XPEL bulletin puts Low-E checks at the center of film selection

XPEL has added a glass-meter technical bulletin to its public resource library, emphasizing a practical risk for architectural-film installers: identifying one Low-E coating does not necessarily identify every coating in the window. The company lists the bulletin under October 6, 2026.

The six-page FAQ concerns the EDTM Glass-Chek ELITE GC3200. XPEL says an exterior reading can detect the first Low-E coating encountered while missing another farther into the insulated glass unit. It calls for an interior check when evaluating those coatings and measurements from both sides of triple-pane windows.

The document also treats an exposed room-side Low-E coating as a warning requiring further evaluation before preparation or film selection. Its broader point is that the glass assembly, coating position and reading method belong in the installation decision. A meter reading alone is not approval for a particular film.

This is guidance for an existing instrument, rather than the announcement of a new meter. EDTM’s product information describes the GC3200 as a tool for measuring glass, air spaces and laminate layers and identifying Low-E coatings. The manufacturer also publishes operating instructions for interpreting its results.

For residential and commercial projects, the useful takeaway is documentation: establish the glazing construction before promising a film solution or energy benefit. Installers should use the current instrument instructions together with the film supplier’s compatibility and warranty requirements. TintNews has not independently tested this meter or the bulletin’s procedures.
