Specifications
REFLEX ULTRA panel, made in the shape of a flat panel by coupling an aluminium
sheet with a panel in graphite sintered polystyrene foam, CE marking according to
UNI EN 13163 (for thicknesses equal to or exceeding 20mm), 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); the
surface sheet, in special aluminium alloy with a thickness of 0.3 mm to allow the best
heat diffusion, is provided with serigraphic guide to facilitate the operations of installa-
tion of the pipe; It is also equipped with two self-adhesive edges which allow a perfect
coupling and alignment between the panels themselves eliminating any possibility of
formation of thermal bridges.
Use
The REFLEX ULTRA panel consists of a flat sheet of EPS with graphite covered with
an aluminium sheet, designed to offer an underfloor radiant system with the maximum
performance.
• The aluminium covering provides the best heat distribution;
• 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 flat shape provides the pipe of the system the best contact with the screed and
thus the highest thermal output.
