Glass block windows are geometrically patterned squares of glass usually texturized for privacy. They can either stand alone as an accent window, or combine to form one large window. Many homeowners are drawn to glass block windows because they offer additional natural lighting without compromising privacy. Interested in them for your own home? Here’s what you need to know.
On average, a 32”x42” glass block window will cost around $500 after installation. For more specific cost estimates, talk to a local window contractor in your area.
Since glass block windows cannot be opened and are made from rather thick glass, they are an extremely durable window option.
In addition to be durability, glass block windows are also virtually maintenance-free. Occasionally wipe them down with soft cloth and a household glass cleaner—it’s really that easy.
Glass 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.
The actual blocks range in size from 4” to 9” and are normally around 3” thick. They can be made out of acrylic or glass, and many are glazed for additional energy efficiency. They even come in a variety of models, including casement, awning, single-hung, and sliders.
Glass blocks were first used in the early 1800s to provide additional lighting in cellars and ships. They became extremely popular in the 1950s and ‘60s during the art deco movement and are still used in many homes today.
