It's the window leaf itself that has bowed. Have attached couple of images that hopefully explain it better. It varies with each window but a lot of them have just warped all kinds of ways. The one below is probably a bit hard to see but has bowed in the middle.

Hey all, we have a mid 90's house with a couple of glass brick windows, one of which has started to seep with heavy rain causing the interior sill Gib to crumble. How should I tackle this as I can't see any obvious area where water may be getting in. Cheers

Hi, is there any minimum window clearance under NZ building standard? I would like to install a 1600x350x350mm wall mount side cabinet in my bathroom which will beside window. Is there any rule that can't be installed too close to the window due to the impact to the window structure?

Hi, I was hoping to do herringbone subway tile for splasback behind stove but I am also doing tile splashback behind my sink that has a window. Herringbone isn’t going to work there. Any suggestions on tile laying pattern that would look best for both? Considering stacked horizontal or vertical or traditional brick. Is there any way to still have herringbone by stove but dfferent by sink so it won’t look silly? Thanks! tile I am using - it is 75 x 300 layout
