When choosing insulation materials, the building industry has to compromise on either price, flammability or ecological impact.
At FenX we found a way to turn industrial waste into handy and high-performance insulation panels that are safe, non-flammable and have a minimal carbon footprint. We provide this solution by offering turnkey production units of insulation panels to our clients, producers of building materials.
Eventually, our clients can meet the market demand with an excellent and ecological insulation, while fulfilling all the market requirements in terms of safety and sustainability at a competitive cost.
