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.

Not only does this limit creativity, in the eyes of the homeowner it can leave something to be desired. There are materials available which are not only decorative in nature, but also equally as useful in architectural designs. One specific product that meets both qualities is colored glass blocks. Below I will highlight this product.

Colored glass blocks can turn your typical home into one that stands out. Additionally, glass blocks can be used inside and outside. Like clear glass blocks, which are also commonly used in residential applications, colored glass blocks come in a variety of sizes to fit your needs. Color glass blocks are more aesthetic and can really boost the look of your home décor, something regular glass, bricks, tiles or granite can’t do. If you think color glass blocks are only good being used for strictly decorative purposes then here is something you should know: Glass blocks are great for being used architecturally as well.Glass Block Color Window

Basic clear and colored glass blocks are the same in terms of strength and safety which means they both can be used for building without fear of using a weaker product. These blocks are frequently used to build showers, partitions, windows, kitchen islands and backsplashes and even as the sidelight for the entry of a house. You can use these colored blocks in an existing wall to match your décor or make an entire colored wall. If you are considering an exterior color wall, but are concerned about privacy, fear not. Glass blocks are available in high privacy patterns. Whether you are remodeling the interior or designing a new home from scratch, color glass blocks can be a great addition, setting the stage for the color scheme you choose.
