Eco-designed products

Eco-design integrates environmental aspects into the design of a product and targets minimizing its impacts throughout the life cycle: extraction, manufacture, transportation, use, and end of life.

An approach that Bel'M illustrates with environmental displays.


The environmental label, initiated by Bel'M in the joinery world and encouraged by the French Ministry of Ecology and Sustainable Development, is the result of this process. Established for the whole product life cycle, it offers a more complete statement than building energy labels, which do not take product use into account.

The aluminium range

The aluminium range has efficient insulation, thanks to its composition and the thermal breaks studied.

Furthermore it has very good air proofing (A4, maximum score). Its score in the use phase is excellent.

However, aluminium is a metal whose extraction and manufacture involve significant environmental impacts, especially in energy consumption terms. This is why the score for the manufacturing phase is fairly low.

But aluminium recycles well, meaning that it gets a good score for the end of the life cycle.

The wood range

The very good performance of wood doors in the manufacturing phase is down to purchasing wood in classes coming from certified sustainable management, and the use of reconstituted cubes of wood that optimizes the quantity of fine wood used.

Furthermore, the new design considerably improves thermal performance, making this range also very efficient in the use phase.

Finally, wood, making up almost the entire door and being a material that recycles well, gives this range a limited impact for the end of life.

The steel range

Even though steel extraction and manufacture involve environmental impacts, the manufacturing phase keeps a correct environmental score, especially due to the use of water-based paints.

This range has very good results for the use phase thanks to its thermal efficiency (Ud 1.0 W/m2.K, among the most efficient on the solid door market) and air proofing (class A4 in the Air, Rain, Wind test).

The C score assigned to the "end of life" step results from the use of the multiple components (steel opening, wood or PVC frame) required to manufacture this range.

At Bel'M, eco-design is not limited to the research and improvement of its product compositions. The brand is also developing its approach within its plants through the use of production processes that contribute to reducing environmental impacts:

  • Waste: optimized recycling and reduced quantities
  • Energy: optimized consumption
  • Water: internal recycling of powder coating effluents and water reuse 
  • Volatile Organic Compounds: change to water-based finishing products
  • Carbon footprint: carried out at our three production sites, this analysis is regularly revised and lets us quantify the effects of the improvements made

Bel'M also contributes to national projects:

  • Feedback on waste organized by the ADEME (French agency for environment and energy management). "50 model companies: further reducing and valuing their waste to reduce costs".
  • The national experiment to make environmental information available initiated by the "Grenelle Environnement". More about this experiment
