To install glass block windows, create a frame, apply mortar to hold the blocks in place, and stack the glass blocks in the desired pattern. Use spacers to maintain even gaps between the blocks, and apply mortar between them. Once all blocks are in place, allow the mortar to set and dry before sealing the edges with caulk to ensure a secure, weatherproof installation.

Installing glass block windows requires stacking the blocks in mortar and using spacers for even gaps. Proper sealing with caulk ensures a weatherproof installation. Glass block windows add privacy and style, often used for bathrooms or basements.
