Windows & Patio Doors

Old windows and patio doors doesn’t just make your house look bad, they waste energy and money. Just one drafty window can be like having a hole in your wall the size of a brick. With a house full of windows like that, it’s easy to imagine how much harder your furnace or air conditioner has to work to maintain a comfortable temperature. At Cornerstone Exteriors, we only offer Energy Star approved windows and patio doors.

  • High-performance, energy-efficient windows can offer you:
  • Quieter home interior — multiple panes and insulated frames block outside noise.
  • Reduced fading of curtains, furniture, and flooring — low-emissivity (solar window) coatings can block up to 98% of UV rays.
  • Reduced utility bills — houses lose less heat in winter and absorb less heat in summer.

Windows typically comprise 10–25% of a home’s exterior wall area, and account for 25–50% of the heating and cooling needs, depending on the climate.

Double Hung Windows

Perhaps one of the most traditional styles of windows, the double-hung window typically features the lower sash in front of the upper sash. Each sash of a double-hung window may be a solid pane of glass or may be divided into separate lights by built-in muntins or for decorative purposes, may have a snap-in, removable grid to create the illusion of separate lights. Though the double-hung window is one of the most common types of windows seen, they are valued primarily for their versatility and style. The double-hung window is available in vinyl and wood casements.

Casement WindowCasement Windows

The casement window was a popular style of window prior to the sash window. They can be found on older style Prairie and Tudor homes. A casement window is an ideal window to place above cabinets, countertops, or places that are slightly more difficult to reach because the handle mechanisms of casement windows are easy to operate. The out swing capability of the window makes it easy to clean.

Awning Windows

One of the most common examples of the awning window can be found in manufacturing plants and schools that were built between the 1920’s and 1950’s. Awning windows are designed for cross current ventilation to help cool the interior.

Picture Window

A picture window is a large fixed window that is either with or without grids. A picture window gets its name because it is designed to provide a clear view of your surroundings, acting as a picture frame for the scenery outside. Since it features a wide expanse of glass, a picture window is great for bringing natural light to your home. Adding a picture window to a room is also a wonderful way to highlight an attractive outdoor view. Most picture windows are inoperable. However, this makes them highly energy efficient. An inoperable picture window is also a smart choice for people with allergies who must take steps to limit the amount of airborne contaminants within their home.

Sliding Window

Sliding windows—sometimes called sliders—are ideal for homeowners who appreciate an unobstructed view of the outdoors. These highly energy-efficient windows are available in a myriad of configurations and with numerous options so that you can achieve precisely the look you want for your home. For ease of cleaning, the operating sashes lift out or—on select models—tilt in for easy access.

Bow WindowBay and Bow Window

A bow window is a variation of the bay window. Both types of window installations project outward from the flat surface of a wall, providing extra space and light. The bow window is named because it has a slightly curved shape, instead of the more angled shape of the bay window, and it looks like the curve of a drawn bow (one used with arrows). Like the bay window, the bow window is a lovely piece of architecture, providing extra space, access to views, or great places for houseplants that need lots of light. When there is a splendid view to be enjoyed, many people add cushioned window seats below the glass sections. This can provide greater access to views and extra seating.

Sliding Patio DoorsPatio Door

Vinyl patio doors come in a variety of styles. They are available as French doors, which many people like for their patio opening. While French doors can be more expensive than other types of patio doors, they provide an elegant look that many people enjoy.
Sliding doors are another popular style of vinyl patio doors. While sliding doors are not as elegant looking as French doors, they do have other advantages. They are easier to adjust if the ground settles underneath the patio. They also provide the same full view as the more expensive French doors.
