Basic types of glazing with low-emissivity layers and their effects

Abstract

The article deals with the importance of low-emissivity glazing layers to improve energy balance and their significance in maintaining interior visual comfort. It describes the physical nature of radiation and the associated surface emissivity and the effects of changes in surface emissivity of glass, depending on the position of the low-emissivity layer. The paper also discusses principles, advantages and disadvantages of the most common combinations of glass and a low-emissivity layer the so-called “high performance” glass and the so-called “low-e” glass.
