Enhance Your Glass Block Window By Mixing Different Sizes And Styles

There is something very cool that is becoming more popular in the glass block world. Our industry has always been about style, because after all that’s what glass blocks are known for. Over the years the style options have increased and with the introduction of color glass blocks added a whole other dimension of utilizing glass blocks. There have been times where customers come in or call asking about what glass blocks can do for them. Sometimes they decide to get a little crazy and ask if they can use different styles of blocks, for example using our Decora pattern with our IceScapes pattern; we happily oblige each time. However, what is gaining more popularity when designing a glass block window is using different styles and different sizes of glass blocks together.

Aesthetically, glass blocks are one of a kind. Here you can see a glass block window made with 4 different sizes of glass block and 2 different styles.Glass Block Window Collage

The way the different blocks work with each other makes these already beautiful blocks that much better. This window lets in a great amount of natural light but with a level of privacy that does not cause concern. This glass block window would make a great addition to any home.

This interesting idea can be tricky to navigate because the openings need to have dimensions that allow us to use different sizes. Not only that, some styles of glass blocks like our Vue pattern only comes in 4″ thickness while our Mist pattern only comes in 3″ thickness. Both the we and the customer have to be keen in knowing which blocks can be used with one another during the design phase. Glass blocks are inherently eye-catchers so when a window has different shapes and styles it is much more noticeable.

Here you can see another glass block window using 2 different styles (IceScapes and Decora) and 2 different sizes (4″ x 8″ and 8″ x 8″) of block.

We love getting customer inquiries about windows like these because it’s fun to sketch up an idea that the customer really enjoys and wants to go ahead with. We are eager to accept the challenge of filling out any dimensions using different styles and sizes are you see above.

And here is one of my personal favorites: This window was made with 2 different sizes of block (12″ x 12″ and 6″ x 6″) and 3 different styles of block (Decora, IceScapes and Decora LX).

How Glass Block Basement Windows Can Improve Your Home

There are a high number of homes who are victim to unfriendly basement windows. Water gets in and floods the basement, mold and mildew form, it starts to smell and insulation is something they always give up on. There is a solution to all of these negative attributes associated with single pane basement windows; glass block basement windows. These windows can be prefabricated and built at your house like traditional bricks. They can also have a vent installed in them to offer you the opportunity to let fresh air in.

A customer last week, Theresa, inquired about a glass block basement window because her basement was dark and damp, despite it being clean. I explained how glass block basement windows can brighten up the place while offering other added benefits. She was thrilled when I told her they prevent water from entering the house unlike single pane windows and said “That would solve more than one problem because my basement windows also leak.” Theresa was satisfied knowing how this product can improve her home in many ways.

Glass block basement windows offer much more than traditional basement windows. For example, traditional windows are easily broken and broken into, frequently leak, have poor insulation and do not require constant maintenance. When compared to a glass block window, single pane windows don’t stand a chance. It is very easy to break a regular window, but not easy to damage a glass block window. This alone can deter criminals from trying to enter your home and protect you from kicked up rocks or playing kids. Single pane windows often leak which can ruin the things you keep in the basement and even the home’s foundation. Too many times we have seen and heard people coming in and telling us they have tried other alternatives for the basement windows only to eventually tell us none of those worked.

Glass blocks are also great insulators. They keep the inside air from escaping and the outside air where it belongs, outside. Not only for basement use, glass block windows save you a lot of money on heating and cooling bills for the changing seasons. There is also a factor of maintaining your basement windows. Small curtains are typically on the inside of basement windows to keep privacy high, but this also blocks out sunlight coming in. Additionally, this can make traditional windows require even more cleaning. Glass blocks inherently have high levels of privacy without needing curtains. What’s more, the sunlight still gets through so the basement isn’t a dark place desperately needing artificial light.

Glass Block Assembly: Mortar vs. Silicone

Glass blocks are architecturally like regular bricks. They are both used in the same way only glass blocks can be used in places where traditional bricks can’t. Similarly, these two products are commonly put together in the same fashion; using mortar. However, there are some applications where silicone might be a preferable choice over mortar. This article will delve into glass block assembly using either technique.


When constructing something with glass blocks, mortar is the go-to option. Mortar looks the most traditional and when the product has a chance of being hit by constant water, such as a shower, it’s the one to choose. With silicone, there is a chance water can creep its way in between the joints and loosen up the bond if improperly installed. Mortar withstands all types of weather and holds strong and true for a very long time. You can also makes the joints bigger or smaller to fit the opening better which can’t be done with silicone. There are also many different silicones available to use for glass blocks which can cause much unwanted confusion. There is mortar specifically made for glass block use that is the gold standard in the industry. Glass Block Showr With Style Caps

Another reason to choose mortar over our structural glazing sealant would be if you had to abide by building codes or commercial applications. Most commercial applications need to pass fire codes and mortar will be the only choice in this case. Common applications of glass blocks with mortar are showers, exterior windows, partitions, walls, basement windows and entryways. Glass Block Basement Window


If you want a cleaner look for a glass block application than silicone might be right for you. When using our structural glazing sealant, it requires much less work to put the window, partition or wall together as opposed to the steps needed for mortar. Silicone is used mostly when an all glass look is preferred instead of having visible mortar joints that resemble what you see in tile floors or brick walls. The joints are obviously smaller, less visible and allow more light passing through when compared to a mortar-made product. It is also much easier to apply; you can do it with a caulking gun.

If the space where the glass blocks are going is small, silicone might be the preferred choice since the joints are smaller which makes the entire product smaller than it would be with mortar. Some people might just prefer silicone over mortar solely on looks without any architectural reasons. Applications such as hurricane and tornado walls made with glass block are constructed with structural glazing sealant. The reason for this is it allows the product to give and take with the high force winds instead of standing without moving. Structural glazing sealant allows the product to “bend” with the strong winds. Glass Block Window

Glass blocks done with either process can be pre-assembled or built on site and both processes can also be assembled with or without a frame. Common applications of glass blocks with silicone are partitions, interior windows or panels, kitchen backsplashes and basement windows.
