Glass Block Windows questions, answered by experts

If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Glass block windows cost about $710 to install, ranging from $460 to $980. The cost factors of installing this type of specialty window include the opening size, design, layout, height, glass block type, installation type, and location. There are many block styles to choose from, including colored, clear, wavy, diamond, and frosted.

  • 25-by-25 inches: $60–$300

  • 31-by-31 inches: $65–$350

  • 36-by-36 inches: $85–$475
