 The custom built folding doors have been designed in the European Tradition of a full overlay of the sash into the jamb. This engineering principle provides the primary transfer of the positive wind pressure onto the contact area created between the merbau sash and the merbau jamb. The sash rails and styles of the folding door units have been developed to match all of the sashes of the production line, creating a unique solution in the industry by providing the same full over-lay principle as employed in our casement windows, French doors and Double-hung windows. |

 The construction and the joinery of the sashes and the jambs is executed in the dowel and coping tradition, providing the strongest connection based on Institut fuer Fenstertechnik in Rosenheim, Germany, the oldest European authority on the design and related research of the window and door manufacturing industry. |

| We use three dowels at each corner of the sash components. A standard folding door sash would engage 24 dowels in its construction. |

 Luxbaum Windows + Doors has pioneered the design of a full overlay sash with an integrated multi-point locking system in its design of the Folding doors. This concept eliminates the surface mounted bolts and creates a solution which is compatible with its entire line of windows and doors. A decorative handle is driving the locking mechanism along the edge of the sash, its header and its sill. This decision has been recognized as unique in the industry of hurricane tested Folding door systems. A truly residential solution creating the functionality of a French door and the flexibility of designing significant openings. |

 The design of the sash and its dual gasket system assure that no hardware components are exposed to the weather. The location of the primary gasket at the outside edge of the sash seals the airspace between the sash and the jamb, thereby protecting all other hardware components from corrosion. |

 All penetrations for fasteners are pre-drilled and coated to avoid bleeding cause by the high mineral content and pigments of the wood, unto adjoining surfaces during the installation. All fasteners are covered by a filler strip to trim out the installation.

A selection of muntins is available in fourteen different widths and designs, ranging from 13/16” to 2 13/16” in width.
Folding door units are completely pre-finished in the factory. The selection includes fourteen different stain colours and thousands of opaque finishes as per the available RAL colour-chart.

 Our success is based on the extraordinary qualities of the wood, called Merbau and the immaculate attention to the engineering and quality control during the fabrication of the units.
We have engineered a corner sash, employing a multi-point locking system, enabling the design of “disappearing corners”.
