What exactly is Mineral Wool encapsulated in PE-foil?
Mineral wool (MiWo) in PE-foil is a specially finished solution for sound insulation and thermal insulation applications. The mineral wool is completely enclosed in a thin, protective 23-micron polyethylene (PE) foil.
The result: The excellent acoustic properties of mineral wool are preserved while its functionality is further enhanced.
✔ No airborne fibers – safe for use in applications such as chilled ceilings
✔ Protection against moisture – prevents water absorption and sagging
✔ Clean, stable, and long-lasting installation
✔ Versatile applications in ceilings, walls, and technical systems
Our mineral wool encapsulated in PE foil provides a fast, clean, and cost-effective solution for optimizing room acoustics – whether in new buildings or retrofit projects.
The combination of mineral wool and PE foil not only delivers noticeable acoustic improvements but also enhances indoor air hygiene.
