Envelope

Form that meets function.

Compatible technologies

Bring your ideas to life with high performance facade, roofing and envelope systems. Like main or secondary skins, they bend and adapt to the most complex shapes and aesthetic requirements while providing durable, high-impact resistance.

Create decorative and protective facade elements, latticework, perforated facades and urban furniture that bring innovation to life in a wide range of textures, finishes and colors.

Ductal® can be cast into organic shapes, or cut into clean angles. Its mineral nature allows it to add depth and shadow, or simply blend in.

1. Aesthetics

In addition to their superior impact resistance and leak proofing, thin, lightweight Ductal® envelope elements bring enhanced durability. This means more comfort, with the added advantage of the building envelope’s material efficiency translating into increased leasable floor area and lower operational costs in projects of every kind.

Due to the specific fibers used, along with the packing density of the material, Ductal® Envelope differs from other fiber reinforced solutions by retaining its mechanical performances throughout the full service life of the building.

2. Performance

The high durability, resilience, ductility and low porosity of Ductal® not only results in improved energy efficiency (heat and solar control), but an extended life cycle of up to a possible 100-year service life. That’s almost five times longer than with traditional concrete! Aesthetics are also preserved longer, contributing further to reduced operational costs.

Its light weight and versatility means that off-site manufacturing, combined with an optimized supply chain, contribute to lowering the material’s overall carbon footprint.

When it’s time for a change, Ductal® can be recycled using a very low energy process, wherein the material is ground up – much like in a giant pepper grinder.

3. Sustainability

There’s very little that Ductal® can’t do, and our team can guide you every step of the way in creating almost any sort of element you can think of, including:

  • Tailor-made precast façades
  • Large-scale standardized panels
  • “Brise Soleil” and perforated facades
  • Prefabricated unitized façade systems
  • Urban furniture

The Foksal Gallery Foundation art gallery, an iconic example of 1960s architecture, has been given a radical renovation, by reducing the weight of the facade, providing thermal insulation and restoring the mineral appearance of exposed concrete.

The new EDF Campus was inaugurated in 2017 in the Plateau de Saclay business cluster, near the well-known campuses of École Polytechnique and HEC. Built by the architecture firm Emmanuel Combarel Dominique Marrec Architects (ecdm), the building is distinguished by the remarkable volumes of its audacious façades. This technical feat was made possible by the innovative use of Ductal® Envelope...

Pritzker Prize-winner Fumihiko Maki has completed an educational centre, with a series of roof spaces, terraces and courtyards for the Aga Khan Foundation in London. A project achieved with the use of Ductal®. Each year, the foundation organizes the Aga Khan Award for Architecture, one of the world's most prestigious architecture prizes.
