Unlike bifold doors (where a flush track option is only suited to the most sheltered of locations), our sliding door tracks can be recessed into the floor to create a completely flush finish between inside and out without reducing the protection the doors offer from wind and rain. This is because the panels in the system sit down into the track rather than sitting upon it. The important thing to note is that a flush-finish needs to be planned in to your project from the start so that the track can be recessed to the right level to match the depth of your internal and external tiles or floorting material.
