COMFORT AND TECHNOLOGY
The intelligent use of highly efficient materials limits the minimum surface temperature on the inside of glass constructions, thus preventing condensate and mould formation.
Mould grows on surfaces at a relative humidity of just 80 percent or higher. When the indoor temperature is 20°C and relative humidity is 50 percent (standard conditions), this corresponds to a surface temperature of 12.6 °C.
Such data is used to calculate the fRsi-value, a coefficient that indicates the likelihood of mould growth. If this value is less than 0.7, there is a risk of mould formation.
For the Glass Roof PR60 Passivhaus this value is a stable 0.79. This corresponds to a minimum surface temperature of 14.8 °C, which is an ideal temperature to ensure comfort and energy savings.
