Q: Can you see through glass block windows at night?

• <div><p>You can still see vaguely into some types of glass block windows at night. Although there won&rsquo;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.</p></div>

Q: How do I maintain glass blocks?

• <div><p>Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.</p></div>

Q: Why is glass block so expensive?

• <div><p>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&rsquo;ll need to repair them before beginning the project, increasing your bottom line. </p></div>
