Hello fiona and welcome to the forums..........On that size floor and timber with travertine, i would seriously think about an uncoupling membrane to stop any lateral stress cracks from expansion in the timber.........
I use ditra mat and it is spot on to use.......this can be bought from any CTD branch or if not available then give wetdecs a shout and he sells durabase uncoupling membrane....both will do the job and give a long last floor.......
