Ventilated constructions
There are two types of construction which can be used in the application of Rockpanel in ventilated constructions, as follows.
There are two possibilities for ventilated application of Rockpanel:
Open, ventilated construction | Closed, ventilated construction |
 |  |
| Legenda: | 1. 2. 3. 4. 5. | 8 mm Rockpanel board Weatherproof gasket Wooden frame Breathable membrane Wooden construction | 6. 7. 8. 9. 10. | Insulation (f.i. Rockwool) Stone or wooden construction Plasterboard Waterproof membrane Chair profile |
Open facade
The use of water-draining sections is avoided, and some of the rainwater run-off runs into the cavity behind the cladding.
Using open joints in a wooden construction, the structure behind the vertical batten should be protected by a breathable, water repellent and UV resistant membrane. The cavity behind the Rockpanel board and between the breathable membrane should be at least 20mm or the thickness of the battens (providing a cavity of 28 mm or 34mm).
With an aluminium construction Rockpanel recommends a cavity depth of at least 60mm. The insulation should meet the standard EN-13162, e.g. Rockwool with a density between 51 and 69 kg/m3.
Closed facade
The rainwater is drained off as much as possible on the outer side of the cladding. The recommended cavity depth for a ventilated cavity is at least 20mm, but in practice it is often the thickness of the timber battens (providing a cavity of 28 mm or 34 mm).
