Ecological products
For us, sustainability is not a separate product but a choice that returns in every project. Recycled PET for acoustics, reboard instead of plastic, eco-friendly banners, recycled wood-look cladding, and systems where you replace only the fabric rather than the whole frame. Herva-Doublet is ISO 14001 certified.

What this gives you
From first sketch to maintenance — one partner who handles everything in-house.
One partner, from A to Z
You call one number. We measure, design, produce, install and maintain. No fragmented responsibility, no waiting on subcontractors pointing at each other.
You see it before it exists
A 3D visualisation of your own façade or space, by day and by night. We only start producing once that image is right. No surprises afterwards.
In-house production in Olen
Custom work from our own workshops, without intermediaries. That means a shorter lead time, a sharper price, and changes that are genuinely still possible.
Built to last
ISO 9001 and ISO 14001. Colourfast, weather-resistant materials and energy-efficient LED lighting. With long-term service and maintenance.
