Not strictly correct ..And this is what you're aiming for...

Care to elaborate? The example given was approved by Velux. We can only guess regarding the elements we can't see, but it looks like a decent install to me.Not strictly correct ..
It won't be approved by velux, they just haven't seen it.The example given was approved by Velux.
The only thing I can see is the header tiles are a wee bit close to the unit.Care to elaborate? The example given was approved by Velux. We can only guess regarding the elements we can't see, but it looks like a decent install to me.
But if tiles are 330mm and if min head lap is 75mm them max length of tile showing without one above it showing through is 255 or at max head lap of 120mm max length is 210mm or have I misunderstood what you are statingWhen installed correctly, there should be approximately 250-280mm of tile showing under the bottom apron.
Definitely not 50-60mm
It's a poor example . Cut course under the window for one ..That's a great example.
