Partition walls with sheep wool insulation

Effortless installation – a 1:1 replacement for mineral wool. And it's healthy and sustainable.

Partition walls are more than just room-dividing elements: properly insulated, they improve sound insulation, indoor climate, and comfort.

Fire protection for partition walls

Naturally safe – tested up to EI 90

Sheep’s wool has a self-ignition temperature of 560–600 °C – around twice that of wood (270 °C). In the event of a fire, the fibre melts away from the heat source without dripping or releasing burning particles (d0).

The products recommended for partition walls, ISOLENA Optimal and ISOLENA Klemmfilz, are classified as D-s2, d0 in accordance with EN 13501-1. They contain no chemical flame retardants, relying solely on the natural properties of wool.

Soundproofing from fibre to joint

The varying fibre fineness of sheep’s wool ensures broadband sound absorption and is more effective across the entire frequency spectrum than homogeneous mineral fibres.

The DIN 4109-1:2018-0 (‚Sound insulation in building construction‘) requires a sound insulation value of at least 53 dB. In the Knauf & ISOLENA drylining system, partition walls achieve 54 to 67 dB Rw – which corresponds to the level of confidential meeting rooms.

A detail that makes all the difference: the joints between the floor, ceiling and adjacent structural elements create acoustic weak points. The ISOLENA sheep’s wool felt strip (9 mm, C-s2,d0) seals these joints completely and prevents sound bridges.
