How to Install Frameless Glass Block Windows

Glass block windows are a great way to have the best of both worlds when it comes to windows - sun as well as privacy. They are great for bathrooms, as they let in natural light without allowing outside visitors or passerby's see inside the room, as the thick glass distorts images making them hard to view. The glass blocks are durable, but can be tricky to install. Read on for some tips on how to make a statement in your home and install these glamorous glass block windows in your home.

There are many benefits to using these glass block windows. Besides being durable, they are very pleasing to the eye and create a modern streamlined look. They create privacy, and prevent the room from becoming too warm.

Glass block windows can be obtained from the local home store at the cost of about nine dollars per glass block. Keep in mind the other supplies that are required for the installation such as mortar, and cedar shims to space the windows between each other. Other than that, glass block windows require minimal tools. Cement is the first choice for mortar, as it is going to be sturdier, and more waterproof than regular mortar.

The first step to installing glass block windows is to remove the old frame. This is not going to work with the new glass block windows, as they are frameless. A space of up to an inch is fine on each side because it can be filled with caulking, and caulking strips to prevent exposure to the elements. Using cement will ensure a waterproof finish that will last for years.

Spray the window sill with water and than put a ½ inch layer of the mortar before the first bricks are applied. Insert the cedar shims, so that the bricks are evenly spaced. These shims can be removed about two hours after the bricks have been set, and than immediately fill the holes with cement, using a trowel to make sure it is even.

After the first layer has been applied, start the second layer of the glass blocks, ensuring that the same layer (1/2 inch) of mortar is applied.

If any mortar has been applied to the glass, a damp cloth will remove the excess easily. Same goes with the silicone caulking, alcohol can be used to remove the excess, or should it adhere to the glass.

After the glass block windows have been installed be sure to secure them with a band, as if one accidentally bumps into the corner of the glass block wall, than they could easily fall.

After the glass bricks have been installed it is important that you caulk the top of the window with silicone caulking. This should be done about a day after the bricks have been installed for the best results. Do not try to caulk the entire top of the glass block window, caulk up to a maximum of ½ inch, than use a caulking rod to fill the void space.
