Healthy indoor air

Ventilation, the natural complement to insulation

A high-performance envelope deserves healthy air. Isoltech Green® complements facade insulation with a complete range of ventilation solutions, from the single dwelling to multi-unit buildings.

Why ventilate

The better you insulate, the more air must circulate

A high-performance facade limits heat loss… but also parasitic air exchanges. Without controlled air renewal, humidity, CO₂ and pollutants build up. Ventilation extracts stale air and preserves indoor air quality — and the health of the building fabric.

  • Extracts humidity and limits condensation
  • Reduces mould, odours and pollutants
  • Preserves comfort and the health of the building fabric
  • Optimises the benefits of insulation
