Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.
