junglejim Posted January 2 Share Posted January 2 Reading a lot about expansion gaps for cladding. We’re installing thermo ayous which has very small expansion figures so wondering if there’s any need for any gap at all? I’ve been allowing a few mil. each end 2mm ish between boards but quite fiddly lifting each board and where boards butt together along a long length it seems like a weak spot for water ingress. given that the boards are also fixed with 2 screws in each batten I’m struggling to see how the boards will expand… is anyone able to offer any technical insights into this? Thank you Link to comment Share on other sites More sharing options...
markocosic Posted January 3 Share Posted January 3 Boards will for sure move across the grain. Putting two screws in too far apart can result in the board splitting as the screws stay still and the wood moves. Keep them reasonably close together. What is the profile/layout being used? Most have provision for expansion. Link to comment Share on other sites More sharing options...
