Operation Type 

Sliding windows open horizontally along tracks, making them a user-friendly option for people of all ages. Some models feature one sash (open on one end) whereas others have two (open on both ends) to provide more ventilation. They're enegy efficient as the double sashes overlap eachother when the windows closed, preventing interior air from escaping. They offer expansive views of the outdoors with minimal frame obstruction, allowing lots of natural sunlight to access the interior. Sliding windows are available in various sizes and styles to complement each home's individual charm.

Single-hung windows open vertically, featuring a movable sash on the bottom and a fixed sash on top. because these windows are only operable from the bottom, they're typically more affordable than double-hung windows. They're energy-efficient and often an ideal option for use on ground-levels.

Double-hung windows open vertically and feature movable sashes on both the top and bottom of the windows. They provide excellent ventilation and airflow control due to their ability to open at the top, bottom or both (resulting in less reliance on air conditioning systems and reduced energy bills). They tilt inward, allowing easy access to both sides of the glass from indoors, making and maintenance simple and low-effort.

Awning Windows

Awning windows have a hinged top sash and open outward from the bottom. They provide excellent ventilation and light while ensuring environmental elements like wind and rain can't access the interior. Although typically more wide than they are tall, they come in a variety of sizes and are a popular choice for areas that require ventilation but lack the space for larger windows (such as mud and laundry rooms or basements).

Casement Windows

Casement windows are hinged on one side and open outward (or sometimes inward) like a door, usually operated with a crank handle or lever. You turn a handle to open or close them, which allows for precise control of ventilation. And because there's no sash bar in the middle, they offer clear, wide views.

Picture Windows

Picture windows have a single pane of glass fixed in a frame which allows them to provide an unobstructed view of the outside. Because they're stationary and don't open, they're more energy-efficient than operable windows. They're a great choice for enjoying the scenery, increasing natural sunlight and giving an illusion of more space

Radius Windows

Radius windows are specialty-shaped windows that feature a curve or arch in their design (often in the form of a half-circle). It serves as a decorative focal point in any room and is often used to illuminate an interior with natural sunlight when installed high on the wall.

Bay & Bow Windows

Bay and bow windows both extend from the exterior wall of a house and provide more natural light and and airflow than standard windows. Bay windows are angular in shape and typically have a fixed window in the middle and two angled or boxed windows on the sides. Bow windows are curved and usually consist of four or more windows that are all the same shape and size.

Garden Windows

Garden windows are shaped like a box or rectangle and extend beyond the exterior wall of a house. They're great for those living in colder climates who want to grow plants year-round as well as, increase the ventilation in their home.
