18mm WBP ply minimum. Make sure the floor has no bounce, guess its too late to add any extra noggins to joists?

Dont use chip board

will heat come through 18mm ply and than heat tiles.

 

[HAB-1]

will heat come through ply and heat tiles

 

[nybor62]

yes it will

 

[Gazzer]

Just to say tiling direct to timber floors is never a good idea IMO especially heated floors.

^ Agree with the guys above.

Dont use chipboard for a few reasons.

just to clarify about this thread hab-1 rang me earlier , it seems the job had been done , timber floor over boarded with 9 mm cement board and tiled , the tiles did,nt get hot , he has ripped it all up and wants to start again

Think the heating needs to be on top of the cement sheet to work

 

[HAB-1]

which one will heat go through fast 18mm wdp or 18mm chipboard

 

[HAB-1]

which one will heat will go through fast 18mm wdp ply or 18mm chipboard

 

[HAB-1]

which one will heat will go through fast 18mm wdp plywood or 18mm chipboard

 

[jay]

Wouldn't recommend tiling directly on to either ,other opinions will differ

 

[HAB-1]

whats other option like.
