Technical Information
Ceiling and wall heating and cooling
Ecowall Dry is the radiant system pre-assembled in plasterboard for heating and cooling wall and ceiling.
A modular system ready for installation, it is ideal for winter heating and summer environments; ECOWALL Dry allows any type of application, from the household sector to the service sector, from new installations to renovations.
The modularity of the system allows perfect adaptation to the sizes, both in wall applications as those on the ceiling, without compromising on architectural type.
Heating and cooling in the panel
The system ecowall DRY consists of plasterboard panels with different geometries and maximum modularity: 4 different formats allow maximum adaptability to different architectural requirements.
To this is added the system of integrated adductions that, in addition to speeding the laying operations, allows to reach a higher percentage of coverage in terms of the active surface.

High yields with great energy efficiency
The radiant coils ecowall DRY are housed in the drywall and not in the insulating layer: the maximum contact factor between drywall and tube increases by almost 10% of the system yield.
The active sheet is coupled to an insulating layer in high density EPS of 40 mm: the adductions pass directly inside. At the connection points, the insulation is not interrupted but a 1 cm thick plate remains behind the pipes: it is not necessary to further insulate the supply pipes. The low temperature power supply of the panels and the maximum insulation make ECOwall DRY ideal for high energy efficiency applications.
Low thermal inertia with the plant in plasterboard
Ecowall DRY is faster in full operation and in response to the regulation: the reduced thickness of the active layer, only 15 mm plasterboard sheet, gives the system a very low thermal inertia.
Comparing the thermal capacity per unit area of the plasterboard plate of Ecowall DRY with that of a traditional screed with 65 mm thick, it is seen that Ecowall DRY is approximately 10 times faster than a radiating system under the floor.
- Full operation in less than 1 now
- Quick response to regulation systems

Installation
Installation of radiant panels for heating and cooling on the ceiling
Upon receipt of the material in the pipeline be put into storage in a dry place away from sunlight and bad weather. The panels ecowall Dry should be moved carefully lifting them from the long side without sharp falls.
How to install
The application of radiant ecowall DRY can take place ceiling e wall realizing respectively false walls and ceilings radiant.
In both cases, for the laying of the radiant panels it is required the realization of a metallic frame. The fixing of the modules to galvanized profiles constituting the property via a system of screws.
For proper installation it is good to take the following precautions:
- Use screws with a minimum length of 5,5 cm;
- Adopt distance between screws ca. 20 cm;
- Position the screws in the middle between the tracks of the tube drawn on the panel.
Installing radiant ceiling panels
The radiant ceiling ecowall DRY can be of two types:
- In compliance with single warping;
- Suspension with double frame.
In both cases it is necessary to provide for the realization of a bearing structure.
The active surface must be developed leaving a distance of about 3-5 mm from the perimeter walls: an 'alternative may be to use of the spacers.
As for the normal controsofitti is good expansion joints to be applied each 15 sqm.
In the case of ceiling grip, galvanized profiles are applied directly to the ceiling to form un'orditura simple.
With this mode of installation, not being available the technical space above the panels, it must be ensured bands for the passage of the connecting pipes of the main circuit to the collector.
The realization of the suspended ceiling, instead, requires the realization of a double warping support pendinata and float to which attach the prefabricated panels. The distance of the hooks of hangers should be about 90 cm as seen in the following images.
In all cases the closure of the false ceiling panels with non-active can only take place after completing the hydraulic connection and scoring the leak test of the entire plant.

Installing radiant plasterboard wall
The radiant panels ecowall DRY can also be applied to the wall with single metal frame, similar to ceiling applications.
Realizing un'orditura single metal profiles are applied directly to the wall with a distance of laying 50-60 cm depending on the direction of routing than radiant panels: follow the requirements of paragraph 3.2.1.
The fixing is carried through the system of screws previously illustrated. Tamponade, shaving and grouting can be done after the testing of the system.
The mounting requires adherence to predict their rights of way for the passage of the backbones of circuits leading to the collector. The closure of the ceiling panels can not only be active after completing the hydraulic connection and performing the leak test of the entire system.

Leak test plant Gypsum Chilled
Finished with the installation of radiant panels and connecting of simple circuits to form complex circuits, you must make the leak test of the same.
The tightness test is carried out by the flushing take place at a pressure equal to about 4 bar for a minimum time of 24 hours: the pressure drop should be less than 0,3 bar.
When there is a risk of frost, it must take appropriate steps such as conditioning of the building or the use of anti-freeze. Quality of the filling liquid, temperature and dilatation of the pipe may drop off the pressure beyond this value: in this case to complete the test is the need to refilling of the system.
If the normal operation of the plant does not require additional protection antifreeze, the antifreeze must be drained and the plant must be flushed with at least 3 water changes. It should also carefully avoid fouling inside of the hydraulic lines and radiant.
Closing of the radiating surface
Once the hydraulic connection and the tightness test have been completed, the radiant surface must be closed with non-active infill panels. The closing of the niches in which the fittings are housed, once the insulating shell has been installed, must be carried out with the appropriate plasterboard plugs.
Expansion joints must be provided as indicated in use for suspended ceilings. Once the installation is complete and the radiating surface, you can proceed to grouting and final smoothing.
Before proceeding to the final finish of the wall with mural painting shall be drawn from a fund covering white to even out the surface and regulate the absorption of the paint itself.
It is always recommended to follow the manufacturer's instructions for each material used and to perform the trim conditions of controlled humidity and a temperature of at least 15 ° C.
Start-up radiant ceiling system
Before painting walls you can proceed with the start of the plant radiant wall / ceiling, provided that the building envelope has been completed with the installation of doors and windows.
The starting takes place at an initial temperature of 25 ° C, which is brought to the design temperature according to the following scale:
