Hi all, I purchased a sliding door system https://www.screwfix.com/p/henderson-marathon-j3-1-door-sliding-track-system-silver-1473mm/2699j and I am wondering what is the best door for me to get to use with it? can I just go to B&Q and get a solid pine door and just rebate the top of the door? Any advice I would really appreciate! Thank you.
