Moisture - gypsum as a natural skin

Gypsum feels at home wherever people feel at home. Gypsum board acts like a skin, capable of absorbing and releasing moisture. At low humidities moisture is released, at high humidities moisture is absorbed. Gypsum products therefore play an active role in regulating and improving the indoor climate.

All Danogips’ products are tested for resistance to moisture. Products tested with resistance up to 70% RH max. are designed for use under normal conditions, i.e. in offices, institutions and similar premises. Products tested with resistance up to 90% RH are designed for use under more extreme conditions and can thus be used in kitchens, laboratories and other rooms with frequent and major changes in the humidity of the air. In the latter case, it is also recommended using special purpose, anticorrosion treated suspension systems.

We recommend however that warehousing & storage conditions should not exceed 70% RH and 50°C.

Testing deflection
Plasterboards, which form the basic material of Danoline products, are tested for flexural strength according to the European Standard EN 520. Subsequently, Danoline products are tested for deflection and load-bearing capacity under certain temperature, humidity and load conditions, all in accordance with the principles set by the European standard EN 13964, 2004, Appendix F.

The tests are carried out under humidity conditions classified as A, B, C or D, depending on the temperature and the relative humidity. The classifications of humidity, deflection and load values can be found in section concerning load-bearing capacity and weight.

We recommend that warehousing & storage conditions should not exceed 70% RH and 50°C.

If Danopor is used as a lining on the back of suspended ceilings, Contur and Linear will fall within category 2/A/12N/m². Other 9,5 and 12,5 mm Danoline suspended ceilings lined with Danopor are categorised as 1/A/12N/m2.
