Biwall is a combined acoustic and thermal insulation panel made up of a 10mm thick high density rubber panel, coupled with a polyester fibre panel of 30mm. Manufactured using recycled raw materials, Biwall has both excellent thermal and sound insulation properties. It has been developed to solve all the most common partition walls applications.

Biwall is part of a family of rubber and polyester fibre products, created with eco-compatible technologies and production processes that allow for more than 92% of recycled and/or regenerated materials to be used.
