This is an upgrade? It should be🤬 standard, that's why I assumed it was foam injection for the Energeto 8000

Yes, just trim it back, will make your life easier. Without knowing the product supplied, I can't really say what the values are as I would be guessing but in principle, if triple and insulated frame (foam injected into the frame), you're probably looking at the Energeto 8000.

Foam just needs tidied up and then plaster, also aluplast, well done. 4000, 8000 or Energeto? Did you purchase from a UK supplier?

You should be able to take measurements internally/externally in the same fashion. That diagram is perfect. The internal measurements compared to external will be different and depends on finishes, they could be the same but if brick to brick externally, then I’d expect internal to be slightly smaller as the window measurement will be reduced by the plasterboard (if it is not sitting behind the ingo/check reveal). I doubt it is a check reveal if you’re in England.

Without seeing the outside, it’s impossible to say but do you mean survey as in inspect?

The best person to speak with is @fatgus, he was looking at them recently. I’ll drop you a message.

They don’t have a clue because they don’t check the details or enquire where the reed contacts come out of the frame. Most don’t even know where the reed contacts are located.

@raja22835 drop me a message, I may be able assist.

It's basically UK standard v's European DIN standard. To confuse matters, European entrance doors are usually viewed from the external side.

Birds, 9x10 it is birds, they love the mastic for some reason. I've had to repair mastic on numerous windows and rubber seals over the years.

Correct, that's the same for the external canopy.

Those fixings would be ideal in this scenario for you.

Have you considered just using glazing beads and hidden fixings though the bead and finish with glazing tape and silicone bead around the glass? The beads are generally what hold the glass in please.

Either agrees or took the lesser of two evils, I'll go with he just didn't want to fight it further. Either with legal advise or not. I'd suggest he has been informed that he'd lose and incur the legal costs as well to defend it further and would end up costing him a lot more, an excellent result for you. Unfortunate it has had to go the way it has.

I would say that is the intended design.
