What is the standard thermal performance of channel glass, before the application of thermal-enhancement glass coatings & insulation?

A standard double-glazed, uncoated channel glass wall provides a U-Value of 0.49 and a Solar Heat Gain Coefficient (SHGC) of 0.67.

The thermal performance of channel glass walls can be progressively improved, reaching a U-Value of 0.19, by adding our Low-e coating and a thermal insulation material (TIM), such as Okapane.
