Step-By-Step Guide On Installation
Window Measurement
Start by measuring the existing window opening or the area where the glass blocks window will be installed. Use a tape measure to record the width and height of the window opening. Measure the width from one inside edge to the other and the height from the bottom sill to the top edge. Do this at multiple points to account for any variations. If measurements differ, always use the smallest one. Subtract half an inch from both the height and width to allow room for adjustments during installation. Also, check the squareness of the opening by measuring diagonally in both directions.
Purchase Materials
With your measurements in hand, purchase the appropriate size of glass blocks windows. Remember, each glass block will have a specific size, and you will need to account for the size of the mortar joints, typically about a quarter of an inch. Apart from the glass blocks, you’ll also need to purchase other materials such as mortar mix, plastic spacers, caulk, and possibly a plastic mixing tub for the mortar. You may already own some of the necessary tools, but if not, now is the time to purchase or rent them.
Remove The Existing Window
Begin the actual installation process by carefully removing the existing window if there is one. Use a pry bar to gently remove the interior trim and any other hardware. Once the old window is free, remove it from the opening. Be sure to wear gloves and safety glasses during this step to protect yourself from potential injury. After the window is removed, clean the area thoroughly, removing any old caulk, paint, or other debris to ensure a clean, smooth surface for the new glass block window installation.
Prepare The Opening
Once the old window has been removed and the area is clean, it’s time to prepare the opening for your new glass block window. If necessary, repair any damage to the window frame to ensure a smooth and secure fit. To prepare for the mortar, dampen the window opening slightly. This will prevent the frame from absorbing the water in the mortar too quickly, which can weaken the bond. Also, apply a bed of mortar to the sill or bottom of the window opening, using your trowel to spread it evenly. This will form a secure base for your first row of glass blocks.
Install The Glass Blocks
Start installing the glass blocks from the bottom corner of the opening. Apply mortar on the side and bottom edges of each block, then place it firmly in the opening. Use plastic spacers between blocks to ensure consistent and accurate spacing. Check each block with a level as you go to ensure that they are straight and even. Continue this process until all the glass blocks are installed. You may need to use a rubber mallet to make slight adjustments to the blocks. Remember to clean off any excess mortar promptly with a damp sponge to avoid it hardening on the face of the blocks.
Seal And Finish
After all the blocks are installed and the mortar has dried (usually about 24 hours), it’s time to seal and finish the installation. Apply a bead of caulk around the perimeter of the window where it meets the window frame to create a weather-tight seal. Smooth the caulk with a caulk finishing tool or your finger. Allow the caulk to dry according to the manufacturer’s instructions. Finally, replace or install new interior trim if necessary. Congratulations, you have successfully installed your glass block window. Now you can enjoy the natural light, added privacy, and aesthetic appeal it provides!
