It sits between 3 trades but you are the main contractor/client so you carry ultimate responsibility. You are also the one who is paying so if it goes wrong you will be the one who ultimately picks up the bill. I'm not sure what you are trying but failing to understand. Conflicting views on what... conflicting views on the requirements of the standards...that comes down to the level of expertise that individuals have. I personally gave a fair degree of experience with these screeds. I'm asked the same question a lot... the answer... see my previous post.Really helpful advice - thanks so much Ajax & Dave. One reason I'm tying to really understand this is because this sits between 3 trades: i) screed manufacturer/installer, ii) UFH designer/installer and iii) tiling/tile installer - and I'm getting conflicting views. So I'm back to basics - keep asking why!
I wonder if any prof tilers have actually experienced a screed cracking due to being heated up and then needing repair before tiling?
That your boiler is not available would not constitute a defence in any civil action you might take if the floor fails. You can just hire a temporary boiler... job done.
As I said you can do whatever you like. You may get lucky you may not... it's a lottery regardless but if you follow the rules it mitigates risk. We dont make recommendations for the sake of it.
