Design study and costing · 2026

Study of 13 bespoke aluminium windows and doors in Opio.

The Opio file brings together six sliding doors, five fixed glazed units and two concealed-sash French doors. A fine-textured RAL 2100 finish creates a consistent appearance, while thresholds and cover trims are requested individually by item.

The dimensions below come from the October 2026 pricing request and the supplier’s response. They describe configurations studied before technical approval and the start of manufacturing.

The stakes of the study

What this file helps to prepare.

Coordinate thirteen openings with different functions, a shared finish and thresholds adapted to each passage.

A consistent façade, different uses

The six sliding doors, five fixed units and two French doors share a fine-textured RAL 2100 finish. For your project, a consistent finish can be maintained while distinguishing daylight, ventilation and access.

Finished floor levels planned for each opening

The requested recessed and accessible thresholds require recesses and connections to be checked individually. The window and door schedule provides the basis for this coordination.

Hardware assigned to the correct item

Three-point locks and cover trims for the French doors are specified alongside their dimensions. This detail clarifies both the quote and preparation of the order.

01 · From choice to detail

Compose fixed and opening sections.

The five fixed units complement six sliding doors and two French doors. The study separates their functions: daylight, ventilation and access. Integrated cover trims are requested for the fixed units, while French doors have their own hardware.

02 · From choice to detail

Prepare different threshold levels.

Four sliding doors are requested with recessed thresholds. Another sliding door and both French doors are requested with accessible low thresholds. The file therefore plans recesses according to each opening, with drainage and weather-sealing connections to be defined during the installation assessment.

03 · From choice to detail

Detail the French doors.

Both French doors are specified with concealed sashes, three-point locking and integrated 20 mm cover trims. These features must be checked against dimensions, the system and opening direction before manufacturing begins.

From the study to our Valbonne workshop

A series of windows and doors, each item tracked.

For an installation comparable to Opio, every frame retains its item reference while lengths and hardware are prepared. FOM saw cutting, profile preparation and assembly all follow the same project file. For the client, this tracking connects approved choices with the windows and doors planned for each room.
