Solar control and shading with ASI® Glass
Minimizing heat gain in summer
|
|
In order to reduce the influx of thermal energy during the summer months, the glazing must be provided with some sort of sun shielding. This may be accomplished by additional coatings on the glass, the roller blinds or venetian blinds. The energy transmission of the entire solar spectrum is determined by the g-value – the smaller the g-value, the more effective the shielding.
