 

Perimeter Grids

  • Perimeter Grids – For an attractive contemporary look, consider Perimeter grids which provide an outline on the perimeter of the glass with the grid intersecting in the corners.  Perimeter grids offer an even broader choice of patterns because you can specify a perimeter on each window, on just a sash or a perimeter across an array of windows and/or doors.  You can have the grid intersection only at the top or in all 4 corners.  


Low-E Glass Coatings

  • SunCoat® Low-E2 Glass

    This microscopically thin coating is applied to one side of the glass to reflect heat from its source in the summer, keep heat inside in the winter and reduce harmful UV rays. SunCoat Low-E2 glass comes standard on all Milgard dual-pane windows and patio doors.


    Consistent temperatures for greater year-round comfort = Energy savings

    Reduces harmful UV rays by up to 84 percent = Helping protect fabrics and carpet from the sun's damaging rays.

  • SunCoatMAX® Low-E3 Glass

    SunCoatMAX Low-E glass provides the best clarity and highest performance of all solar gain Low-E glass products.


    Increases center glass surface temperature in winter = Comfortable, consistently cozy rooms.


    Reduces solar heat gain more than two-coat, Low-E glass = Keeps your house cooler in the summer.


    Provides ultraviolet light blockage = Additional protection from UV-A and UV-B rays for your fabrics and other furnishings.
