Dimensional drawing
SIMPLE ULTRA panel, made of a rigid plastic sheet with bosses coupled with a panel
in graphite sintered polystyrene foam, CE marking according to UNI EN 13163, which
ensures the mechanical and thermal resistance characteristics, free of recycled and
Freon gas, flame propagation delay (Euroclass E reaction to fire according to UNI
EN 13501-1); suitable for installation centre distances that are multiple of 50 mm;
equipped with suitably dimensioned perimeter bosses to allow a rigid connection by
overlapping the panel’s sides, ensuring a perfect coupling and alignment between the
panels themselves and eliminating any possibility of formation of thermal bridges.
Use
The SIMPLE ULTRA panel consists of a moulded EPS sheet with bosses and covered
with a rigid plastic protective film and is designed to offer maximum simplicity of
installation of an underfloor radiant system.
• The rigid sheet covering allows a high degree of compressive strength;
• The use of an EPS sheet allows obtaining panels with the minimum thermal
conductivity possible for this material;
• The minimum conductivity, in combination with a production with exact thickness,
allows having the minimum possible insulation thickness while meeting the thermal
resistance requirements of the standard;
• The bosses, shaped with appropriate finger grip clips, allow an easy insertion of the
pipe of the system while ensuring it is held in position.
