Why healthy indoor air and acoustics in educational and sports buildings is crucial

Large rooms, lots of people, high noise levels: good acoustics are essential for health and learning success in educational buildings.

Children and sports enthusiasts breathe - in relation to their body weight - up to twice as much air as resting adults. This significantly increases the absorption of air pollutants, particulate matter and VOCs, favours respiratory irritation, allergies, fatigue and reduces concentration and performance. Good room acoustics, combined with pollutant-degrading materials like sheep's wool, ensures clear communication, promotes concentration and provides lasting health protection.

Naturally quiet

Acoustic ceilings in schools, nurseries and the like.

Acoustic ceilings are indispensable in classrooms to reduce noise and improve communication. But Not every solution is healthyMany materials can cause fibres to fly or release harmful substances. ISOLENA sheep's wool is a Pollutant-free and pollutant-binding alternative - with tangible added value for learners and teachers.

  • Improved Speech intelligibility and less reverberation
  • Healthy Indoor climate without flying fibres or harmful substances
  • Space-saving good performance even with low insulation thickness
  • Sustainable and fully recyclable

Acoustic ceilings practical example

Economy and ecology in harmony

"In a kindergarten project, we fitted the acoustic ceilings with sheep's wool insulation. During the planning phase, the question arose: 'Can we afford it?'

We did the maths: The total additional cost of the healthy, sustainable solution compared to mineral fibre was only a few hundred euros.

Converted to one year of childcare, that was €0.33 per child per day - far less than a pot of yoghurt!

In return, children and educators breathe clean air for decades, free from flying fibres and pollutants. Saving money here is saving at the wrong end - it's about the health of the next generation."
