Timber Screw Joint
Battens should be a minimum of 20mm thickness to provide adequate ventilation. Batten width should be minimum 100mm for supporting battens, and 45mm for central battens. Joint gaps between boards should be a minimum of 8mm and a maximum of 16mm. When using timber battens, always use Cembrit EPDM with profiled ribs.
Timber Screw Detail
Cembrit recommends using an EPDM of the same width as the selected batten. Cembrit facade boards can also be installed on horizontal battens. When using horizontal substructures, there must be a minimum 20mm ventilated area behind the horizontal supporting battens.
Aluminium support system Mounting 8mm Cembrit facade boards on aluminium Max. support distances: 629mm o.c. Max. rivet centres: 600mm Max wind load: Please refer to the wind load table for the correct distances for substructure and rivets. The following rivet types can be used for this construction: Cembrit Rivets Aluminium RIV-A 4.0x20mm
Aluminum L Profile Detail
Cembrit facade boards can also be installed on horizontal aluminium systems. When using a horizontal support system, there must be a minimum of 20mm ventilated vertical area between the profiles and the supporting wall or insulation.
Aluminum T Profile Joint
Edge Distances There should be a minimum of 20mm from the reverse of the facade board to the front face of the insulation to provide adequate ventilation. T profiles behind joints should be min 100mm width, and the L profiles should be min 40mm width. Joint gaps between boards should be min 8mm and max 16mm. The use of flat EPDM on aluminium profiles is optional, but from an aesthetic point of view, it may be advantageous to use it as the aluminium profiles will otherwise be visible through the joints. Alternatively, you can use black UV tape or painted aluminium profiles.
To ensure the optimum, long term performance and aesthetic characteristics for Cembrit facade boards it is vital to ensure that the support system substructure is absolutely straight, horizontally and vertically. In order to ensure this, please follow the guidelines below. Straightness of substructure The horizontal tolerance is +/- 3.0mm measured over a distance of 2 meters The vertical tolerance is +/- 0.5mm over 600mm measured over a distance of 2 meters.
Top Hat Centers
Edge Distances There should be a minimum of 20mm from the reverse of the facade board to the front face of the Windstopper or insulation to provide adequate ventilation. The profiles behind joints should be min 100mm width, and the middle profiles should be min 40mm width. Joint gaps between boards should be min 8mm and max 16mm. Always use flat EPTL/EPDM on steel profiles as it will provide adequate protection of the boards from moisture movements. From an aesthetic point of view, including the EPTL/EPDM will also make the steel profiles less visible through the joints.
Top Hat Centers
Cembrit facade boards can also be installed on horizontal steel profile systems. When using a horizontal Cembrit VFL profile, the profiles can be mounted directly on the wall since it is perforated and the air can move freely. If using other horizontal systems, a minimum of 20mm ventilated vertical area between the profiles and the supporting wall or insulation must be ensured.
