Moggaman Posted February 19, 2022 Share Posted February 19, 2022 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 Link to comment Share on other sites More sharing options...

ToughButterCup Posted February 19, 2022 Share Posted February 19, 2022 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? Link to comment Share on other sites More sharing options...

Iceverge Posted March 6, 2022 Share Posted March 6, 2022 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. Link to comment Share on other sites More sharing options...
