Which underay for laminate???

[sta99y666]

Hi all,

I have a new conservatory which has a concrete base, base is made up of hardcore, sand, DPM, concrete. On top of the concrete are batons and between batons is (jablite) EPS, rubbish I no but had no choice, anyway over the top of that is 18mm t&g chiboard. I have rad pipes under chipboard floor. As rad is not connected yet and it's winter the floor is very cold but level so which underlay would be best for warmth??

Many thanks.

Fibreboard style underlay is generally regarded as giving better feel and warmth compared to the foam roll style products.
