Get matched with top glass block pros in your area

Glass blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.

You can still see vaguely into some types of glass block windows at night. Although there won’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.

Glass block windows come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

Although glass block windows are made of multiple layers of thick glass, they’re still susceptible to breaking. If your glass block window shatters, contact a window repair professional to remove and replace the glass block. Don’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.
