Some materials do not seek attention, yet fully deserve it. Aluminium is one of them: lightweight, accurate, able to bring more light indoors and greater freedom to architectural design. Its strength lies in its discretion. Its quality lies in the way it is crafted.

Cocif brings to this field over eighty years of in-house production: a method that starts not from the product, but from the project. A window is not an object to be chosen at the end of construction, but an element that helps define the space, the light, and the elegance of an interior.

In recent years, aluminium has taken on an increasingly central role. The ability to reduce profiles, work with uniform surfaces, and achieve wide, lightweight openings makes it the ideal material for those seeking essential aesthetics and generous brightness.
Cocif’s in-house production allows all of this to be interpreted with precision:

non-standard sizes, material combinations, special construction-site requirements, colours conceived to complement the architecture. Not an adapted product, but a window or french door designed for a specific place.

When speaking of Cocif aluminium windows and french doors, the Infinity and Secret collections represent two different expressions of the same idea: letting light guide the project.

In both collections, aluminium becomes an architectural gesture, not a simple frame.

INFINITY focuses on slim profiles, wide glazed surfaces, and an aesthetic that reduces the visual impact of the structure to enhance the view. It works beautifully in contemporary spaces, penthouses overlooking the city, and homes where indoor and outdoor areas are meant to flow seamlessly.

SECRET enhances interiors with a concealed sash that offers clean lines, high performance, and excellent energy efficiency. A system designed for modern environments, low-energy homes, and projects requiring maximum visual purity and comfort.

Some places call for elegance, balance, and stylistic continuity. In historic centres, period houses, or buildings subject to conservation rules, windows and french doors must blend naturally into the existing architecture.

In both cases, aluminium provides everything needed today-comfort, insulation, reliability-through a language that respects its surroundings.

REFINED interprets this balance with classic lines and understated proportions while still offering the performance of a modern window or french door system.

TENDER, with an even more traditional design, sits perfectly within historic homes, family residences, and interiors that require a softer, more reassuring aesthetic.

Across the Cocif range, aluminium collections all move in the same direction: giving the project exactly what it needs, without complications.

Three distinct systems, one single goal: support the project with precise functionality and a design that stays light.

LIFTING is the effortless lift-and-slide system: easy to open, ideal for large glass surfaces, and always visually tidy.

VISION focuses on minimal, flush profiles for those who want maximum natural light and a clean architectural language, without compromising on high thermal performance.

CUBE, finally, is the most versatile solution: windows, french doors, concealed hardware, and an approach that adapts to different contexts without losing coherence.

Cocif’s true advantage is not only the product range, but the way of working.
Here every window and french door is built in-house: this means custom sizes, colours, details, openings, and special solutions without complex processes.

A real value for designers: fewer compromises, fewer constraints, and the possibility of obtaining exactly what the project requires.

The result is a system that does not impose a style, but expresses it.

Because windows and french doors should not be “the same for everyone”.
They should be the right ones for that specific context, at that precise point of the wall, with that light.
Because every project is unique.
