Timeless Design

  • Essence Series windows offer seemingly endless design possibilities. The fiberglass exterior comes in 16 designer colors that fit any style or trend. 

    Interiors are available in clear vertical grain fir, natural pine or primed pine. Seal or stain the natural pine or fir to complement the wood finishes in your home. Or go with primed wood and paint the color of your choice.

    Because Essence Series has an innovative mulling system, there’s virtually no limit to window combinations. 

    Picture windows are available in casement/awning and double hung/glider frames that create a clean, consistent look when used with the matching operating style. 

    The design of each of these combinations will create even sight lines throughout your home.

Innovative Engineering

  • Exceptional Quality

    Essence windows are not merely a ‘fiberglass-clad’ wood product, but a true wood window enveloped by a tough, durable fiberglass frame. Milgard's secure connecting system firmly joins the wood interior frame to its fiberglass exterior frame for an aesthetically superior appearance with no unsightly nail holes or staples.

    Essence Series fiberglass exteriors are resistant to water, cold, heat, insects, salt air and ultraviolet rays for long-lasting performance and low-maintenance. The powder-coated fiberglass exterior finish won’t crack, peel, bend, warp or stick due to expansion and contraction.

    Every Essence Series window and patio door is designed and assembled in the U.S. and custom made to exact size and specifications.

  • Mulling

    Essence Series windows use a newly engineered mulling system that more securely connects multiple units, creating a tight seal and protecting against air and water infiltration. 

  • Water Management

    Milgard developed a new, advanced water management system, exclusive to Essence Series windows. In the rare event that water enters the sash system, it is directed away from the beautiful wood interior. This allows the window to perform at a higher design pressure than most other wood windows, making Essence windows ideal for all conditions.

High Standards, Quality Finishes

  • As one of the largest and most trusted window and door manufacturers in the country, Milgard makes sure to only use quality parts and finishes. Every piece of your window or door is held to the highest brand standards.

    To assure quality and long-lasting performance Milgard fiberglass frames are tested for color uniformity, gloss, film thickness, and chemical resistance. 

    Ultra Series
    Ultra Series uses a powder coat finish on Harmony, Bark, and Black Bean when the exterior and interior are the same color. Otherwise, they are painted with a wet coat application.

    Essence Series
    Paint is applied using the latest advances in powder coat finishing technology, it's the same technology used in aerospace and automotive applications. Essence finishes are more durable than conventional finishes and provide increased protection against fading, chipping, and scrapes. 


Hardware Options

  • Folding Nesting Operator Handle

  • Sash Lock


Grid Options

  • 5/8" Flat
  • 1-1/16" Sculptured
  • 1-1/8" Standard Vintage
  • 3/4" Narrow Vintage

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.
