   I would avoid anything organic. Water that makes its way under the LVT will not dry, and organic materials would just be mold food.

   Thanks Andy. I’ve noticed some underlays made for LVT are high compressive strength & have dimples which promote drying of any water which may get under. May try it , if I can find it. Supplies are so variable these days! Cheers

   That looks like a great product. I've never seen or used it. Have you installed that before Mr Greg_E ?

   I haven't used that specific product, but have used similar air gap products without the radiant barrier with good results. Over cold concrete I think the radiant barrier would be a good addition.
