Start saving energy

The new Corona CT 70 windows will reduce heating energy consumption by around 16% in a 1980 single-family home with a floor area of about 140 m2. The thermal image clearly shows the area where heating energy is lost. The red colour represents heat and therefore energy losses.


The thermal image taken after the professional installation of Corona CT 70 windows demonstrates the huge energy gains that can be made from this investment. Previous heat losses have been all but eliminated. You can save 660 litres of heating oil every year for a 1980 single-family home with a floor area of about 180 m2.
