Important Warnings!

Shower Doors are Not Watertight

Cardinal Shower Enclosures, when properly installed, are designed to prevent leaks under normal shower conditions. Excessive water pressure or directing the shower spray directly at the door do not represent normal shower conditions and can result in leaks.

Frame Cleaning

Have a little dirt or a smudge on one of your frames? No problem. You can wash it with mild, nonabrasive soap and water. Never use abrasive or acidic cleaners—they might cause permanent damage to the frame finish. Always test cleaners in an inconspicuous area first. Wipe dry when finished.

Glass Care

Milgard controls the entire production of every window and patio door—including the glass. Whether your window comes with the standard energy-efficient SunCoat® Low-E glass or with one of our many specialty glass options, an occasional cleaning is necessary to ensure clarity and exceptional performance.

Components of an Energy-Efficient Window

What's an energy-efficient window? Most will have at a minimum:

  • Double-pane insulated glass
  • Heat-resistant (Low-E) glass coating
  • Airtight frames
  • ENERGY STAR® rating

Three Dimensions of Energy Efficient Window Design—An energy-efficient window is a synergy of its components. At Milgard®, we call this the "three dimensions of energy efficient window design." Here's what you should look for in each of the three dimensions: glass, spacer and frame.

New Construction Window

The NFRC Label

New construction windows typically have a nail fin. When homes are built, the framing is likely constructed of wood studs. The nail fin rests against the outside of the stud, and nails or screws are driven through the holes in the fin. All other exterior materials are then applied and butted up to the frame of the window or trim.

New construction windows also can be used in a replacement project. The exterior materials, such as window trim (if it exists), siding, stucco or flashing, are removed, exposing the wood studs. The new window is then installed as it would have been when the home was originally built. Exposing the original studs also allows your contractor to see potential damage (typically rot) or home settling that may have occurred. The damage can be repaired, and the new window installed with proper insulation to minimize air infiltration between the new window and the studs. As you can imagine, this method can be more time consuming so often costs more than other replacement methods.
