In practice though, most g-values will range between 0.2 and 0.7, with solar control glazing having a g-value of less than 0.5. As a manufacturer of professional glass thickness measuring tools, Linshang Technology can not only help you measure the shading coefficient and SHGC of glass, but...
In response to my critique of the FBC insulated glass requirement in the South Florida, we received a question from an architect, who wrote: “Surely you would not claim that double glazing with a low-e coating on the #2 surface would cause more energy use […] Tags: glass experts, ...

negligible, the R-value and U-factor would be reciprocals. ) If somebody quotes an R-value to a customer, the customer should insist on knowing the NFRC-certified U-factor. (Moreover, some in the business have been known to try to further mislead customers by using center-of-glass R...

An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value...
