What E-CLEAR A can offer

Easy to process glass

Thanks to advanced coating technology, new SGG E-CLEAR A provides glass processors with an easier to process, more durable low-E solution that does not require edge-deletion when used with approved sealants. Moreover and to simplify daily business of glass processor, new SGG E-CLEAR A is a single stock product for both annealed and tempered applications with an extended storage shelf life and improved toughening cycle time.

Winter Comfort

Thanks to a low centre-pane U-value of 1.3 W/m2K, SGG E-CLEAR A reduces heat loss through windows, making homes more comfortable and reducing cold spots around areas of glazing.
