There are two types of construction, which can be used in the application of ROCKPANEL in ventilated constructions:
Open, ventilated construction
Closed, ventilated construction
|8 mm ROCKPANEL board|
|Insulation (f.i. ROCKWOOL)|
Stone or wooden construction
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 28 mm or the thickness of the battens (providing a cavity of 28 mm or 34 mm).
With an aluminium construction ROCKPANEL recommends a cavity depth of at least 40mm. The insulation should meet the standard EN-13162 (density 30 - 70 kg/m3), e.g. ROCKWOOL with a density between 51 and 69 kg/m3.
The rainwater is drained off as much as possible on the outer side of the cladding. The cavity depth for a ventilated cavity is at least 28 mm, in practice it is often the thickness of the timber battens (providing a cavity of 28 mm or 34 mm).
