Glass Block questions, answered by experts

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.

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.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

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.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.
