Make sure that the manufacturer of the render system use confirms how they want it done NOT the contractor. Weber for example can be very particular that these sort of details are built to their specif detailing, they will be issuing the warrant on the system so you must meet their specification.

Personally I'd raise this with SE, they should be specifying this detail for you not strangers from the internet! But yes, I've fixed a joist ledger board to a wall before with M12 studs (threaded bar) embedded in resin, its commonly used. However the frequency of the fixings and particular type of fixing should still be specified or at least ran by the SE for verification.

Morning all, I have been aware of TLA (thermal lightweight aggregate) as a construction product but more so used in large commercial projects but it now seems to be offered as a poured insulation subfloor to domestic project. https://www.energystoreltd.com/professional, this company seem to been a product wholesaler not a actual contractor. Just wondering if anyone has any experience of using this in a domestic project. In my experience fitting PIR floor insulation is a nightmare of a job for a whole range of reasons. Its a time consuming job, cutting the insulation around pipework to ensure a continuous fit of insulation all over the floor is near impossible and furthermore which contractors do you get to do it. A poured insulation seems to have many benefits, waste free, storage free, better performance. Is it not yet commonly used in domestic project due to cost or just hasn't been rolled out yet? Keen to hear your opinion!
