Whatever your project – new or renovation, tall building or small shop – our ranges allow you to equip the entire building facade in compliance with current standards and regulations.

For many years, Sepalumic has been supplying exceptional architectural projects with joinery that helps to enhance all kinds of facades : offices, shops, car dealerships, schools, cultural spaces and even cafés/hotels/restaurants.

Energy regulations for commercial buildings

The joinery of public-access buildings is subject to strict regulations in terms of insulation and safety and must therefore be chosen with care. It must improve the thermal and sound insulation of the building by meeting defined minimum standards, contribute to occupant safety or even meet aesthetic expectations.

Sepalumic’s aluminium joinery systems are designed in response to these regulations and in particular to RE2020. So, our joinery and facade solutions can be integrated into your construction projects, whether new builds or renovations. Our ranges allow for :

  • optimised insulation to reduce building energy consumption

  • summer-like comfort for occupants

  • compliance with the minimum insulation performance requirements

Minimum lines, maximum performance.

A successful project relies on the intrinsic performance of the joinery, as well as the quality of installation. Thanks to our design offices and our recognised know-how, we develop joinery systems adapted to the various manufacturing constraints of our customers and to the requirements of building specifiers. At the cutting edge of performance, our ranges guarantee simplified installation and a neat appearance for perfect integration into all your architectural projects.


Thus, in line with current architectural trends, our aluminium profiles have minimal, contemporary lines while maintaining increased thermal and insulation performance. Our ranges of aluminium windows, doors and facades for the commercial sector offer comfort and peace of mind to building occupants.

  • Maximum insulation and watertightness thanks to innovative technical processes

  • More light can enter thanks to the slim aluminium profiles

  • Meticulous design and customisation as desired (colours, shape, size and accessories)

  • Compliance with safety standards for products and people
