Product description

Gyptone quattro 41 comprises a 12.5mm gypsum core, with a geometric array of 12mm square perforations. The reverse of the board incorporates an acoustic fleece which provides sound absorption performance. As with all products in the Gyptone range, Gyptone quattro 41 is supplied with ACTIVair technology as standard, which absorbs and converts formaldehyde into non-harmful inert compounds.

 

Board performance

Sound absorption

Gyptone boards provide sound absorption when used in conjunction with an air space behind the ceiling or wall. Tests have been carried out to BS EN 20354: 1993 and ISO 354: 1985. Increased levels of sound absorption can be achieved by including Isover insulation over the back of the ceiling. The single figure rating practical sound absorption coefficients αw, and sound absorption classes, are calculated in accordance with BS EN ISO 11654: 1997. The Noise Reduction Coefficient (NRC) is calculated in accordance with ASTM C423-90a: 1992.

 

ACTIVair technology

Though we don’t notice them, impurities such as VOCs are often present in the air we breathe - emitted from furniture, carpets and building materials. Long-term exposure to these can potentially cause health problems and reduce general well-being. Clean air, on the other hand, can speed up patient recovery in hospitals, reduce absence at work, and increase pupils’ concentration at school. ACTIVair is our latest technology designed specifically to convert formaldehyde, a common VOC, into non-harmful inert compounds, removing up to 70% of the formaldehyde concentration in the indoor air.

This clever technology continues to work over 50 years, and whilst alternative solutions absorb formaldehyde, they don’t decompose like ACTIVair risking re-emission at a later date. Formaldehyde reduction is based on experimental data following ISO16000-23 standards from 0.4m2 to 1.4m2 installed/ m3 room. Lifetime is based on a calculation assuming constant formaldehyde reduction with indoor formaldehyde concentration of 25µg/m3 for ceiling, drywall or combined drywall and ceiling configurations.

 

CasoLine CURVE

Gyptone boards can be used in conjunction with the CasoLine curve system to form a curved finish with a minimum radius of 6000mm.
