The NEW ETEKT + Low-E Coating Detector allows you to Confirm the invisible Low-E coating is properly installed on your double pane IG units with a single test from a single side. You can also test a triple pane window by testing both sides of the window. During IG fabrication, ensure proper orientation of the Low-E coated glass so it is not damaged by the brushes of the glass washer. Prove to the customer that the invisible, money saving Low-E coating is present on their windows before installation.
