1200x1200 awning windows - fully reversible?

[hauntedicecreamvan]

I'm looking to replace all my windows. Most windows are a mix of either 2400x1200 or 1200x1200 squares. Currently they are mostly split with a vertical mullion into 2x 600x1200 or side casements with a large fixed central pane, but the design of the property looks so much better with the original simple square windows.

 

I understand that 1200x1200 is right on the limit of a standard uPVC awning window when using 4-20-4 glazing, and exceeds it for 6-18-4. Anecdotally I've seen large uPVC awning windows fitted to properties and they felt so flimsy and were barely usable after a few years, whereas my smaller 600x1200 openers are fine after 30-odd years.

 

I can't fit tilt and turn due to obstructions in the window reveals internally.

 

I see that fully reversible systems like Rehau Total70R allow up to 1400x1400 sashes. They have a "flush casement" appearance when closed, and some systems have a brush pile to cover the hinge slot. I don't need any of the reversible features, although even on ground floor I suppose it could make cleaning easier since you're standing higher inside.

 

Does anyone here have these windows? Any disadvantages to be aware of? I guess they require more care with squaring the frame and toe-and-heeling glass during installation.

My windows by norrsken spin right around I’m not sure if that’s exactly what you want, but I’ve been nothing but impressed with them since fitting 4 years ago.
