Currently, the industry offers low-E on both the #2 surface and the #3 surface. On which surface would you recommend applying the coating to achieve the best solar performance?
Most commercial or residential buildings in Russia and CIS region are glazed with the low-E coating on the #5 or/and #2 surface in triple glazed insulating units, in double glazed units – on the #3. For the maximum benefit in reducing heat gain, it is recommended to use two Low-E coatings in triple glazed unit on the #2 and #5 surfaces. Solar control coatings on the #2 surface (double – and triple glazed units) reduces solar heat gain to the building’s interior.
