Technical Information
ECOFLOOR G is the ideal underfloor radiant system for heating and cooling systems for buildings.
The system consists of a rusticated insulating panel covered with a hard footstep-resistant black PS sheet that acts as a moisture barrier. The PEX AL PEX multilayer pipe with aluminum anti-oxygen barrier or the aluminum-free PE-RT pipe is laid on the panel, both very easy to handle during installation and in curves.
The installation of the system is simplified thanks to the insulating bosses, which with their pronounced profile allow an excellent locking of the pipe. The pipe is also raised from the insulating panel, so as to improve the heat exchange.
More powerful than ever
The ECOfloor radiant floor system has been optimized over the years. By selecting high quality materials we have improved the yield and resistance of the system.
The new ECOFLOOR G is formed by an insulating panel in graphite expanded polystyrene that has a greater insulating capacity of about 10% compared to traditional EPS panels.
Its robust HIPS protection layer makes it highly resistant to trampling. Calculate the price of the radiant system

Pipelines for maximum system safety
Piping is the fundamental component of a radiant surface heating system.
The pipe must meet numerous and stringent quality parameters in order to guarantee good performance and long life: high resistance values to stresses of different nature must be guaranteed for at least 50 years with excellent safety margins.
The use of PEX pipes AL PEX to, resistant to high temperatures (95 ° C), with oxygen barrier, ensure long-term plant without any need for maintenance.
The PE-RT tube also with oxygen barrier is very flexible, rests with extreme simplicity and has a low cost.
Distribution manifold
The modular collector, thermostatically controlled with display of flow rate, has been optimized for improve the thermal performance of radiant systems providing a low pressure loss.
The manifold is structured to be unaffected by sediment and from any type of corrosion.

- Resistance to chemicals
- Very low pressure drop
- Anti-condensation system
Quick couplers for pipe connection
The ends of the pipes are connected to the quick couplings and then connected to the manifold. Thanks to the quick couplings, installation is simple, quick and safe without the use of special equipment.
The modules are made of reinforced polyarylamide 50% of glass fiber, which confers mechanical properties similar to light alloys, but with much higher resistance to atmospheric agents.
Cassette collectors slim and stylish
The cassette for the 'accommodation of distribution manifolds Recessed is designed to easily position the collectors of radiant systems.
Manifold and box are arranged in the center of the building in order not to have too long circuits and to simplify the thermoregulation of the rooms, when crossed by many adductions.
Made of galvanized sheet metal, with tracks for fixing the manifolds, height-adjustable feet, frame and door with flat edge painted in white.
Banda perimeter to improve the thermal insulation
The perimeter band is positioned between the screed and the system structure.
This special fabric absorbs expansion and obtains good thermal insulation.
Made of closed-cell polyethylene, a lightweight and waterproof, complete with transparent strip, with a high resistance to chemical attack and the reactions of the alkaline cement products.
The additive for maximum performance
The screed in radiant systems in addition to the normal load distribution function, is the real heat carrier. The addition of ECOFLUID inside the compound improves the performance of thermal conductivity.
ECOFLUID is an aqueous solution to 40% active polymer capable of dispersing the granules of the additive cemento.Usando the advantages are evident as: the lower hygrometric shrinkage, the lower creep as well as a minor use of cement with consequent economic savings. E 'possible to modulate the action of the additive by varying the dosage.

Installation
Laying radiant floor system operates
The radiant floor system installation can begin when the building shell was completed and equipped with doors and windows to prevent air infiltration.
Before proceeding, ensure that they are checked the following conditions:
- interior plaster completed in all environments and beautifully finished until the raw slab;
- structural height verified for the realization of the heating floor;
- electrical and plumbing connections are completed, with tubes and pipes encased in a lighter background and level on which to proceed with the installation of the insulation boards;
- presence of niches in the walls for the collectors, holes in the walls and in the floor slabs for the passage of the connecting tubes in accordance with the wiring design.
The rough floors must be dry to avoid the withdrawal of the substrate, clear of dust and debris and present a good flatness with gradients within the tolerances as per DIN 18202.
The limit values of the height differences in mm depending on the distance of the measurement points are:

If the base is resting on the ground or in contact with a humid environment, before installing it should coat the substrate with a waterproof coating against rising damp as per DIN 18195.
Installing perimeter insulation tape
Before the isolation layer proceed to laying of the perimeter strip that acts as a joint between the screed and all building components such as walls which delimit, pillars, steps, etc.
Make sure that the inside plaster has been perfectly finished up to the raw slab, so that the adhesion of the tape to the vertical walls both total.
The tape must be laid starting from the raw slab to over the finished floor level and must be fixed, for example in frames of doors, pillars, posts etc., So as not to undergo displacements; to ensure the continuity perimeter insulation lay the tape overlapping the ends of at least 10 cm.
If there are more insulating layers, the perimeter strip can be laid starting from the penultimate layer. The part you just shave off the excess tape on the upper floor level, on completion of coating and in the case of textile and plastic surfaces must also wait for the curing time of the additive.
The transparent nylon has functional front flap to cover the peripheral edge of the insulating layer in order to protect it from the ingress of moisture from the screed. The correct installation is therefore expected that the insulating panel is matched to the edge insulation tape and covered by nylon strap: this last must then be secured with the pipe laying. It 'important that the nylon ribbon is not under tension but is approached to the surface of the panel.
- lay the first panel from one of the two corners of the bottom wall and proceed to form a line: if the remaining space is not sufficient for a whole panel, cut a panel to snap it into the available space;
- start the next row with the panel portion of the previous row (see figure 2.3);
- repeat the process row by row until completing the paneled surface;
- if for the last row is very little space cut the panels to the desired width.
The laying of the insulating layer must be from perimeter tape making sure that the edges in contact with the tape are covered by the strip of transparent nylon. Firmly join the panels with each other, taking advantage of the specific side to overlap MF, so as to avoid the formation of empty spaces between one element and another.
Before starting the installation you must choose a way of installation: it is advisable to lay the panels parallel to the outer wall or the wall opposite the door bottom. To minimize the waste of material it is recommended to proceed as follows:
Installation of the heating pipe
During the on-site transportation handle with care the tube and avoid exposure to direct sunlight; to facilitate the laying operations make use of a feed rotor, on which surround the tube, to be positioned from time to time in position with respect to the working environment. The type of development can be of the type spiral or serpentine: the first is to be preferred as it allows to obtain more homogeneous surface temperatures and to minimize the number of curves in 180 °; the circuit length and wheelbase to maintain the design data are to be followed.
The circuits may be placed under health such as bidets, bathtubs, toilets and showers (with the exception of the suspended type devices), and must maintain:
- 50 mm away from vertical structures;
- 200 mm away from chimneys, open fires, open pit boards or sides and lift trumpets;
- a radius of curvature not less than the minimum defined in the relevant product standards (see EN 1057: 1996, EN ISO 15874: 2001, EN ISO 15875: 2001, EN ISO 15876: 2001) A minimum indicative value is equal to 5 times the diameter of the tube.
The development of the radiant circuits depends upon the design requirements and can be of a serpentine or spiral type, as seen from the below pictures.
the heating tube mounting
The laying of the pipe is made easier and faster by the tube holder notches on the upper surface of the insulating panel. To start you should proceed starting from the perimeter zones and overlapping the tube to the strip transparent nylon to fix it permanently to the insulating layer. Subsequently developing the circuit according to design patterns and always ensure a good fixation without horizontal or vertical deviations with respect to the project locations.
