E-DRY Evo is an underfloor heating and cooling system without screed, characterised by its low weight and its low construction height (34 mm). The system is suitable for new energy-efficient constructions as well as for modernising old buildings. The core of the system consists in the polystyrene panel with an applied heat emitting aluminium foil, 16-mm Comfort multi-layer pipe and the calcium silicate board with tongue and groove profile.
