Solar Heat Gain & ShadingGlassmaking & Glazing
Convert Solar Heat Gain Coefficient (SHGC) to Shading Coefficient (SC) and estimate solar radiation heat transmission.
Represents the fraction of solar radiation admitted through a window. Range is 0.0 (fully blocked) to 1.0 (fully admitted).
Calculations based on international structural glass design standards (ASTM E1300 & EN 12600). Glazing safety must be certified by professional engineers for high-rise commercial installations.
Ideal for cold climates where passive winter solar heating is desired. Requires external shading in summer to prevent greenhouse overheating.
