Colour coating according to RAL colours

The intelligent use of highly efficient materials limits the minimum surface temperature on the inside of the glass roof construction, 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 humidity is 50 per cent (standard conditions), this corresponds to a surface temperature of 12.6 °C.

This data is used to calculate the f_Rsi value. A coefficient which indicates the likelihood of mould growth. If this value is less than 0.7, there is a risk of mould forming.

The value is stable on the level 0.73 for the Glass Skylight FE Passivhaus. This corresponds to a minimum surface temperature of 13.3 °C, which is an ideal temperature to ensure comfort and save energy.
