PPG INTERCEPT WARM EDGE SPACER- ANY GOOD?

I AM RESEARCHING WINDOWS AND A LOCAL CO HAS DUAL PANE LOWE ARGON FILLED WINDOWS WITH THE PPG INTERCEPT WARM EDGE SPACER AND 7/8" THICK INSULATING GLASS. iS THIS SPACER ANY GOOD AS WELL AS THE GLASS THICKNESS. THANKS FOR ALL COMMENTS

Though Superspacer and especially TPS perform better, Intercept is still a good product and will do you a nice job on mid-grade products. On premium windows, I would make sure the spacer is SS or TPS. (Just my opinion)
And 7/8" is just fine for glass unit thickness.
