What is Glass Block Divider Wall

A glass block divider wall is a wall made of glass blocks. The blocks are made of glass, and they’re used to divide space in an apartment or house. They can be used for decoration too.

They can be found in kitchens, bathrooms, and other areas where you might want to divide up space without blocking light out (e.g., your bedroom).

Uses of Glass Block Divider Wall

  • Glass blocks can be used as a divider wall for creating separate spaces in your home.
  • Glass blocks can also be used as a privacy wall, which offers you and your family the privacy that is needed in any given room.
  • You can use it to create various unique designs on your walls without having to worry about painting it over again every few months or so.
  • It will give you the impression that you are living in an apartment with high-end features even though it might just be an old house that needs some renovation and remodeling work done on it.

Reasons for installing Glass Block Divider Wall

  • Glass block walls are very durable.
  • Glass block walls are low maintenance.
  • They can be used in a variety of ways, including:
  • Privacy walls and sound barriers
  • Fireplaces and heaters
  • Decorative features in the home

Steps involved in building Glass Block Divider Wall

  • Block the wall.
  • Install the cement board.
  • Apply the silicone caulk to all joints and edges of the blocks, being careful not to get any on top or inside of your glass blocks.
  • Apply grout to each joint with a grout float to fill in any gaps between your block pieces and smooth out any rough spots on your surface. Let it dry for about 20 minutes before removing excess with a clean damp cloth so you don’t smear it around, which could take away from your final results.
  • Install glass block on top of installed mortar bed with stainless steel screws provided by the manufacturer (usually attached). Make sure they’re long enough so they won’t go through the divider wall’s framing members (if any), but short enough that they won’t protrude too much into the tub area where people will be standing/walking on them during the installation process.

Tools needed for Glass Block Divider Wall

  • Tape measure.
  • Utility knife.
  • Level.
  • Nail gun (if you’re using this to hold the glass blocks in place). Notice that a nail gun will also come in handy for attaching cement board to your studs because it can drive wood screws through many layers of material very quickly and easily. If you don’t have access to one, you can use a hammer and nails instead but it may take longer and be more difficult than using the power tool would be.
  • Caulking gun (to seal between each row of glass block).
  • Brick hammer (for chipping away old mortar if necessary). A regular claw hammer won’t work because it doesn’t have enough mass or weight behind its head; you want something heavy enough that when you strike down on something with it, it’ll make an impression on whatever surface needs some attention like concrete or mortar. Be sure to wear safety glasses when using this tool.

Materials needed for Glass Block Divider Wall

To create this glass block divider wall, you will need:

  • Glass block
  • Cement board (like Durock) for the back of the divider wall. This is not required but it’s easier to cut and install if you use cement board as opposed to drywall. It also allows for more moisture absorption than drywall does.
  • Grout will be used to fill in any small spaces between the glass blocks when they are installed. We recommend using clear grout so you can see through it. But we would love it if someone tried this project with colored grout too.
  • Silicone caulk or another waterproof sealant (like Dap 3-in-1 Waterproofing Sealant) will be used to seal around the gap between each piece of glass block on both sides of the divider wall (backside at the top and bottom). The silicone will help keep moisture out which could cause damage over time if left exposed without protection from water infiltration into your home/office building structure like walls made out of concrete blocks or cinderblocks without sealing off their insides with something like Polyurethane foam insulation plus vapour barrier sheeting – so make sure those gaps are filled up tight before installing your new glass block panels; otherwise, water can get behind them too easily causing mold growth on wood framing members inside these kinds buildings due high humidity levels within them being trapped there long term due lack good ventilation systems working properly during hot humid summer months where temperatures rise high enough outside ground level temperatures soar well above 100 degrees Fahrenheit every morning during lunchtime hours causing sweat condensation buildup inside underfloor areas where people walk around wearing only sandals all day long during daytime hours when temperatures rise even higher than before.

Glass block

When it comes to building a wall, a glass block is an excellent choice. It’s lightweight and easy to install, plus it’s easy-peasy to clean. It can also be cut, painted, or drilled as needed.

Cement board

A cement board is a manmade material made from cement, lime, and sand. It’s used as an alternative to drywall for interior walls because it’s thicker and more durable, but not quite as strong as steel studs. Cement boards can be purchased in sheets at your local home improvement store.

