Unique Characteristics of Glass Block
Selecting windows for your home or building project may seem like a minute detail; but in actuality, it is a very important decision. Not only are windows very important to the overall design of the project both on the interior and the exterior, but they play a major role in temperature control as well as interior lighting. There are some intriguing ways to bring style and sophistication, while meeting the practical requirements of the windows. One of these clever designs is the use of the glass block window.
What are glass blocks?
Glass block windows are literally glass blocks that can either stand alone as an accent window, or combined to form one large window. Typically frosted or with some form of thick, decorative glass, they work well as a privacy glass while still allowing light to pass through.
Where can they be used?
Block windows can be placed pretty much anywhere you desire; however, the most common locations are bathrooms, transoms, sidelights, or kitchens. They have even been incorporated into the walls of a shower or bathtub enclosure.
What are the characteristics of a glass block?
The actual blocks range in size from 4”-9”, and are normally around 3” thick. They can be made out of acrylic or glass, and many are glazed for additional energy efficiency. When encased in standard frames, installation is very similar to standard windows.
As illustrated in these pictures, there are many beautiful ways to incorporate glass block windows into your design. The windows come in many of the standard models, including casement, awning, single-hung, and sliders. The frames can consist of a range of decorative materials, and when paired with quality hardware, a very custom appearance is created.
