Triple or Quadruple Glazing?

Comparison of basic thermal insulation properties of triple glazing and quadruple glazing. It also compares the heat transfer coefficient of glazing, transmittance of solar radiation, the weight of glass and other basic properties of glazing. It deals with the effect of number and position of low-emission coating the quadruple glazing on the heat transfer coefficient. Reducing weight of quadruple glazing using thin heat-strengthened glass and dimensional constraints.
