Glass Block questions, answered by experts

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

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 walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.

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.

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