I have just had a new rear timber fence installed. My side is the railing side and as I have a new swimming pool this new fence forms part of our pool safety barrier. As such I need to ensure the pool area of this new fence is non-climbable. I have already check with the inspector who is due to come and inspect early next week and they will not sign off on what many have suggested being a 60 degree wedge attached to the new railings. I am looking at battening out the rails and attaching fibre cement sheeting. Has anyone done this before? Not too sure on which way to hang the sheets either horizontal or vertical? Does it even matter??? Thanks
