We are converting 3/4 of our garage into a bedroom/clinic for my wife.
The Garage already has a concrete floor with DPM. The plan is to install a 2nd DPM over the concrete then make a false floor with 125mm joists, followed by 18mm interlocking chipboard floor (75mm urethane Insulation underneath) and my Wife wants a tiled floor.
Would I be better using something other than 18mm chipboard if I want to tile on top afterwards?
