Installation of BG-FA facade channels with a sealing below 150 mm

With the insertion of the BG-FA facade channels, water escape behind the seal is avoided. When a drain is installed on the threshold of a door or balcony (or on upper floors), it is possible to lower the height of the step from the recommended 150mm to 50mm. This enables wheel chair patients an easier exit and entry.
Adherence to the height of the sealing is applicable for the entire area of the façade.

Installation of the BG-FA facade channels on a roof terrace

The BG-FA facade channel with a connecting channel can even be employed in a construction of insignificant height, and it is advisable to use it where there is a longer distance to the next drain pipe.  (Cover element).

-

Installation of the BG-FA facade channels for areas in close proximity to earth

Accrued rain water is drained off to seep into the subsoil by BG-FA facade channels with a one sided perforation, and laid in a gravel bed or constant concrete.
BG-FA closed facade channels are suitable for controlled drainage of rainfall water, and can be connected to the surface drainage system.
