How to Install Glass Block Windows?
- Step 1: Measure and Purchase Materials – The first step in installing glass block windows is to measure the area where the window will go. This will help you determine what size window you need. Once you have the measurements, buy the appropriate materials. You’ll need a few basic supplies, including glass blocks, mortar mix, grout, waterproofing membrane, and spacers (if needed).
- Step 2: Prepare the Opening – Before installing your window, prepare the opening where it will go by removing any existing frames or trim. Make sure to use caution when doing this as not to damage any other structure or wiring around the opening. Once all of the old materials have been removed thoroughly clean up the opening so that there is no dirt or debris left behind.
- Step 3: Install Spacers (If Needed) – If there is more than one layer of blocks being installed in your window frame then spacers should be used between each layer of blocks. Spacers help ensure each layer is properly aligned and spaced out from one another for a seamless finish. To attach them simply press them into place between each row of blocks while they are still dry before adding any mortar or grout.
- Step 4: Apply Mortar Mix & Lay Blocks – Once all of your spacers are in place spread some mortar mix along each side of the opening where your window will go. Begin laying blocks on top of this mortar mix making sure they are even with each other and level with one another as well as with the surrounding wall surface. As you lay blocks make sure they fit snugly against one another without any gaps or overhangs. Continue laying blocks until your desired number has been reached for your window frame size then let everything dry overnight before continuing on to Step 5 below.
- Step 5: Grout & Seal Window Frame – Once everything has dried overnight apply grout between each row of blocks using a trowel or putty knife ensuring that everything is filled completely with no gaps remaining between rows and corners of those rows are adequately sealed off from one another using caulk or silicone sealant if necessary at this point too. Finally add a waterproofing membrane overtop everything once finished grouting for added protection against moisture buildup inside your new glass block window frame and let dry before adding any trim pieces back onto exterior walls around it if desired!
