    In light of the current Part L regs how do prefabricated concrete panels v conventional loadbearing cavity walls measure up against each other for medium rise buildings.

    Your thoughts are welcome! :)

    show me thermal bridge free detail where the concrete panels are fixed to priminary strcuture and then show me the cost of them. much better to go with a SIP panel and rain-screen cladding - also the expected new 2013/14 commercial TGD L regs will make prefab conc panels an expensive and difficult detailing option IMHO

    Agreed. I have never worked with concrete panels before but from initial research, the potential for thermal bridges and the problems associated with reducing them would seem to make the system infeasible.

    Could we be looking at the end of this form of construction? in it's current guise anyway...

    Thinking out loud now - perhaps if panels were delivered with EWI attached , rendered , edges projected only to be silicone sealed after , windows pre- installed ( all thermal bridges detailed away ) and with first fix m+e chases and conduits made/installed etc etc.

    In other words they have to do what high end timber frame companies have been doing for years and years now.
