Hi Everyone,
I'm sure this is relatively straightforward for someone out there. Planning on replacing existing suspended timber floor with deeper joists and insulating. I've looked at joist spans/spacing etc and understand all this but I can't find anywhere about how you practically layout and position the joists - I've got a 3mx3m room, at 400 centres I'm at 7 joists with ~100mm left at either side of the room. Is it ok to leave this 100mm unsupported finish floor at either side, or do you put another joist at the ends effectively with like a 100mm centre? Also, what is the best approach for laying out, is it start with a joist in the centre and work out, or basically work from the room width, find how many joists at 400 centres and see what's left when you get to the wall?
Thanks in advance!
