Indoor Cost Guides      Window Installations      Glass Block Window Installation Costs

Glass block windows are a popular option, and they can be used on a range of different windows around the home. They are often used as a means to provide more privacy to certain areas of the home. These types of windows will still allow in light, but people will not have to worry about anyone being able to see inside. In addition, these glass block windows can work well to provide additional insulation. They are common in bathrooms, but they could be used for other areas, as well.

The glass blocks for windows are available in a range of sizes, as well as various colors. In addition to being used for windows leading to the outside of the home, they could also be used within the home in a wealth of interesting ways.

DIY considerations

  • Take care when removing the old window, so you do not break the glass or damage the frame.
  • Once the tracking is installed, you can start to place the glass blocks into the window, starting in a bottom corner and completing one row at a time. The final glass block should go into the space where the tracking was cut out.
  • Seal the blocks with silicone.
