We've got a new 3000 x 3000mm partition wall that we'd like to fix birch plywood panels to. The panel size would be 800 wide, 600 high and I'm trying to figure out how to best fix them to the stud work.
Here are some visual examples:
I've seen many visual examples on Pinterest but no explanation for how they've actually been achieved. Our builder's only suggestion has been to fix with countersunk screws and use woodfiller but he's agreed it would probably ruin the aesthetic.
I've looked at hidden fixings such as buttonfix: http://button-fix.com/ but they work out quite expensive as I'd presumably need 4 per panel for a secure fix. My only other thought is to use flush mirror fixings but not sure if that would be secure enough once we attach lights and sockets.
