Glass Block questions, answered by experts

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.

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.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

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 mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.
