Glass Block questions, answered by experts

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

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 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.

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.

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.
