Energy saving
The solar factor g indicates the proportion of solar energy transmitted through the glass. The higher the coefficient "g", the more energy you gain between seasons, but the more it heats up in summer!
A high-performance glass will have a "g" coefficient of 58 to 62%, which means that 58% of the solar energy passes through the glass, or that the glass retains 42% of the energy.
A sun protection glass will have a coefficient "g" of 30 to 20 % or even 15%, so it stops more than 70% of the solar radiation.
