Airtightness tape and steel beams

[Moggaman]

Hi. I think I have done the Airtightness tape well every where but I may have missed something. I have 3 I beams on the inner leaf above doors and windows. I have not put any Airtightness tape in these . Is that bad?

The vertical walls are a sand cement render finish and the reveals of each are plasterboard and skim.

attsched shows the way the beams were set up prior to plasterer arrived but he has his beads on now. 
thanks

Thanks for posting: my post does not answer yours above - but I doubt you have anything to worry about.

 

Could I ask you please what the  brand of fixings are for the fireboard fitted between the joist flanges?

I used a morter mix and filed the baps between the beam and the wall then airtight painted over.

 

I suspect you'll be fine though.
