Not having lived with t&t windows I wonder do they mostly get used in the tilt mode.
Then threr is the planning of the window treatments as they must clear the windows for operation.
Next would be the cost.
Not a fan.
I have them in the bedrooms of my home and I absolutely love them. (the ones I have are french swings) I use them more in the fully open position than the tilted position. The fact is I really never use the tilted position.
As far as curtains, I have valances and roll up shades. Works well.
