Ventilated constructions
There are two types of construction, which can be used in the application of Rockpanel in ventilated constructions:
Open, ventilated construction | Closed, ventilated construction |
 |  |
| 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).
