Prepare a strong support for the cladding and an air space
Battens and counterbattens
For vertical cladding, a system of crossbattens is required : a first set of vertical battens and a second set of horizontal battens at the same pitch.
For horizontal cladding, a network of vertical battens is required.
Ensure there is an air space
It is essential to allow air to circulate vertically behind the cladding, between the battens. The battens must not prevent air circulation. There must be an air space of 22mm between the cladding and the coating (film, insulation material, wall).
For this reason, battens that are at least 22mm thick allow good air circulation, when installed as cross-battens. The tops and bottoms of the air spaces must allow air to escape towards the outside and not toward the inside of the building.
Épaisseur et entraxe des tasseauxThickness and pitch of the battens
The gap between the battens will vary between 40cm and 60cm. We advise you to use Category 3 or 4 battens.
For a 50cm pitch, the thickness of the battens will be at least 27 x44mm.
For a 40cm pitch, the thickness of the battens will be at least 22 x 45mm.
Anti-rodent grid/ Distance from the ground
We recommend using an anti-rodent grid to prevent birds and rodents from getting between the cladding and the rain-proofing.
The distance from the ground of the coating is recommended ny DTU 412 to be 20cm. At the foot of the wall, the soil will remain bare or will be covered by gravel in order to prevent splashing.
