How to Replace Jalousie Window Glass
The jalousie window, also known as a crank window, is a feature in many older homes. The window has a few moving parts, usually attached around the crank.
If you have one of these windows, then you may sometimes suffer from broken glass, which can be repaired easily.
Rather than replacing the entire jalousie window, you will need to find a supplier of the glass, and then have some basic home improvement tools to hand.
Once you have removed the old window pane, fitting the new one will not be so difficult and will only take a few hours for you to have a completely restored window.
Step 1 - Take out the Old Glass
One of the first steps you need to complete is to remove the old glass from inside the window frame.
In order to do this properly, you should put on some gloves and safety glasses. Glass is dangerous and while you are removing it you are at risk from shards getting stuck in your fingers or flying up and getting into your eye.
How you remove the glass depends upon how it is broken.
A shattered glass may be in perfect position and you will need to tap it gently with the mallet to get it to fall out. Tap from the inside so the glass falls outwards, as you don't want your furniture covered in glass.
If it is broken and pieces have fallen out, then you should be able to knock out the small pieces and carry away the large pieces using your gloves.
Step 2 - Remove the Old Seal
Once all of the glass has been removed, take off the windowpane seal that was holding it into the frame.
You may need to unscrew part of the frame to get a good position, but once you pull it out you can grab hold of the seal and pull it gently away from the frame.
Step 3 - Install a New Seal
Take your replacement glass and fit it into the seal, holding the pieces into position while you apply a sealing glue around the edge.
Leave the window and seal to dry.
Step 4 - Install the Window
Once you have fitted the seal around the glass you are ready to install it. Take off the frame, or the actuator if there is one, and place it to one side.
Put the glass with the seal in, so it is firmly pressing against the frame. Add some more sealant glue to the base of the frame and allow that to dry. Once it has done so, you can refit the frame back into its space where the previous jalousie window had been, and screw it into position.
You may find you need to clean the new window once it has been fitted, to remove fingerprints and marks.
