Just a quick question, if your putting underfloor heating on a wooden floor do you overboard with ply before putting insulation boards down or can you just put insulation boards straight onto floorboards?

You will need to make sure you have a solid floor first... so prep is the key.. and then stick the boards down tot he floor boards and screw down as well... washers for insulation boards will be needed so the screws don't pull through..
Also make sure you use Alkaline resistant seam tape for the joints.
