I bought a couple of these screens: Tuscan Path 1800 x 900mm Rust Leaf Screen Panel
I plan to install them secured along the bottom and up one side. Do they need to be secured with a frame around the top and other side, or will what I've got planned be secure enough? I notice that the picture on the product page shows them just secured at the bottom corners and one side, so it seems like it might be enough?
But if they need a frame, what size and type of timber would be sufficient? And what types of timber finish would work well with rusted metal effect of the screens?
