Glass jalouise windows provide excellent ventilation, but they are susceptible to damage. Anyone with a screwdriver can repair these windows by sourcing the right parts.
Most jalouise windows were installed in homes more than 50 years ago, and many are in need of repair. The glass may have chipped, cracked or broken, and the metal hardware is susceptible to freezing up or wearing out.
Setscrews at each end hold the glass panes in place. These screws can be removed with a screwdriver and then the broken glass can be slid out. It's easiest to also remove a good glass piece and bring that to a glass company for them to get exact measurements for a replacement.
Jalousie window operators, strip hardware and linkage can be purchased online or at local hardware stores. These parts can be easily replaced using a screwdriver. Silicone lubricant is recommended to prevent corrosion and aide in window movement.
