LOW-E dETECTION CAPAbILITIEs (CONT.)
IdENTIfyING ThE TyPE Of LOW-E
In addition to identifying the location of low-E coatings, the GC3001 determines the type of low-E on your window. The
meter will specify it as “hard coat’’( aka pyrolytic or on-line coating) or “soft coat” (aka sputtered or off-line coating). If the
Low E is soft coat, the meter will also specify the number of silver-layers as single, double, or triple, based on the coating’s
energy performance. If you happen to know the manufacturer of the glass, in many cases you can identify the exact type
of low-E coating used to make the window. A convenient reference chart is included with the GC3001 meter that lists many
of the common Low E coatings used in the usA. here are some examples.
TRIPLE PANE WINDOWS
The GC3001 will specify if the coating is located on
surface 1, surface 2, surface 3, or surface 3or4. by
moving to the other side of the window, the meter can
specify surface 5 and surface 6. The GC3001 detects
the presence of low-E coatings on the middle pane of
a triple pane unit. It will either show results of surface 3,
or surface 3or4. If there are multiple low E coatings, the
GC3001 will only identify the nearest coating.
