Ultra Slim

Ultra Slim

Low profile insulating panel in sintered expanded polystyrene (EPS), available in white and with improved thermal conductivity (graphite), to which a high impact laminated polystyrene film (HIPS) is coupled, obtained by means of a heat sealing process, available in different colors. The panel is also available without film. The octagonal studs’ arrangement allows the laying of pipes with a diameter of both 10 mm (in one direction) and 12 mm (in the other direction).

The heat-sealed film gives the system a sturdiness that can adequately resist the stresses caused by the trampling of the operators and the humidity of the screed during the construction phase; it also acts as a vapor barrier in the operating phase of the radiant system.

On the four sides of the panel there is a batten with overlapping and hooking of the perimeter edges in such a way as to allow adequate overlap and a solid connection between adjacent panels, ensuring an optimal seal during the installation of the panels and the casting of the screed.
