Studio Windows

The studio window is designed to compliment an operating unit as a mulled combination or they can stand alone. Because studios are often fairly large windows, they add a sense of openness to a room and often times are positioned for a great view of the outdoors.

Timeline constructs fixed studio windows as a direct set or in a sash and frame design. This is a perfect unit for commercial projects when venting is not required or the window is inconvenient to reach. Non-operable windows are also very energy efficient.




With taller ceiling heights and the popularity of great rooms, you need your windows and patio doors to look and feel in proportion to the design. You can always go with a taller window or door, but transoms offer an exceptional design opportunity. Not only do you get the benefit of more light, you add a key architectural element to your room.

Transoms may be split to align with the window or patio door configuration or can be a one-piece design that extends over the entire span. Our transoms are made to exacting standards and can be built with narrow and wide stiles to maintain site lines. When looking for a little extra style or flair, transoms are a simple and attractive solution for your taller window and patio door requirements.



Shaped Windows

Be exciting, distinctive and even a little daring by incorporating a curved shape into your next project! Choose an elegant half round style as the focal point of your elevation or an elliptical or a…well you get the idea. And that’s just a small sample of what Timeline’s specialty department can do.

Timeline specialty shapes are crafted from a CAD template and built as a direct set frame or a sash and frame style. Interior trim is shaped to fit the window radius, molded to your profile and provide superb fit and finish.



Direct Set

A direct set shape is best described by installing a piece of insulated glass ‘directly’ into its frame. This is the most cost effective means to purchasing a non-operating window. Timeline direct set windows can be built in every shape we offer including radius products and geometric shapes.

Direct sets are custom-sized windows and can include: many grille types, ten interior trim profiles, applied jamb extensions in six wood species and all glass options.



Sash Set

A sash set Timeline window employs a heavier look by adding a sash component with-in a frame (glass is glazed into a sash which is then installed into a frame). This design complements our operating units and is commonly used in combinations because glass sightlines match better.

Architecturally, a sash set is usually favored for its enhanced aesthetics. This type of window construction is both appealing and functional. View our options section for additional features such as: exterior trims, grilles, interior casing, colors and our many glass choices.
