Have any of you retrofitted double pane windows?

[Ronin]

I have now acquired a set of 6 double pane windows for my car with matching blueish tint for £180 delivered to Cardiff....

I will be doing a limo tint on the rears for sure and I wondering whether I should remove the glass and give it to the tinting company as just glass especially that (from my understanding) the guides that are in the glass will have to be removed to do the job properly (pic attached)

What do you people think?

Are there any 'while you're there' jobs to do in the doors while I have it all apart during the replacement? I already know I need to get loads and loads of door clips, but I'm also thinking of adding more sound proofing material inside just to make things that little bit better.
