The acoustic design you have in mind does not exist yet. We design and make it, from wall to finished product.
We design and produce acoustic walls, panels and products from 100% recycled PET-felt, in our own CNC workshop in Hellevoetsluis, the Netherlands.
Have an idea for a felt product? We think along, make it manufacturable and produce it, from first prototype to series. Under your own brand or as white label. Product development with PET-felt is a craft of its own, and it is where we feel at home.
Start a development project →We translate your idea into a design that works in felt: acoustically, aesthetically and in production.
Fast iterations on our own CNC. Touch, adjust and refine until it is right.
From small batch to series: consistent, circular and made in the Netherlands.

We always thought PET bottles on the wall were a good idea. The KVK jury now agrees: Viltr is among the 100 most innovative companies in the Netherlands.
