Q: What do you do if a glass block breaks?

• <div><p>Although glass block windows are made of multiple layers of thick glass, they&rsquo;re still susceptible to breaking. If your glass block window shatters, contact a window repair professional to remove and replace the glass block. Don&rsquo;t attempt to handle it yourself because the broken glass can be dangerously sharp. A window repair pro will have the tools and expertise to replace the broken glass block quickly. Before hiring, be sure to confirm the repair pro has experience with repairing or replacing that specific type of window.</p></div>

Q: What are the benefits of glass block windows?

• <div><p>If you like to be certain of your privacy at home, glass block windows might be your match. They offer privacy without preventing light from entering, while also providing enhanced security. Plus, they <a href="https://www.angi.com/articles/4-steps-improve-home-energy-efficiency.htm">increase your home&rsquo;s energy efficiency</a>.</p></div>

Q: What kind of mortar do you use for glass block windows?

• <div><p>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.</p></div>

Q: How are glass blocks energy efficient?

• <div><p>Glass blocks are much thicker than glass panes in traditional windows and serve as better insulators. The overall glass block window is sealed against drafts that allow warm or cool air to escape, saving on energy costs. Since this type of window is sealed airtight into your home, you don&rsquo;t have to worry about air leaks and drafts as often as traditional windows that open and close. When installing glass block windows, look for options that are Energy Star rated, proving their energy efficiency.</p></div>
