To be fair, our original plans were for membrane and cladding but we started looking at stone slips after seeing another self build and then porcelain tiles. Our local Durisol rep put us in touch with Steve Keitley (PRB Systems) who had previously worked for Parex, the only render with a BBS certificate for use on Durisol. He was very confident in his suggested combination of products but the BCO would not accept it without certification. Yes they are regarding Durisol as a solid wall, which it is. JohnMo what was used to stick your stone slips? PeterW thanks for the info , I’ll check it out.

Unfortunately building control take no notice of the weather , just data and certificates.

Hi. I’m new to the forum but close to the end of my self build. I’m having a few misgivings about building with Durisol as building control are being very restrictive in what finishes they will allow. Even with the only certificated render, Parex, they will only accept it if I can show that the local wind driven rain index is less than 75. The only data I can find states that the whole of Cornwall is over 100. Does anyone have experience of similar issues? John
