AW11 UnitType Awning Window

Awning Windows

Awning windows are hinged on the top and open outward from the bottom, allowing for ventilation and protection from the rain. Often placed higher on walls for privacy or combined with other windows for a better view.

AW11 UnitType Bay Window

Bay and Bow Windows

Bay and bow windows are created by combining three or more windows together so that they angle out beyond the house wall, allowing more light in and giving you extra space inside your room.

AW11 UnitType Casement Window

Casement Windows

Casement windows crank open outward to the left or right allowing for full top to bottom ventilation. Common above kitchen sinks, casement windows give you the flexibility to group them in stunning combinations.

AW11 UnitType DoubleHung Window

Single & Double-Hung Windows

Double-hung windows have two sash that move up and down allowing for maximum ventilation. Single-hung windows allow ventilation through the lower sash. Both offer easy cleaning from inside your home and remain flush with the wall, making them ideal for patios or walkways.

AW11 UnitType Gliding Window

Gliding Windows

Gliding windows operate in a horizontal fashion to allow for full top to bottom ventilation. Because they don’t open outward they are an excellent choice for rooms that face walkways, porches or decks.

AW11 UnitType Stationary Window

Picture Windows

Picture windows are stationary and do not open. This makes them more energy efficient and allows for larger sizes than a window that vents. Often used in combinations to maximize the view.

AW11 UnitType Specialty Window

Specialty Shape Windows

Specialty shape windows let you choose from a variety of uncommon shapes, including elegant arches, striking angles and compelling curves.

Andersen Windows and Doors

Andersen Windows was founded in 1903, and one of the main reasons we sell Andersen windows and doors is because of the company’s longevity – Andersen isn’t going away anytime soon.

Andersen provides a wide selection of quality windows and doors at affordable prices, which are protected by a good warranty.

Andersen Storm Windows and Doors

Pittsburgh and the southwest corner of Pennsylvania may not be on the coast, but we do get our own severe weather. Andersen’s Stormwatch® storm windows and doors offer extra protection from the elements to stand the test of time. They are warranted against corrosion, and are available in classical architectural styles.

Andersen Conversion Kits

Andersen Windows also offers window conversion kits that allow you to upgrade the windows in older homes, especially ones built in the 1960’s and 70’s, to take advantage of modern features such as windows that tilt in for easy cleaning, and high-performance glass. Unless they work frequently with Andersen, most window installation contractors are not aware of these Andersen retrofit kits, but we use them on Andersen replacement windows projects frequently.
