Glass Inspection

If you are shopping for a glass thickness meter, you will find that EDTM offers two handheld models: the GC3200 Glass-Chek ELITE and the GC3001 Glass-Chek PRO. Both measure glass and air space thickness, identify Low-E coatings, and test a window from one side. So which one do you actually need?This guide...

A MIG thickness gauge measures glass and air space thickness in sealed insulating glass units. MIG stands for Manual IG Thickness Gauge. Laser reflections off the glass surfaces appear on the gauge's graduated scale, and the distances between those reflections give you the thickness of each pane and the a...

A glass thickness gauge is a handheld meter that measures the thickness of each glass pane, the air space between them, and the overall thickness of an insulated glass unit. It reads from one side of the window, so you can test installed windows and order the correct replacement IG unit without guesswork....

Low E, VLT, and glass performance describe different characteristics of a window. Low E refers to a low emissivity coating designed to influence radiant heat transfer through glazing. VLT, or Visible Light Transmission, describes how much visible...

Why Identifying Low E Glass Matters One of the easiest ways to make the wrong recommendation is to assume you know what type of glass is installed. Two windows may look identical. Both may appear clear. Both may have similar reflectivity. Yet one could have a Low E coating while the other does not. ...

Let’s cut to the chase: If you’re in the window or glass game and you're not using EDTM’s tools, you’re leaving money and reputation on the table. Accuracy is everything. One wrong measurement and BAM, you’re redoing an entire install, eating up time, money, and your client’s trust. That’s where EDTM’s Low-E ...

When it comes to producing, installing, or inspecting architectural glass, precision is non-negotiable. Inaccurate assumptions about glass thickness, airspace, or Low-E coatings can lead to performance failures, warranty issues, and failed inspections. That’s why leading professionals rely on EDTM’s suite ...
