Solar gain
In the wintertime, the heat from the sun entering through the windows is a usable solar gain.g = 0.64
Solar protection
In warm climates and in rooms with large window areas, a sun protective coating provides a better indoor climate during summer periods.★★☆
Sound insulation
A combination of laminated glass and optimal glass thickness provides better sound insulation against noise from outside (traffic, playgrounds, etc). RwdB = 29(-1;-3)
