Sun protection against overheating. Sun protection can play an important role in reducing the entry of sunrays through windows. Earlier we told you that the G-value of double glazing is around 0.76, which means that 76% of the sunrays are let through. With the application of sun protection, such as ritzscreens, this value can be reduced to 8-16%.
