Stability and safety

General Building Approval for the system
The system bears the DVS quality seal and is certified according to DIN EN 1090-3
Optimum stability for architectural design freedom
Watertightness, air permeability and resistance tested to DIN EN standards
Torsion-resistant supporting structure made of premium quality aluminium with integrated screw channel
Secondary water drainage in the inner sealing level – interior aluminium construction does not get in contact with water
Resistance to external fire exposure from flying sparks and radiant heat with classification B,roof(t1) according to DIN EN 13501-5
Optional use of a laser grid as fall-through protection when the NSHEV is open

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.
