How we make it

We take cardboard, a natural paper and pulp product and drench it in Cellx. Our solution treats the cardboard so that it hardens in what we call fossilized. After lamination our production process delivers ready to use cardboard panels of incredible lightness and strength.
The two-step process takes place in our production centre in Middelstum in the North of the Netherlands.
After the cardboard is processed there’s a number of customized finishes available to your specification in terms of laminating and surface printing.
We provide standard cardboard sizes and thicknesses as well as offer customized solutions on thickness and construction.

How does Cellx compare?

The construction industry is changing rapidly.
The need for stronger safety regulations together with more sustainable requirements put Cellx at the forefront of tomorrows construction needs in comparison to alternative materials that are more established.
In facts gathered from different sources, together with our own independent testing, Cellx scores highest on the three most important factors: weight, fireproof and environmentally friendliness.
