Specifications
MASTER ULTRA panel, manufactured in the shape of a flat panel produced by
moulding sintered polystyrene foam with improved thermal conductivity, 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); superficially provided with a robust
polystyrene film with a thickness of 0.15 mm, hot bonded into a single uniform, compact
structure, with surface marks for laying pipe and perimeter slots with complementary
interlocking allow a perfect coupling and alignment between the panels themselves
eliminating any possibility of formation of thermal bridges.
Use
The MASTER ULTRA panel consists of a moulded EPS sheet with bosses and covered
with a plastic protective film and is designed to offer high-performance underfloor
radiant systems.
• 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 thicknesses,
allows having the minimum possible insulation thicknesses 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.
