Hi SuperJohnG,
Who/what did you use for your render board system? For our build I had originally decided on blocks and render but for some of the reasons you describe I am now considering a render board system. I have heard that some lenders are funny about "non-traditional" systems, did you have any issues? My build is in Scotland also (West Lothian) and I am currently looking for good local tradesmen.
Thanks in advance,
Mark
