Valuable advantages>> competitiveness: the “smart solution” combines economical advantages with the usual
technical performances of pre-insulated aluminium ducts;
>> fast to assemble: pre-cut panels are supplied inside a box, few easy and fast moves are
enough to complete the whole operation;
>> technical quality: the product fully complies with the requirements of low pressure systems.
The specific panel with a 12 mm thickness grants a thermal insulation comparable to a 20
mm thick rubber mattress;
>> off-cuts reduction: the pre-cut solution optimizes the use of the material itself by reducing
the off-cuts.
The new smart8 solution also reconfirms and guarantees all the technical characteristics
which, for nearly 20 years, have been appreciated in all the rectangular versions (indoor and
outdoor) of P3ductal system, such as:
>> total safety in case of fire: Class B-s2,d0 according to the European UNI EN 13501-1 2005;
>> highest security in case of earthquake: due to the high rigidity and lightness of materials;
>> very high hygiene and quality of the air: thanks to the use of aluminium for the internal
surface of ducts
>> complete respect of the environment: our smart8 panels are made using the exclusive
“Hydrotec” technology, which utilizes only water for the expansion of the polyurethane insulation.
This solution avoids the use of the undesired greenhouse effect gases (CFC, HCFC, HFC, HC).
>> very good thermal insulation: λi=0,022 W/(m °C) at 10 °C
>> very low friction losses: thanks to the fact that the internal surfaces of duct have reduced
roughness.
>> extraordinary air seal: our special “labyrinth” bayonet, thanks to its particular shape, cre-
ates a true labyrinth which drastically reduces the air leaks. Thanks to the bayonet and the
available frames a very good air seal is guaranteed.
Where to use P3ductal smart8
The new smart8 solution for octagonal ducts is efficient, economical and ideal for those
visible systems which require both high insulation and aesthetic properties.
• pressures up to 300 Pa
• available sizes are from 150 to 400 mm (with a 50 mm interval)

The real secret of the smart8 solution is it’s fast and easy assembly.
The philosophy is simple: starting from a straight duct, which can quickly
be assembled thanks to the special kit, you can obtain all fittings (bends,
reductions, off-sets, etc.) necessary to construct a complete duct system
for any requirement.
The steps to follow are few and fast:
1. using the pre-cut panels, 12 mm thick, you assemble the straight ducts,
folding them over and closing with the “labyrinth” bayonet (panels and
bayonets are provided together in a box kit form);
2. with a specific straight frame it is possible to unite the single pieces of
duct, in order to obtain any length of straight duct.
3. in order to make the fittings you start from the straight duct and with a
series of transversal cuts you obtain the single components that, once
twisted and re-united, generate the fittings.
4. the various fitting’s components are united using angled frames.
the special “labyrinth” bayonetcreates a real labyrinth which drastically reduces the air leaks
Construction simplicity: the winning formula
> Applying the frame[1-2] Insert the frame by applying a normal pressure [3] Spread a layer of glue on the inside of the frame in order to prepare the
joining of the next section of duct.

> Joining the straight ducts and applying the clips[1] Block into the frame the end of the next section of duct. [2] Apply the clips, [3] on more than one side if needed, in order to
guarantee the air seal of the join even during the drying period of the glue.

> Duct closing with the labyrinth bayonet[1] Fold the panel in correspondence to the pre-made cuts, in order to obtain an octagonal duct. [2] In order to easily maintain
the shape, fix one end of the duct with a frame. [3] Turn the duct around and [4] insert the special bayonet in the joining slot,
present on the panel, [5] and help yourself if necessary with a rubber hammer.
