Wussten Sie schon: Dass alle vor 1995 produzierten Fenster technisch völlig veraltet sind?

Windows with old double glazing are technically outdated


THE PERFORMANCE OF MODERN WINDOWS

Compared to old double glazing, new modern windows have a thermal conductivity coefficient over 50% better, even suitable for a passive building. Even more when compared to old single glazing.

Calculation example:     
1982 school building with old double glazing and a building shell area of 2000 m2,
approx. 365 m2 window area.    
* Transmission: The transfer of heat out of or into a building.

 

Energy saved after full renovation of the building

Example calculation: With approx. 365 m2 window area, per year (avge. school building):
