Growing without moving

Creating space differently

Expanding your home is often simpler - and smarter - than changing your address. 
A well-thought-out extension saves square meters, improves daily comfort and adds lasting value to your heritage.

Thanks to aluminum, you benefit from a modern, lightweight solution that's perfectly adaptable to existing structures. Installux systems offer total architectural freedom, without compromising on insulation or aesthetics.

Expand without betraying the existing

Each extension project must respect the soul of your home.
Proportions, volumes, architectural lines, finishes: everything counts.

Thanks to the slimness of its profiles and its modularity, aluminum integrates just as well with a contemporary house as with a more traditional building.

  • Fine profiles to let in maximum light
  • More than 400 shades available at no extra cost
  • Customized design, designed for your lifestyle
  • Harmonious integration with existing structures

Solutions for every project

What type of extension should you choose?

Aluminum conservatory

A true living space, the aluminum conservatory brings light and comfort all year round. 
Installux solutions combine high-performance glazing, thermal insulation and comfort options for use in all seasons.

Stores, roller shutters, integrated lighting or home automation management: every detail is thought out for your well-being.

The pergola

Ideal for extending the house outwards, the pergola creates a semi-covered living space.
In the bioclimatic version, it naturally regulates light and ventilation, so you can enjoy your terrace to the full.

The flat-roofed glazed extension

With its glazed facades and panoramic sliding doors, the contemporary aluminum extension creates a bright, modern volume connected to the outdoors.

Integrating a skylight or full-height joinery maximizes natural light, even in less favorable orientations
