Standard these days (we're looking even if DH doesn't know! )
Tilt and turn are brilliant, and our last set in our old house was set so it tilted first - which meant that if you were little like me, it was a bit of a faff getting it to the turn position as it sort of default opened.
OK, I like these. We had them while I was growing up and again when we lived in Germany.
We are looking to get upvc (due to budget!) in our house but dh wants standard casement windows. He has conceeded it makes sense to have tilt and turn on the ground floor so we can have windows open in the living room when we are at the back of the house but wants casement windows upstairs.
If they look alike, do I let him have his way or should I fight for tilt and turn windows upstairs? I am not sure I feel as strongly about upstairs but like the safety aspect. DH thinks a casement window with child lock on would be better for our ds.
