Just finished installing drainage and water pipes in the floor structure (upstairs) for the new bathroom. Planning to have waterborne underfloor heating, so here's the question:
I'm going to lay chipboard, frame for the underfloor heating pipe, metal plate, pipe, plaster, etc...
Should I use any special chipboard or can I use the same as the rest of the upstairs??
Want to do it right from the start :S
Thanks in advance for the answer
