The custom built fixed 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 out-swing sash and the merbau jamb. This contact occurs at extreme wind load conditions, when the dual gaskets are fully compressed. The construction and assembly of the sash into the jamb copies the casement window assembly for a visual continuity.
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.
The number of dowels at the corners could amount to ten for the widest sash stile to rail connection. We use three dowels at each corner of the jamb. A standard double fixed window would engage 52 dowels in its construction.
Sash stiles and rails have been designed in various widths to offer the flexibility to architects and interior designers to design and proportion the sashes from a slim to a standard width, with any variables available in between. This decision has been recognized as unique in the industry of hurricane tested fixed doors. It truly offers the flexibility to custom design windows.
The design of the sash and its dual gasket system assure the same high performance of the casement windows. The location of the primary gasket at the outside edge of the sash seals the airspace between the sash and the jamb against moisture, airborne salt or sand.
All penetrations for fasteners are pre-drilled and coated to avoid bleeding caused 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.
Fixed doors 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.
