Material

For a Healthy Environment

Smart acoustic polyester

We take responsibility

bluefiber products are made entirely from a single polymer, making them a sustainable acoustic solution. Produced largely from recycled PET bottles, these high-tech materials are also fully recyclable. They are odourless and, unlike many other fibrous materials, pose no health risks to users or installers. The same polyester used in everyday clothing forms the basis of every bluefiber product.

Durable and lightweight for lasting sound insulation

Smart acoustic polyester offers significant advantages over alternative materials. It is highly resistant to ageing and environmental influences, ensuring long-term durability. Thanks to its open-pore structure, *bluefiber* efficiently absorbs and dampens sound while remaining free from harmful substances and chemical additives. The nonwoven material is fully recyclable, even after years of use, and can be reprocessed for renewed production, reducing the need for new resources. Compared with wood or other fibrous materials, polyester is much lighter, its fibres are more resistant to breakage, and the products are easier to handle. All *bluefiber* products are flame-resistant and tested in accordance with EN 13501.

Only the best properties combined

Smart acoustic polyester from *bluefiber* is both sustainable and long-lasting, combining the material’s finest properties to deliver reliable and consistent performance.
