The following table of results is presented in our glass optical & thermal property test report:
We sometimes receive questions about whether the testing fee can be reduced by excluding some optical property results.
Please refer to this page for information on the testing procedures for glass optical and thermal properties. The optical properties serve as intermediate results in determining thermal properties. The solar heat gain coefficient (SHGC) and shading coefficient (SC) are derived from 5 sets of raw data on spectral transmittance/reflectance. All other results are calculated from this same data set without requiring additional testing.
Therefore, even if some optical properties are omitted, the testing procedures remain unchanged, and the testing fee will not be reduced.
