Exterior areas

Can I use the floor drains in exterior areas?

Show answer

Floor drains without odour traps can be used without restriction in exterior areas. If the floor drain has an odour trap, it must be removed for installation in exterior areas. Schlüter-Systems is the only manufacturer to offer an odour trap that is part of the grate-frame assembly and is therefore removable.

Floor coating

Can I use your drainage systems with floor coatings that have low assembly heights?

Show answer

Technically, a linear drainage system requires an assembly height of at least 5 mm. With our point drainages, the grate unit can be installed flush with the floor.
