Glass Block Windows: Pre-fab Blocks

Reviewed by:

Glass block windows provide light and privacy but their installation can be time consuming and labor intensive. This ready-to-install prefabricated window is made with acrylic blocks which are 75% lighter than glass blocks and 35% more energy efficient.

The window's frame is vinyl with fusion welds at all joints. The window glass comes with a ten-year limited warranty. This window is also offered with an aluminum frame.

A 50" by 50" fixed vinyl frame glass block window sells for $569 (December 2005).
