• To be installed and used in rooms with a relative humidity not exceeding 70% for prolonged periods.
• Designed for the reinforced T-15 grid system and the planks are demountable.

• Sound absorptionGyptone planks provide sound absorption when used inconjunction with an air space behind the ceiling. Tests havebeen carried out to BS EN 20354: 1993 and ISO 354: 1985.The single figure rating practical sound absorption coefficientsαw, and sound absorption classes, are calculated in accordancewith BS EN ISO 11654: 1997. The Noise Reduction Coefficient(NRC) is calculated in accordance with ASTM C423-90a: 1992.ACTIVair technologyThough we don’t notice them, impurities such as VOCs areoften present in the air we breathe – emitted from furniture,carpets and building materials. Long-term exposure to thesecan potentially cause health problems and reduce generalwell-being. Clean air, on the other hand, can speed uppatient recovery in hospitals, reduce absence at work, andincrease pupils’ concentration at school. ACTIVair is our latesttechnology designed specifically to convert formaldehyde, acommon VOC, into non-harmful inert compounds, removingup to 70% of the formaldehyde concentration in the indoor air.This clever technology continues to work over 50 years, andwhilst alternative solutions absorb formaldehyde, they don’tdecompose like ACTIVair risking re-emission at a later date.
