I wonder how much difference insulating that part of the stadium makes, given that it is effectively an outside wall on both sides? I guess the insulation is there to negate the wind-chill effect getting into the arena itself?
Probably a silly question but why do they need to put rockwool insulation in there?
is the stadium still having a grass roof to make it 'blend in' with the surroundings?
No, they ditched the Telletubby plans yonks ago.
was there a reason for it?
Yes, the 'bunds' at either end were going to be redundant - effectively just grass hills at either end to help the stadium blend in with the surrounding area. However, by the time planning permission for the stadium had been granted the building regulations had changed, requiring the stadium to have a lot more internal space. Therefore turning the two grass-covered bunds into a part of the stadium was the most simple solution as it allowed for the internal size of the stadium to be massively increased without changing the planned footprint.
I believe this was all covered by the 'housekeeping' planning ammendments a couple of years ago.
I'm sure if I'm wrong somebody will correct me.

Just a guess, would it be to help absorb some sound escaping from the stadium?
Pretty sure clippedgull is right. All of those panels are listed in the plans as an "acoustic screen". There was a link on here ages ago about the company that's doing it, I had a look at their website and there's loads of info about how the make sound reflect back off of walls. I'm sure it's part of the planning permission that noise doesn't escape the stadium
From that website it seems we will have the reflective barrier and not one which absorbs the noise, simply because the inner skin looks to be solid and not constructed with thousands of holes!
Obvious i know but at least the famous Amex roar will be contained inside the ground and not absorbed into the side walls
I'm liking those silver corrugated panels they're putting up in the 2nd pic. Very snazzy.
