Our fully customizable glass block windows are prefabricated, and hand crafted together using a vinyl spacer between each block and adhered with silicone. Encased in a vinyl frame with an attached nail fin for easy installation, our real glass block windows are the ideal application for any construction project.
When choosing your window design, one of the first steps is to determine the opening and size of the window you desire. Stevens Glass Block offers both Imperial and Metric blocks that will vary the rough opening and overall size. Secondly you may choose the pattern that fits your requirements such as privacy, decorative design and or light transmission. Then you can choose one of the two frame color options we have to offer, Almond or White. Once you have all the details in place, you are ready to proceed in having Stevens Glass Block produce a prefabricated custom glass block window of your design. *Due to weigh limitations, some window sizes are unavailable for prefabrication and must be installed loosely on site.


Almond frame color also known as Beige or Sandstone
