Wide range of applications for soniflex materials

soniflex offers a comprehensive range of products and solutions for sound insulation and acoustic optimization. Our products are used in call centers and offices to create a pleasant working atmosphere and facilitate communication. They help reduce noise and improve room acoustics in restaurants and cafeterias.

Our solutions also have an essential role to play in technical environments such as production halls and workshops by optimizing working conditions and reducing noise levels. In private homes, soniflex products are used to sustainably increase comfort through improved room acoustics and insulation against exterior noises.

Many decades of experience

In 1976, Cellofoam GmbH bought a hot-embossing machine and extended its business activities to include “technical noise control”. Ever since, we have continuously expanded our expertise in this field: from the raw materials to the finished product - the expert knowledge of our qualified employees is the basis of every development and production step.

In 2004 Cellofoam started its international expansion and today has subsidiaries in Turkey and the Czech Republic as well as international joint ventures in Poland, France and Austria. Our constant growth is a sign of our ability to respond proactively to market requirements and create innovative solutions. In 2008, Cellofoam founded its new soniflex business area: a web shop that caters to the noise-control needs of private customers and small commercial operations

We at soniflex are proud to be part of the international Cellofoam family of over 200 employees. At our web shop everything is based on our strong commitment to high-quality goods and the best service for our customers, always with environmental protection in mind. The mission of soniflex is not “only” to meet our customers' needs and expectations, but to exceed them by investing in proactive research and development.