You’ll need a saw to cut the cement board before installing it into your wall; most people use a circular saw with a blade designed for cement or masonry materials. You’ll need to wear ear protection when cutting so you don’t damage your hearing while wearing headphones or listening devices (like Beats). Make sure that all of the dust is cleaned off your tools when they’re done cutting so you don’t get cut on any leftover slivers of metal left behind by your tool’s blade.


The grout you choose for your glass block wall should be a mixture of cement and sand, which will fill in the gaps between the glass blocks. This will ensure that your entire wall is firmly attached to each other.

The correct amount of grout depends on how thick it is. You can test this by placing a small amount on top of a clean towel, then pressing down with your finger (don’t press too hard). If there’s still space between the glass blocks after pressing down, then you need more grout.

Silicone caulk

You’ve heard of silicone caulk, but do you know what it is or how to use it? It’s a great addition to your glass block wall project because it can help keep water out and make the wall look more finished. Here’s how:

  • Silicone caulk is a sealant that fills in cracks and gaps between glass blocks. This helps prevent water from getting into your home through those cracks, keeping mold away from your walls. The best way to apply silicone caulk is with an angle grinder (or just a stick). You’ll want to apply a small amount at a time so that if you need more than one coat you won’t have too much product left over at the end of the job.
  • After applying silicone caulk around all sides of each block, use a wet rag or sponge dipped in warm water and wipe off any excess material before letting it dry overnight (so there are no bubbles). Make sure not to get any moisture inside.


Sandpaper is the best way to smooth out the surface of the glass and make it look more professional. You can use a sanding block, but I prefer to just rub my hands over the glass for an even finish. Once you’re done with that, use #220 grit sandpaper to get all of those little scratches smoothed out. Then switch over to #150 grit sandpaper, which will give you that nice texture that makes it feel like real stone or marble (but don’t worry it won’t scratch your skin).

Benefits of Glass Block Divider Wall

  • Glass block dividers are very easy to build. They require little or no mortar and can be installed on concrete, wood, or any other substrate that you want to use.
  • They are easy to clean as well. You just need a soft cloth and some mild detergent to wash away any dirt or dust that might accumulate over time.
  • Glass block walls are strong and durable so they will last for many years without breaking down easily. If you have young children who like playing with toys, then you don’t have to worry about them accidentally breaking the glass blocks on your divider wall because they are made of hardened glass which means they cannot be scratched easily either.
  • If there’s one thing we love about this kind of partitioning system it would have to be its water resistance capabilities not only does this mean that water won’t leak through cracks in between each individual piece (thanks again); but also means that mold growth is less likely because moisture isn’t getting trapped inside any more than necessary either. To top things off; these types can also withstand heat up until 400°F making them perfect for kitchen tools.

Cost of Glass Block Divider Wall

The cost of a glass block divider wall will vary based on the size of the wall, and whether or not you hire someone to install it.

If you are doing the installation yourself, tools to get the job done include:

  • A miter saw
  • Tape measure and pencil (for measuring)
  • Level (for ensuring your cuts are straight)
  • Hand sander (if desired)

Maintenance tips for Glass Block Divider Wall

To ensure your glass block divider wall looks great, follow these tips:

  • Install a fan to keep the air circulating and dry out any moisture that may be trapped in between the glass blocks.
  • Clean your glass block divider wall regularly to remove dirt and dust from accumulating.
  • Use a sealant on all sides of the glass block to protect it from scratches or other damage caused by cleaning products or weathering over time.

This is how you make a glass block divider wall.

To get started, you will need:

  • Glass blocks of your choice. These can be purchased at a local building supply store and come in many different sizes and colors. If you are looking for something specific, they may even have those that are already cut into the traditional shapes (as seen above). As long as they are the same size and shape, they should work just fine.
  • Cement board – this is used to cover up the back of your glass block wall so that no one sees any messy wires or pipes when looking through it from behind. You will also want some mortar for attaching each piece on top of each other as well as a grout for filling in gaps between them (this creates an airtight seal). Finally, silicone caulk should be used around all edges where there aren’t any pieces overlapping this helps prevent water damage from getting inside cracks between blocks which could cause mold/mildew growth over time (which nobody wants).

Now let’s go ahead and install some cement board first by laying out strips across the flooring area where we’ll want them installed next step will be installing grout lines between every sixth row alongside edges where two separate sides join together

In Conclusion

After learning how to build a block divider wall, you can be sure that your home will look great. And as an added bonus, this project is relatively affordable and easy to install. So what are you waiting for? Get started today.
