Plyterra Phon is the brand for sound-insulation plywood. Alongside with high-quality birch plywood, the structure of the panel also includes sound absorbing barrier in its central part. There are three types of core available for Plyterra Phon. They are cork, rubber and rubber-cork composite. The core can be chosen by the customer according to his needs: cork makes the boards lighter in comparison with standard plywood, while plywood with a special layer of technical rubber in the middle provides better damping of vibration and protection against noise.

Upon the agreement with a client, the plywood can be overlaid with HPL. The coating protects plywood from mechanical damages, UV-light, humidity, changing weather conditions. There are over 100 various designs of HPL.
