You need 6mm thick Vysa-Pron thermal insulation sheets when installing Vysa-Film radiant floor heating elements.
If the heating is being installed in a conservatory, Vysal recommend 2 x 6mm layers of Vysa-Pron (12mm in total) to minimise downward heat losses. This will reduce energy consumption and improve response times.
In this application, no adhesive is needed to bond the Vysa-Pron to the sub-floor.
Vysa-Pron has other uses too. Use it as a stand-alone thermal insulation material to line walls. This has the added benefit of deadening sound too.
For model-makers Vysa-Pron is a very useful material in either 3mm or 6mm sheets. It is easily cut to shape using a modelling knife.
