Absorbent-insulating panels

Absorbent and insulating noise-absorbing screens composed of a concrete panel covered on one or two sides with highly absorbent slabs from a mixture of concrete and wood fibers.

For specific projects, we also make patterns or reliefs according to the expectations of our customers.
