Tranquil ECOCORE is entirely made of PET fibre that has been thermally bonded rather than usual chemical binders. PET is inherently resistant to fire, moisture, vermin, bug, mildew, and germs, thus no chemical additions are required. Tranquil ECOCORE Panels are also suitable for use as a high-quality finish pin board. These boards offer a visually appealing acoustic solution for commercial settings and interior design applications.
