About sonowall
Under the sonowall brand, TWOPS GmbH manufactures acoustic pictures, acoustic modules, wall absorbers, ceiling sails, baffles, freestanding absorbers, acoustic partitions, acoustic curtains, desk absorbers, acoustic poufs and acoustic columns to improve room acoustics. Production takes place in Leverkusen by hand; the shape, size and color of the elements are freely selectable, and acoustic pictures are manufactured to the millimeter. The absorbers are predominantly thermally pressed from recycled PET fibers, entirely without binding, blowing or solvent agents, and are themselves 100 % recyclable. Printed acoustic fabrics are produced by digital printing with water-based inks; frames are available in aluminum, lacquered, powder-coated in RAL colors, or in four hardwood varieties. The products are B1-certified and therefore also suitable for schools and kindergartens. Areas of application include offices, hotels, gastronomy, schools, daycare centers and living spaces.
