Dimensional drawing
ACUSTIC ULTRA 30-2 panel, made of a rigid plastic sheet with bosses coupled
with a back panel in sintered expanded and elastic polystyrene, both with addition
of graphite, with a dynamic stiffness class SD20 (dynamic stiffness not exceeding
20 MN/m3) and compressibility class CP2, CE marking according to UNI EN 13163,
which ensures the mechanical, thermal and acoustic 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 ACUSTIC ULTRA 30-2 panel consists of a double-density moulded EPS sheet
with bosses and covered with a rigid plastic protective sheet and is designed to offer
high simplicity of installation of an underfloor radiant system combined with foot traffic
noise attenuation.
• The rigid sheet covering with shaped bosses on the perimeter allows an optimal fit
between panels, minimising the risk of formation of acoustic bridges;
• The use of a denser EPS in the upper part, that for filling the bosses, provides
panels with good compressive strength during installation of the system;
• The use of low-density EPS-T in the lower part of the panel allows obtaining panels
with foot traffic-noise attenuation properties;
• 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.
