An external screen is indeed a more effective instrument of solar control compared to an internal screen, as solar radiation is, during summer months, intercepted prior to reaching the glass surfaces, avoiding the greenhouse effect and the ensuing overheating of the environments.
On the contrary, Internal screens can allow the light to pass through the glass, requiring finally the removal of the heat accumulated inside the building by means of mechanical ventilation or air-conditioning.
