Application Healthcare Sector

Acoustic Performance

Weighted sound absorption coefficient (αw)

A single-number rating calculated from measured sound absorption coefficients at standard frequencies.

αw Range 0.00 < αw < 1.00

αw ranges from 0.00 (poor) to 1.00 (perfect).

Calculated in accordance with ISO 11654 using the sound absorption coefficient αp values at standard frequencies.

The measured values are compared with a reference curve to determine the weighted sound absorption coefficient.

Noise Reduction Coefficient

Noise reduction coefficient (NRC)

Calculated in accordance with ASTM C423. NRC is the mathematical average of the measured sound absorption coefficients at 250, 500, 1000 and 2000 Hz.

Rock wool resistance documented above 1000°C for more than 120 minutes.

Humidity Performance

Superior Humidity Resistance of Stone Wool

Stone wool ceiling tiles are documented for humidity resistance and dimensional stability up to 100% RH.

01 Humidity resistance up to 100% RH

Stone wool ceiling tile humidity resistance up to 100% RH.

02 Naturally ventilated areas

Used in naturally ventilated areas.

03 Long-term dimensional stability

Humidity resistance up to 100% RH after 13 years. Stone wool products can withstand extreme climatic conditions and remain dimensionally stable up to 100% RH.

Hygiene Performance

Superior Hygiene Performance of Stone Wool

Stone wool is made from inorganic raw materials, has no nutritional value and therefore provides no sustenance to harmful micro-organisms.

The source comparison shows the stone wool medical-grade tile after 28 days at up to 100% RH compared with a mineral fibre tile after 7 days at up to 95% RH.
