Hi

Perhaps someone might be able to assist me pls.

I will be putting in underfloor heating in a flat/apartment. The rubble has been cleared from between the joists. Insulation will be put in-between the joists. Then aluminium plates, resting on the joists, but sitting between the joists will be screwed in place. This is where the PEX pipes will lay for the hot water of the underfloor heating to run. Where the aluminium plates are screwed into the joists, an insulation tape (5mm) will be applied.

The questions is this please: What solid underlay should I use before putting in a 15mm engineered click system wood floor??

Being told not to use any form of wood such as ply. It has been suggested that I use a manmade synthetic material. A form of sheet rock so to speak. I was given the name of Kovar or Cabor (not sure of the spelling!!) that come in 18mm thickness, has a low tog and clicks into position. (MDF or sheet rock does not lock int position and thus the risk is that is spreads apart over time.) Apparently it allows the heat to rise and keeps the heat, so after the heating is shut off heat remains under the floor and therefore less energy is used. Has anyone heard of this please? Or a similar material that can be used please?

Many thanks indeed in advance.

Cheers, Frank
 
P5 T &G is fitted by glueing the T&G bit and is screwed down to all the joists , it does not drift apart, at least not if fitted properly.
