Boards to use in the loft (Rothney AB52)

Good Afternoon! I am looking for boards to use in our loft. If anyone has boarding they are trying to get rid of, please let me know. Don't let it go to the tip :) Since most of the work I do is remote now I need some dedicated space so cleaning/clearing the garage but need somewhere to put it all. That is where the loft comes in :D We were very kindly gifted some boards last year but as they were outdoor decking boards we ended up using them for raised beds in the gardens.
