Solar Optical Performance
THERMAL COMFORT GUIDE
Ts Solar Transmittance (%)
Rs Solar Reflectance (%)
As Solar Absorbance (%)
Solar radiation is always partially transmitted through, absorbed or reflected by the fabric. The sum of all 3 equals 100. Ts + Rs + As = 100 % of solar energy.
Glazing and Fabric
Test data has been supplied using the following glazing types:
A – Clear single glazing (4mm float)
B – Clear double glazing (4mm float + 12mm space + 4mm float)
C – Double glazing low-e coating and argon filled (4mm float + 16mm space + 4mm float)
D – Reflective double glazing with low-e coating and argon filled (4mm + 16mm space + 4mm float)
GTOT (Range 0-1)
The Solar Heat Gain Coefficient (SHGC), measures the window’s (fabric and glass) ability to transmit solar energy into a room. The SHGC is commonly referred to as g-tot. SHGC/ g-tot is a calculation of the g-values of the solar protection device (fabric) and the glazing (A, B, C, D). The lower the GTOT value, the greater its ability to insulate against solar heat build-up.
