Saint-Gobain has recently launched SGG E-Clear A, an entry-level low-emissivity glass designed to achieve a minimum WER "B" rating but with a number of specific advantages over existing online products. According to Saint-Gobain, higher clarity and lack of haze are principle benefits over many pyrolytic (hard-coated) glasses, along with lower surface reflection and better insulation. Saint-Gobain's marketing manager, Karen Clough, explained the market positioning for the new product: "Saint-Gobain has always led the field with high performance glasses of all varieties and functions for the architectural and larger domestic installation markets. Now, we have E-Clear A, designed specifically for the smaller domestic retrofit businesses seeking to achieve a good WER that outperforms existing products int he sector in a number of ways." SGG E-Clear A has an optimum centre pane "U" Value of 1.3 W/m2K, enabling it to achieve a minimum WER "B" rating with warm edge spacer and Planiclear counter pane. For processors, it has an improved toughening cycle time, an elongated shelf life, and does not require edge-deletion.
