Our first factory
Our plant, located in the heart of the Île-de-France region, represents Wall’up Préfa’s commitment to innovation and sustainability in the construction industry. Founded in 2019 with a pioneering vision for biobased prefabrication. Nestled in Bellevue 77120 Aulnoy, our factory doesn’t just produce eco-friendly building solutions; it’s the symbol of a low-carbon building revolution, localized within the very resources it valorizes.
Hemp Concrete by Wallup
France's first plant for prefabricated hemp concrete insulated panels
Hemp concrete is a mixture of chenevotte (aggregate), lime (binder) and water. The special feature of WALL’UP Préfa panels is that this mixture is prefabricated using a formwork base fixed to an offset timber frame.
In addition to this explanatory diagram describing the composition of our product, see below the CF2B video produced by the Watts-New agency.
