Perfect for sitting in between Joisted or Batten floor constructions. This product can sit on top of Rockwool or Polystyrene sheet insulation.

This system offers a great solution for 1st floor installations and the Aluminium diffusion trays are superb for even heat distribution whilst the Rockwool or Polystyrene sheets counteract and potential for downward heat loss. 

Once installed the system is pressure tested, the system must hold pressure for at least 24 hours prior to installation of 18mm engineered floor boards or tile backer boards.
