Glass Block

Glass Block is a building product that’s been around for more than a half-century.  It’s considered masonry and was originally reserved for commercial applications where light transmittal was required without sacrificing durability and security.

Glass Block Windows

In the early 80’s, we started promoting the idea of glass block for windows for residential projects.  It was a natural fit for basement windows and we’ve installed more than 250,000 of them and more than 100,000 residential projects in our 40 years.


There’s no denying that more glass block is used for basement windows in the US than any other application.  We install over 2,000 residential contracts each year ourselves! They’re the ideal basement window.  They’re weather proof, let in light, and are absolutely secure.  There’s no better option for the least traveled space in your home!


“Privacy” only partially describes the reason for glass block in a bathroom window.  “Privacy without the need for curtains or blinds” is a better description.  Not to mention the fact that our glass block bathroom windows are virtually maintenance free and can be cleaned with any cleaner you would use on your tile, unlike some of the plastic block windows on the market.


Lawn mowers, tools, toys, bikes, and any number of other things that a thief would be eager to get their hands on are stored in your garage.  Usually, your home security system starts at the door from the garage to the house.  If a thief can’t see what’s in there to steal, he won’t suffer the embarrassment of failing to get through our glass block window.  Basically, keep out the prying eyes and the bodies their attached to!

Vents & Accessories

Ventilation, Dryer Vents, even cat doors can be installed in our glass block windows.  Typically these things only take the place of a couple of the blocks in the window so the security aspect is not affected.  Get fresh air in, dryer exhaust out, cats out, or squirrels in.  Piece of cake!

Walls & Showers

The 2nd most popular use of glass block in a residential application is in showers.  Rather than more tile, walls are constructed from glass block.  The effect is a less “dungeonous” shower stall where the shared light makes the stall feel bigger.

Standard Walls

Dividing rooms with glass block will make the rooms feel bigger than they really are.  Various transparency options and even colors are available to maintain whichever level of privacy your project requires.

3d Shape Walls

Want to add another dimension to your dividing or exterior wall?  We have several patterns that include blocks with 22.5° and 90° corners, and even radius shaped blocks in their selection.  Serpentine walls, or simple 90° turns are easy! 

Custom Designs

Want something truly unique?  We have the largest selection of colors, patterns, and finishes available in the glass block world through SEVES.  Checker boards, flutes, waves, and even mixing different sizes together with or without color can make a truly unique wall!

Etched Block Walls

Unique on a whole new level!  Can’t find the glass block pattern that suits your décor?  How about a wall or window with a custom laser engraved scene spread across the entire window?  Mountains, ocean, forest, or perhaps something more personal like your favorite team, cause, or even family?  We can engrave virtually any image, graphic, or text onto either individual blocks, or spread over the entire window or wall!

Secure Your Basement with Glass Block Windows

When it comes to fortifying your basement against potential security threats, glass block windows stand out as an exceptional choice. Unlike traditional basement windows, which can be vulnerable entry points for intruders, glass block windows offer enhanced security features. Crafted from durable materials and sealed with precision, these windows provide a sturdy barrier that deters unauthorized access. Their solid construction makes them resistant to break-ins, offering homeowners peace of mind knowing their basement is safeguarded against unwanted intrusions.

One of the key advantages of glass block windows in basement security lies in their design. With their thick, transparent panes, these windows allow natural light to illuminate the basement space while maintaining privacy and security. Their solid construction makes them difficult to tamper with, making it challenging for potential intruders to breach. Additionally, the sealed nature of glass block windows prevents unwanted drafts and moisture infiltration, further enhancing the security and comfort of the basement environment.

Moreover, while prioritizing security, glass block windows also offer flexibility in ventilation and opening options. Despite their sturdy construction, they can be customized to include vents or openings, allowing for controlled airflow and increased comfort within the basement environment. These ventilation features are designed with security in mind, incorporating mechanisms that maintain the integrity of the window’s seal while providing adequate airflow. Whether you prefer a fixed design for maximum security or opt for ventilation options, glass block windows ensure that your basement remains both secure and well-ventilated, catering to your specific needs without compromising safety.
