Relative Heat Gain is the combined effect of Shading Coefficient (SC) and U-Value (UV). The lower the relative heat gain value, the more efficient the glass is in restricting heat gain. It describes how much energy penetrates into the building through the windows as a result of solar radiation. This is measured in watts per square meter

RHG = (SC x 637) + (U x 7.8)
RHG can be expressed in both metric and imperial units. To
convert W/m² to Btu/hr ft² divide by 3.154
1 W/m² = 0.317 BTU/ft²
1 W/m².K = 0.176 BTU/hr/ft²/°F

SOLARSTOP coated glass, manufactured by Sanam Glass Company, is warranted to its original customer only, subject to the terms and conditions of Product Limited Warranty which is available upon request from Sanam Glass Company.
