Ensuring Energy Efficiency: Specifying Windows and Curtain Walls for Cold Climates.

The article focuses on the move of manufacturers to design curtain wall and operable vents with triple glazing to increase stringency of model energy codes and zero-carbon sustainability goals. It says that systems designed for triple glazing help achieve the needed low-U-factors for the buildings. It mentions that low U-factors can be achieved with suspended coated film (SCF) technology insulating glass (IG) units without added weight. Moreover, the occurrence of heat transfer is discussed.
