Can I ask which did you go for in the end? I have similar size house. One company recommending the highflow and another saying 2 units would be quieter/better

Cool, Thanks for that Adam. Looks like I am going like the attached detail now, sizes etc are not exact but I'm sure you get the gist of it. I'll probably use you rubber/neoprense idea around the bolts securing the U channel along with waterproof silicon etc maybe even a dpc coarse on top of ply under channel, can't hurt either, every layer helps

Magic water tight fixings? What are those then?

Hi guys, thanks for the replies. I only seen the response now. I'm still looking for a good thermal break free solution, unfortunately the concrete has been poured already as in the pic below. So as I see it there is a thermal cold bridge coming through on the concrete down into the hollocore ceiling as in the red line on the picture below. I am thinking on putting insulation on top of the parapet wall now and somehow fixing into the side where the green lines are in the drawing. I have contacted quite a few glass balustrade companies, my engineer etc, but none are quite giving me the answers I want to hear. In hindsight, I should have put insulation in the blue circle and put rebar up through and poured concrete on top, probably would of been the best solution Any suggestions thoughts on the best remedy?

Hi Adam2, I hope its ok to bring up an old post. I'm doing a self build with Amvic ICF, just about to finish roof and have a balustrade detail to figure out. Would you be able to share the detail you ended up going with in the end?
