You know your home has a personality – and we have the right windows to enhance that unique character perfectly. No other company can match Milgard's product breadth, innovation, or our passion for customer service. Being knowledgeable about your window is important. Below is a diagram highlighting the different parts of a typical Milgard window.

1. Head

The main horizontal member which forms the top of the window frame.

2. Grids

You can make standard windows and doors extraordinary with the creative use of window grids. Grid patterns placed inside the glazing unit include 5/8" wide flat grids and 1-1/16" wide sculptured pattern grids. Available for both our vinyl and fiberglass windows, these internal grids make cleaning a breeze both inside and out.

3. Hardware

Depending on the type of window you purchase, you have multiple options for the type of hardware you can install. Whether you select our patent pending Positive Action Lock™ for your horizontal slider or single hung window, or select the optional fiberglass window cam locks, you will be secure in the knowledge that our window hardware meets or exceeds the toughest forced entry codes in the nation.

4. Weather Stripping

Milgard offers weather stripping to ensure the most efficient, weather-tight seals for your windows.

5. Insulated Glass

A combination of two or more panes of glass with a hermetically sealed air space between them. Milgard windows come standard with SunCoat Low-E® coating for added energy efficiency and all around comfort, all year long. Optional argon gas may be used between panes, further improving thermal performance and energy savings.
